Computed tomography-guided localization with laser angle guide for thoracic procedures. Lin Frank Cheau-Feng,Tsai Stella Chin-Shaw,Tu Hsien-Tang,Lai Yi-Lin,Wu Tzu-Chin Journal of thoracic disease Computed tomography (CT)-guided lung procedures such as preoperative localizations, biopsies, and ablations are associated with morbidity even mortality. Often, the puncture angle is determined by the 'experienced hand' without a precise guide. We describe here the Laser Angle Guide Assembly to direct and steer the puncture angles precisely. It decreases procedure-related complications, saves time, reduces costs, avoids repeated punctures, and minimizes radiation exposures. 10.21037/jtd.2018.05.162
Feasibility and safety of fine positioning needle-mediated breathing control in CT-guided percutaneous puncture of small lung/liver nodules adjacent to diaphragm. Wu Qingde,Cao Bihui,Zheng Yujin,Liang Baoxia,Liu Manting,Wang Lu,Zhang Jinling,Meng Liyan,Luo Shaoyong,He Xuxia,Zhang Zhenfeng Scientific reports To assess the efficacy, safety, and feasibility of a separate inserted positioning fine needle-mediated breathing-control technique applied to computed tomography (CT)-guided percutaneous puncture for biopsy or microwave ablation (MWA) of small lung/liver nodules near diaphragm. Total 46 patients with pulmonary/liver small nodules (≤ 3 cm in size) near diaphragm(nodule within 1 cm distance to the diaphragm)were undergone percutaneous biopsy ( n = 15) or MWA (n = 31) under the guidance of CT, and a separate positioning fine needle-mediated breathing-control technique was applied for the precise punctures. CT plain scan was performed to monitor the complications after the procedure. The patient baseline data, operation details, successful rate, major complications as well as radiation dose during the procedure were recorded and analyzed. With the assistance of a fine positioning needle insertion for controlling the breathing, the puncture success rate for biopsy or MWA reached 91.30% (42/46). For biopsy, the mean nodule diameter, nodule distance to the diaphragm, puncture time and radiation dose during CT scan were 2.27 cm ± 0.74, 0.61 cm ± 0.24, 18.67 min ± 6.23, 28.84 mSv ± 6.99, respectively; For MWA, the mean nodule diameter, nodule distance to the diaphragm, puncture time and CT radiation dose were 2.35 cm ± 0.64, 0.69 cm ± 0.23, 38.71 min ± 13.65, 33.02 mSv ± 8.77, respectively. Totally, there were three and four cases found minimal puncture-related hemoptysis and pneumothorax needed no additional treatments, respectively. We recently developed and verified a feasible, safe and highly effective puncture technique with reasonable radiation dose for CT-guided biopsy or MWA for small nodules abutting diaphragm, therefore worthy of extensive application to similar clinical situations. 10.1038/s41598-021-83036-z
A Novel Laser Angle Selection System for Computed Tomography-Guided Percutaneous Transthoracic Needle Biopsies. Canadian Association of Radiologists journal = Journal l'Association canadienne des radiologistes To evaluate a novel laser angle selection system (LASS) for improving the efficiency of a computed tomography (CT)-guided percutaneous transthoracic needle biopsy (PTNB). Thirty-eight patients referred for CT-guided PTNB were randomly separated into a LASS-assisted puncture group (18 patients) or conventional freehand control group (20 patients). The puncture time, number of control CT scans, and patients' radiation dose were compared for each group. The lesion size, target-to-pleural distance, planned puncture depth, and angle of the two groups were not significantly different. LASS-assisted PTNB significantly reduced the number of control scans (1.7 ± 0.8 vs 3.5 ± 1.5, < .001) and the mean operation time (12.0 ± 4.3 min vs 28.8 ± 13.3 min, < .001) compared with the conventional method. The corresponding room time (27.1 ± 6.6 min vs 44.1 ± 14.4 min, < .001) and total radiation dose (7.9 ± 1.0 mSv vs 10.1 ± 1.7 mSv, < .001) of each procedure also decreased significantly. Fifty-six percent (10/18) of the operations hit the target on the first needle pass when using LASS compared with 10% (2/20) using the conventional method. Compared with a conventional method, this novel laser angle simulator improves puncture efficiency with fewer needle readjustments and reduces patient radiation dose. 10.1177/08465371221133482
"Direct MPR": A Useful Tool for Oblique CT Fluoroscopy-Assisted Puncture. Sato Rui,Aramaki Takeshi,Yoza Kiichiro,Iwai Kenji,Moriguchi Michihisa,Asakura Koiku,Endo Masahiro,Ito Takahiro Cardiovascular and interventional radiology OBJECTIVE:Conventional multiplanar reconstruction (MPR) imaging can be used as a tool for planning oblique puncture procedures, but it takes a few minutes to reconstruct and is not appropriate for real-time CT fluoroscopy-assisted puncture. Recently, new MPR technology has been used that requires only 8 s and makes it possible to obtain a nearly real-time CT fluoroscopy-assisted oblique puncture. We refer to it as "direct MPR." This is the first clinical report of this technique. METHODS:Since February 2016, we have performed real-time, CT-guided oblique punctures with this new technology, "direct MPR," using an angio-CT system. We retrospectively reviewed all of our procedures with this new method between February 2016 and June 2016. RESULTS:We used this technique for 14 cases during the study period. Eight cases were radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC), four were biopsies (lung and adrenal gland), and two were for percutaneous abscess drainage. Six of eight RFA cases were for HCC located immediately below the diaphragm. Both of the drainage cases were abscesses located immediately below the diaphragm. All procedures were successfully completed. The average length of the lesion in the RFA cases was 15.4 ± 3.2 mm. The average length of the lesions in all of the cases was 30.9 ± 31.9 mm. The average craniocaudal angle was 32.5° ± 14.0°. CONCLUSIONS:Direct MPR makes CT-guided oblique puncture for inaccessible targets, especially those located immediately below diaphragm, easier and safer.

Pneumothorax rates in CT-Guided lung biopsies: a comprehensive systematic review and meta-analysis of risk factors. The British journal of radiology OBJECTIVE:This systematic review and meta-analysis investigated risk factors for pneumothorax following CT-guided percutaneous transthoracic lung biopsy. METHODS:A systematic search of nine literature databases between inception to September 2019 for eligible studies was performed. RESULTS:36 articles were included with 23,104 patients. The overall pooled incidence for pneumothorax was 25.9% and chest drain insertion was 6.9%. Pneumothorax risk was significantly reduced in the lateral decubitus position where the biopsied lung was dependent compared to a prone or supine position [odds ratio (OR):3.15]. In contrast, pneumothorax rates were significantly increased in the lateral decubitus position where the biopsied lung was non-dependent compared to supine (OR:2.28) or prone position (OR:3.20). Other risk factors for pneumothorax included puncture site up compared to down through a purpose-built biopsy window in the CT table (OR:4.79), larger calibre guide/needles (≤18G vs >18G: OR 1.55), fissure crossed (OR:3.75), bulla crossed (OR:6.13), multiple pleural punctures (>1 vs 1: OR:2.43), multiple non-coaxial tissue sample (>1 vs 1: OR 1.99), emphysematous lungs (OR:3.33), smaller lesions (<4 cm 4 cm: OR:2.09), lesions without pleural contact (OR:1.73) and deeper lesions (≥3 cm vs <3cm: OR:2.38). CONCLUSION:This meta-analysis quantifies factors that alter pneumothorax rates, particularly with patient positioning, when planning and performing a CT-guided lung biopsy to reduce pneumothorax rates. ADVANCES IN KNOWLEDGE:Positioning patients in lateral decubitus with the biopsied lung dependent, puncture site down with a biopsy window in the CT table, using smaller calibre needles and using coaxial technique if multiple samples are needed are associated with a reduced incidence of pneumothorax. 10.1259/bjr.20190866
Pneumothorax and pulmonary hemorrhage after C-arm cone-beam computed tomography-guided percutaneous transthoracic lung biopsy: incidence, clinical significance, and correlation. BMC pulmonary medicine OBJECTIVE:This study aimed to assess the incidence and clinical significance of pneumothorax (PTX) and pulmonary hemorrhage (PH) after percutaneous transthoracic lung biopsy (PTLB) guided by C-arm cone-beam computed tomography (CBCT). Furthermore, this study aimed to examine the relationships between PTX and PH with demographics, clinical characteristics, imaging, and PTLB parameters. METHODS:A retrospective analysis was conducted on 192 patients who underwent PTLB at our hospital between January 2019 and October 2022. Incidences of PTX and PH were recorded. PTX was considered clinically significant if treated with chest tube insertion (CTI), and PH if treated with bronchoscopes or endovascular treatments. The various factors on PTX and PH were analyzed using the Chi-squared test and Student t-test. Logistic regression analyses were then used to determine these factors on the correlation to develop PTX and PH. RESULTS:PTX occurred in 67/192 cases (34.9%); CTI was required in 5/67 (7.5%). PH occurred in 63/192 cases (32.8%) and none of these cases required bronchoscopes or endovascular treatments. Lesion diameter (OR = 0.822; OR = 0.785), presence of pulmonary emphysema (OR = 2.148), the number of samples (OR = 1.834), the use of gelfoam (OR = 0.474; OR = 0.341) and ablation (OR = 2.351; OR = 3.443) showed statistically significant correlation to PTX and PH. CONCLUSIONS:CBCT-guided PTLB is a safe and effective method for performing lung biopsies. The use of gelfoam has been shown to reduce the occurrence of PTX and PH. However, caution should be exercised when combining radiofrequency ablation with PTLB, as it may increase the risk of PTX and PH. 10.1186/s12890-023-02822-9
Utilization of the track embolization technique to improve the safety of percutaneous lung biopsy and/or fiducial marker placement. Baadh Amanjit S,Hoffmann Jason C,Fadl Ahmed,Danda Dipan,Bhat Vijay R,Georgiou Nicholas,Hon Man Clinical imaging PURPOSE:The purpose of the study was to describe and present outcomes of the track embolization technique with absorbable hemostat gelatin powder during percutaneous computed tomography (CT)-guided lung biopsy and/or fiducial marker placement versus the standard of care (no track embolization) in an attempt to decrease rates of pneumothorax (PTX), chest tube placement, hemorrhage and/or complications, and average cost per patient. MATERIALS AND METHODS:An institutional review board-approved, case-control, retrospective study was performed in which 125 consecutive patients who underwent track embolization were compared with 124 consecutive controls at one institution. For subjects in whom the track embolization technique was utilized, it was performed passively through a coaxial needle as it was removed. All procedures were performed by one of three attending interventional radiologists. For each group, medical records and procedure images were reviewed for PTX occurring postprocedure, PTX requiring chest tube placement, and occurrence of minor or major complication and/or hemorrhage. Comparison was made with published complication rates, and a cost-per-patient analysis was performed. Statistical analysis was performed utilizing Fisher's Exact Test. RESULTS:In track embolization cases versus controls, there were statistically significant reduction in PTX (8.8% vs. 21%; P=.007) and reduction in PTX requiring chest tube placement (4% vs. 8.1%; P=.195). This compares favorably to previously published rates of PTX and chest tube placement of 8%-64% and 1.6%-17%, respectively. None of the pneumothoraces occurring at time of needle placement increased in size with use of the track embolization technique. There were no major complications (including neurological sequela) in the track embolization group. In track embolization cases versus controls, there was a statistically significant reduction in both the rate of major hemorrhage (0% vs. 4%; P=.029) and average cost per patient ($262.40 vs. $352.07; P=.044). CONCLUSIONS:CT-guided percutaneous lung biopsy and/or fiducial marker placement were safer utilizing the track embolization technique during trocar removal. In addition, this technique was cost effective in the study population. 10.1016/j.clinimag.2016.06.007
Comparison of a Patient-Mounted Needle-Driving Robotic System versus Single-Rotation CT Fluoroscopy to Perform CT-Guided Percutaneous Lung Biopsies. Journal of vascular and interventional radiology : JVIR PURPOSE:To compare the effectiveness of percutaneous lung biopsy using a patient-mounted needle-driving robotic system with that using a manual insertion of needles under computed tomography (CT) fluoroscopy guidance. MATERIALS AND METHODS:In this institutional review board approved study, the cohort consisted of a series of patients who underwent lung biopsies following the intention-to-treat protocol from September 2022 to September 2023 using robot (n = 15) or manual insertion under single-rotation CT fluoroscopy (n = 66). Patient and procedure characteristics were recorded as well as outcomes. RESULTS:Although age, body mass index, and skin-to-target distance were not statistically different, target size varied (median, 8 mm [interquartile range, 6.5-9.5 mm] for robot vs 12 mm [8-18 mm] for single-rotation CT fluoroscopy; P = .001). No statistical differences were observed in technical success (86.7% [13/15] vs 89.4% [59/66], P = .673), Grade 3 adverse event (AE) (6.7% [1/15] vs 12.1% [8/66], P = .298), procedural time (28 minutes [22-32 minutes] vs 19 minutes [14.3-30.5 minutes], P = .086), and patient radiation dose (3.9 mSv [3.2-5.6 mSv] vs 4.6 mSv [3.3-7.5 mSv], P = .398). In robot-assisted cases, the median angle out of gantry plane was 10° (6.5°-16°), although it was null (0°-5°) for single-rotation CT fluoroscopy (P = .001). CONCLUSIONS:Robot-assisted and single-rotation CT fluoroscopy-guided percutaneous lung biopsies were similar in terms of technical success, diagnostic yield, procedural time, AEs, and radiation dose, although robot allowed for out-of-gantry plane navigation along the needle axis. 10.1016/j.jvir.2024.02.023
Manual aspiration of a pneumothorax after CT-guided lung biopsy: outcomes and risk factors. The British journal of radiology OBJECTIVE:Quantify the outcomes following pneumothorax aspiration and influence upon chest drain insertion. METHODS:This was a retrospective cohort study of patients who underwent aspiration for the treatment of a pneumothorax following a CT percutaneous transthoracic lung biopsy (CT-PTLB) from January 1, 2010 to October 1, 2020 at a tertiary center. Patient, lesion and procedural factors associated with chest drain insertion were assessed with univariate and multivariate analyses. RESULTS:A total of 102 patients underwent aspiration for a pneumothorax following CT-PTLB. Overall, 81 patients (79.4%) had a successful pneumothorax aspiration and were discharged home on the same day. In 21 patients (20.6%), the pneumothorax continued to increase post-aspiration and required chest drain insertion with hospital admission. Significant risk factors requiring chest drain insertion included upper/middle lobe biopsy location [odds ratio (OR) 6.46; 95% CI 1.77-23.65, = 0.003], supine biopsy position (OR 7.06; 95% CI 2.24-22.21, < 0.001), emphysema (OR 3.13; 95% CI 1.10-8.87, = 0.028), greater needle depth ≥2 cm (OR 4.00; 95% CI 1.44-11.07, = 0.005) and a larger pneumothorax (axial depth ≥3 cm) (OR 16.00; 95% CI 4.76-53.83, < 0.001). On multivariate analysis, larger pneumothorax size and supine position during biopsy remained significant for chest drain insertion. Aspiration of a larger pneumothorax (radial depths ≥3 cm and ≥4 cm) had a 50% rate of success. Aspiration of a smaller pneumothorax (radial depth 2-3 cm and <2 cm) had an 82.6% and 100% rate of success, respectively. CONCLUSION:Aspiration of pneumothorax after CT-PTLB can help reduce chest drain insertion in approximately 50% of patients with larger pneumothoraces and even more so with smaller pneumothoraces (>80%). ADVANCES IN KNOWLEDGE:Aspiration of pneumothoraces up to 3 cm was often associated with avoiding chest drain insertion and allowing for earlier discharge. 10.1259/bjr.20220366
Pneumothorax Incidence with Normal Saline Instillation for Sealing the Needle Track After Computed Tomography-Guided Percutaneous Lung Biopsy. Cardiovascular and interventional radiology PURPOSE:To determine whether instillation of normal saline solution for sealing the needle track reduces incidence of pneumothorax and chest tube placement after computed tomography-guided percutaneous lung biopsy. MATERIALS AND METHODS:A total of 242 computed tomography-guided percutaneous lung biopsies performed at a single institution were retrospectively reviewed, including 93 biopsies in which the needle track was sealed by instillation of 3-5 ml of normal saline solution during needle withdrawal (water seal group) and 149 biopsies without sealing (control group). Patient and lesion characteristics, procedure-specific variables, pneumothorax and chest tube placement rates were recorded. RESULTS:Baseline characteristics were comparable in both groups. There was a statistically significant decrease in the pneumothorax rate (19.4% [18/93] vs. 40.9% [61/149]; p < 0.001) and a numerically lower chest tube placement rate without significant reduction (4.3% [4/93] vs. 10.7% [16/149]; p = 0.126) with using normal saline instillation for sealing the needle track versus not using sealant material. Using a multiple logistic regression analysis, using normal saline instillation to seal the needle track, having a senior radiologist as operator of the procedure and putting patients in prone position were significantly associated with a decreased risk of pneumothorax. The presence of emphysema along the needle track was significantly associated with an increased risk of pneumothorax. No complication was observed due to normal saline injection. CONCLUSION:Normal saline solution instillation for sealing the needle track after computed tomography-guided percutaneous lung biopsy is a simple, low-cost and safe technique resulted in significantly decreased pneumothorax occurrence and a numerically lower chest tube placement rate, and might help to reduce both hospitalization risks and costs for the healthcare system.

[C-arm CT-guided 3D navigation of percutaneous interventions]. Becker H-C,Meissner O,Waggershauser T Der Radiologe So far C-arm CT images were predominantly used for a precise guidance of an endovascular or intra-arterial therapy. A novel combined 3D-navigation C-arm system now also allows cross-sectional and fluoroscopy controlled interventions. Studies have reported about successful CT-image guided navigation with C-arm systems in vertebroplasty. Insertion of the radiofrequency ablation probe is also conceivable for lung and liver tumors that had been labelled with lipiodol. In the future C-arm CT based navigation systems will probably allow simplified and safer complex interventions and simultaneously reduce radiation exposure. 10.1007/s00117-009-1866-3
Aspiration Pneumonia Caused by Prevotella Causing Prothorax after Pulmonary Puncture: a Case Report. Clinical laboratory BACKGROUND:Aspiration pneumonia in patients in immunocompetent populations is rare, and secondary pyothorax due to puncture operations during treatment has been reported rarely. METHODS:We report a confirmed case of aspiration pneumonia caused by Prevotella. The pathogen was detected and confirmed using percutaneous lung puncture and high-throughput next-generation sequencing (NGS). RESULTS:The patient developed secondary pyothorax, severe rash, and exacerbation of symptoms following the lung puncture. Finally, after adjusting the antibiotic regimen and performing chest drainage and washout, the patient's lesions were absorbed, symptoms improved, and the rash disappeared. CONCLUSIONS:Prevotella aspiration pneumonia can occur in immunocompetent individuals, and invasive bronchoscopic alveolar lavage may be considered as an option to reduce the risk of infectious organism translocation. 10.7754/Clin.Lab.2023.230605
Tumor seeding along the needle track after percutaneous lung biopsy. Valle Leonardo Guedes Moreira,Rocha Rafael Dahmer,Mendes Guilherme Falleiros,Succi José Ernesto,de Andrade Juliano Ribeiro Jornal brasileiro de pneumologia : publicacao oficial da Sociedade Brasileira de Pneumologia e Tisilogia 10.1590/S1806-37562016000000280
Pneumothorax after computed tomography-guided lung biopsy: Utility of immediate post-procedure computed tomography and one-hour delayed chest radiography. PloS one PURPOSE:To evaluate the utility of immediate post-procedure computed tomography (IPP-CT) and routine one-hour chest radiography (1HR-CXR) for detecting and managing pneumothorax in patients undergoing computed tomography (CT)-guided percutaneous lung biopsy. MATERIALS AND METHODS:All CT-guided percutaneous lung biopsies performed between May 2014 and August 2021 at a single institution were included. Data from 275 procedures performed on 267 patients (147 men; mean age: 63.5 ± 14.1 years; range 18-91 years) who underwent routine 1HR-CXR were reviewed. Incidences of pneumothorax and procedure-related complications on IPP-CT and 1HR-CXR were recorded. Associated variables, including tract embolization methods, needle diameter/type, access site, lesion size, needle tract distance, and number of biopsy samples obtained were analyzed and compared between groups with and without pneumothorax. RESULTS:Post-procedure complications included pneumothorax (30.9%, 85/275) and hemoptysis (0.7%, 2/275). Pneumothorax was detected on IPP-CT and 1HR-CXR in 89.4% (76/85) and 100% (85/85), respectively. A chest tube was placed in 4% (11/275) of the cases. In 3.3% (9/275) of the cases, delayed pneumothorax was detected only on 1HR-CXR, but no patient in this group necessitated chest tube placement. The incidence of pneumothorax was not significantly different between tract embolization methods (p = 0.36), needle diameters (p = 0.36) and types (p = 0.33), access sites (p = 0.07), and lesion sizes (p = 0.88). On logistic regression, a lower biopsy sample number (OR = 0.49) was a protective factor, but a longer needle tract distance (OR = 1.16) was a significant risk factor for pneumothorax. CONCLUSION:Following CT-guided percutaneous lung biopsy, pneumothorax detected on IPP-CT strongly indicates persistent pneumothorax on 1HR-CXR and possible chest tube placement. If no pneumothorax is identified on IPP-CT, follow-up 1HR-CXR may be required only for those who develop symptoms of pneumothorax. 10.1371/journal.pone.0284145
Diagnostic accuracy and complication rate of image-guided percutaneous transthoracic needle lung biopsy for subsolid pulmonary nodules: a systematic review and meta-analysis. The British journal of radiology OBJECTIVES:To determine the diagnostic accuracy and complication rate of percutaneous transthoracic needle biopsy (PTNB) for subsolid pulmonary nodules and sources of heterogeneity among reported results. METHODS:We searched PubMed, EMBASE, and Cochrane libraries (until November 7, 2020) for studies measuring the diagnostic accuracy of PTNB for subsolid pulmonary nodules. Pooled sensitivity and specificity of PTNB were calculated using a bivariate random-effects model. Bivariate meta-regression analyses were performed to identify sources of heterogeneity. Pooled overall and major complication rates were calculated. RESULTS:We included 744 biopsies from 685 patients (12 studies). The pooled sensitivity and specificity of PTNB for subsolid nodules were 90% (95% confidence interval [CI]: 85-94%) and 99% (95% CI: 92-100%), respectively. Mean age above 65 years was the only covariate significantly associated with higher sensitivity (93% vs  85%, = 0.04). Core needle biopsy showed marginally higher sensitivity than fine-needle aspiration (93% vs  83%, = 0.07). Pooled overall and major complication rate of PTNB were 43% (95% CI: 25-62%) and 0.1% (95% CI: 0-0.4%), respectively. Major complication rate was not different between fine-needle aspiration and core needle biopsy groups ( = 0.25). CONCLUSION:PTNB had acceptable performance and a low major complication rate in diagnosing subsolid pulmonary nodules. The only significant source of heterogeneity in reported sensitivities was a mean age above 65 years. ADVANCES IN KNOWLEDGE:This is the first meta-analysis attempting to systemically determine the cause of heterogeneity in the diagnostic accuracy and complication rate of PTNB for subsolid pulmonary nodules. 10.1259/bjr.20210065
Contralateral Dependent Position During Percutaneous CT-Guided Core Needle Biopsy for Small (≤ 20 mm) Lung Lesions Adjacent to the Pericardium: Effect on Procedures and Complications. Chen Chao,Xu Lichao,He Jia,Wang Ying,Wang Biao,Li Wentao,He Xinhong Cardiovascular and interventional radiology PURPOSE:To assess the effect of contralateral dependent position on procedures and complications of percutaneous computed tomography (CT)-guided core needle biopsy (PCT-CNB) for small (≤ 20 mm) lung lesions adjacent to the pericardium. MATERIALS AND METHODS:Retrospective view was performed to identify patients with small (≤ 20 mm) lung lesions located within 10 mm of the pericardium and who underwent PCT-CNB in the standard supine or prone position (n = 66) or in contralateral dependent position ( n = 35) between March 2010 and January 2020. In 35 patients, CT images in the contralateral dependent position were compared with images in the supine position to assess the mean distance of the lesion from the pericardium and the mean length of interface between these two positions. Complications including rates of pneumothorax, chest tube insertion, and pulmonary hemorrhage were assessed. RESULTS:In comparison with axial images in supine position, the pericardium were located farther from the lesion in the contralateral dependent position; the mean distance of lesions from the pericardium became farther (P < 0.001), and the mean length of interface with the pericardium became shorter (P = 0.008). There was no difference in the complication rates between supine or prone position and contralateral dependent position (pneumothorax, P = 0.098; pulmonary hemorrhage, P = 0.791). CONCLUSION:Placing patients in contralateral dependent position may confer some advantages, including maximizing distance and minimizing length of interface of the lesion to the pericardium during PCT-CNB for small (≤ 20 mm) lung lesions adjacent to the pericardium. 10.1007/s00270-020-02608-0
Risk Factors for Pneumothorax Development Following CT-Guided Core Lung Nodule Biopsy. Journal of bronchology & interventional pulmonology BACKGROUND:This study aims to correlate nodule, patient, and technical risk factors less commonly investigated in the literature with pneumothorax development during computed tomography-guided core needle lung nodule biopsy. PATIENTS AND METHODS:Retrospective data on 671 computed tomography-guided percutaneous core needle lung biopsies from 671 patients at a tertiary care center between March 2014 and August 2016. Univariate and multivariable logistic regression analyses were used to identify pneumothorax risk factors. RESULTS:The overall incidence of pneumothorax was 26.7% (n=179). Risk factors identified on univariate analysis include anterior [odds ratio (OR)=1.98; P<0.001] and lateral (OR=2.17; P=0.002) pleural surface puncture relative to posterior puncture, traversing more than one pleural surface with the biopsy needle (OR=2.35; P=0.06), patient positioning in supine (OR=2.01; P<0.001) and decubitus nodule side up (OR=2.54; P=0.001) orientation relative to decubitus nodule side down positioning, and presence of emphysema in the path of the biopsy needle (OR=3.32; P<0.001). In the multivariable analysis, the presence of emphysematous parenchyma in the path of the biopsy needle was correlated most strongly with increased odds of pneumothorax development (OR=3.03; P=0.0004). Increased body mass index (OR=0.95; P=0.001) and larger nodule width (cm; OR=0.74; P=0.02) were protective factors most strongly correlated with decreased odds of pneumothorax development. CONCLUSION:Emphysema in the needle biopsy path is most strongly associated with pneumothorax development. Increases in patient body mass index and width of the target lung nodule are most strongly associated with decreased odds of pneumothorax. 10.1097/LBR.0000000000000816
Benefit Over Risk Assessment of CT-guided Lung Core Needle Biopsy With the Coaxial Technique. In vivo (Athens, Greece) BACKGROUND/AIM:Lung percutaneous needle biopsy (PNB) under CT guidance can be performed with a single-needle or with a coaxial (CX) technique. This study evaluated the CX technique in a large cohort of patients who underwent to CT-guided lung PNB in our Institute over a period of 7 years. PATIENTS AND METHODS:We retrospectively collected and analyzed data relative to 700 CT-guided lung PNBs performed from August 2012 to August 2019 in 700 patients (M:F=436:264; mean age=69 years, range=6-93 years) with normal coagulation and pulmonary function. PNB was considered diagnostic if at least one of the collected tissue specimens allowed for histological diagnosis. Pulmonary hemorrhage (PH) and pneumothorax (PNX) were evaluated as present or absent. Statistical analysis was made by Chi-square test of Pearson, Fisher's exact test and Wilcoxon test. RESULTS:The CX technique showed a high diagnostic accuracy (93.0%) and allowed the collection of a great number of appropriate tissue specimens with a single pleural puncture (≥3 specimens in 77.4% of cases). PH was the complication more frequent (55.4%), without significant clinical impact. Global PNXs incidence was high (42.9%), but the introducer allowed to aspirate the PNX with a lower percentage of chest tube placement vs. PNXs not aspirated (6.3% and 13.3%, respectively). CONCLUSION:This large retrospective study confirmed the high diagnostic accuracy of lung PNB with the CX technique and allowed identification of significant factors to achieve a greater diagnostic power and decrease complication rates. 10.21873/invivo.13257
The effect of intraparenchymal blood patching on the rate of pneumothorax in patients undergoing percutaneous CT-guided core biopsy of the lung. Perl R M,Risse E,Hetzel J,Bösmüller H,Kloth C,Fritz J,Horger M European journal of radiology PURPOSE:To assess the effect of intraparenchymal blood patching (IBP) as well as tumor- and operator-related risk factors on the rate of pneumothoraxes after percutaneous CT-guided core needle biopsy of the lung. MATERIALS AND METHODS:We performed a retrospective analysis of 868 CT-guided lung biopsies that were conducted at our institution between 2003 and 2018, of which 419 (48%) received an IBP. Outcome variable included the rates of pneumothorax and chest tube placement, as well as lesion size (<3 cm versus ≥3 cm long axis diameter), lesion depth (≤2 cm, >2-4 cm, >4-5 cm and >5 cm distance to the pleura), location within the lungs (upper lobe, lower lobe, middle lobe), needle caliber (13 G, 15 G, 17 G, 19 G), number of samples taken (1-3 versus ≥4 samples), and experience of the performing physician. RESULTS:The rate of pneumothorax was significantly (p < 0.05) lower in the group with IBP (10.7%) compared to the group without IBP (15.4%). The number of post-interventional chest tube placements was also lower in the IBP group (3.1% vs. 5.8%) but not statistically significant. The lesion size correlated negatively with the rate of pneumothoraxes, whereas in both groups (±IBP) lesions ≥ 3 cm showed a significantly lower rate of pneumothorax (p < 0.05). With increasing lesion depth, the pneumothorax rate increased with (p < 0.01) and without (p < 0.001) IBP. The rate of pneumothorax was significantly lower (p < 0.05) for 17 G needles with IBP, but not for other calibers. For biopsies in the lower lobe, the pneumothorax rate reduced significantly (p < 0.001) with IBP. In case of ≥4 tissue samples, the pneumothorax rate was significantly lower with IBP (p < 0.01). For experienced operators, the overall pneumothorax rate was significantly lower compared to less experienced operators (p < 0001). CONCLUSIONS:IBP significantly reduces the rate of pneumothorax following CT-guided lung biopsies in particular for lesions located deeper in the lungs, when ≥4 samples are taken, when samples are taken by less-experienced operators, and when sampling from the lower lobes. 10.1016/j.ejrad.2019.04.010
CT-guided radiofrequency ablation for lung cancer. Matsuoka Toshiyuki,Okuma Tomohisa International journal of clinical oncology Recently, percutaneous radiofrequency (RF) ablation has been increasingly performed as a local treatment for lung malignancies. In RF ablation, the application of radiofrequency agitates ions in the tissues surrounding the electrode, causing them to fluctuate at high speed, and this generates frictional heat. The generated heat coagulates the tissues. Puncture is carried out under computed tomography (CT) guidance in the same manner as that for needle biopsy. In animal studies, it was speculated that air functioned as an insulator and that the heat did not damage normal surrounding lung parenchyma to any great extent, because lung is filled with air. An experimental VX2 tumor in rabbits was well controlled by RF ablation. Since the clinical use of RF ablation for lung malignancies was first reported in 2000, many series have been published. The patients reported in these studies were not candidates for surgical treatment, either because of poor cardiopulmonary function and comorbidities, or because they refused surgery. With RF ablation, complete necrosis can be expected for tumors with a diameter of 3 cm or less. Palliative RF ablation may be indicated for large tumors. The most frequent complication associated with puncture was pneumothorax, with a frequency higher for RF ablation compared with that for needle biopsy. The initial results have been promising, but we await future reports for long-term results. 10.1007/s10147-007-0665-y
CT-guided percutaneous transthoracic needle biopsy for paramediastinal and nonparamediastinal lung lesions: Diagnostic yield and complications in 1484 patients. Wang Ye,Jiang Faming,Tan Xiaobo,Tian Panwen Medicine Computed tomography-guided percutaneous transthoracic needle biopsy (PTNB) is used for identifying paramediastinal lung lesions that cannot be diagnosed by bronchoscopy, but the diagnostic performance and complication rate are unreported.This retrospective study was approved by the institutional review board committee. A total of 1484 patients who underwent PTNB between April 2012 and April 2015 were enrolled. The cohort was divided into a paramediastinal (n = 195) and a nonparamediastinal group (n = 1289) based on lesion location. Diagnostic yield for malignancy and complication rates were analyzed in both groups. Univariate and multivariate logistic regression analysis was used to determine independent risk factors for hemoptysis complication in the paramediastinal group.Percutaneous transthoracic needle biopsy showed 95.6% (109/114) sensitivity and 100% (77/77) specificity for the diagnosis of lesions in the paramediastinal group, with similar accuracy (95.4%, 186/195) to that in the nonparamediastinal group (94.7%, 1221/1289; P = 0.699). Compared with PTNB for nonparamediastinal lesions, PTNB for paramediastinal lesions demonstrated a comparable pneumothorax rate (8.21% vs 8.69%; P = 0.823) and hemothorax rate (2.56% vs 1.47%; P = 0.261), and a higher hemoptysis rate (28.2% vs 19.4%; P = 0.005). Among 6 defined paramediastinal regions, the overall complication rate was the highest in the posterior region (42.4%) and the lowest in the paraventricular region (13.6%). Multivariate analysis revealed that lesion size of 2 to 3 cm (odds ratio [OR] 3.22), intrapulmonary length of needle path >2 cm (OR 8.85), and proximal to pulmonary artery (OR 10.33) were independent risk factors for hemoptysis in the paramediastinal group.Computed tomography-guided PTNB can diagnose paramediastinal lesions with high yield and acceptable complication rates. Given higher rate of hemoptysis in PTNB for paramediastinal lesions, more attention should be paid in cases with high risks. 10.1097/MD.0000000000004460
Delayed cerebral air embolism complicating percutaneous needle biopsy of the lung. Shi Liuhong,Zhang Ruifeng,Wang Zhengyang,Zhou Pan The American journal of the medical sciences Computed tomography-guided percutaneous needle biopsy of the lung is a common and frequently performed procedure for diagnosis of lung lesions. However, this procedure is not without risks. The major complications include pneumothorax and hemoptysis, which are mild and self-limiting. The rare complications include air embolism, tension pneumothorax, pulmonary hemorrhage, and tumor dissemination, which are severe and life threatening. Cerebral air embolism is a very rare and fatal complication. In previous reports, cerebral air embolism generally occurred during or immediately after lung biopsy. Herein, we present the first case of cerebral infarction secondary to cerebral air embolism 6 hours after computed tomography-guided lung biopsy. 10.1097/MAJ.0b013e31827bbe23
Effectiveness of autologous blood injection in reducing the rate of pneumothorax after percutaneous lung core needle biopsy. Turgut Bekir,Duran Ferdane Melike,Bakdık Süleyman,Arslan Serdar,Tekin Ali Fuat,Esme Hıdır Diagnostic and interventional radiology (Ankara, Turkey) PURPOSE:To assess the effectiveness and safety of autologous intraparenchymal blood patch (IBP) application in reducing the frequency of pneumothorax (PTX) after percutaneous transthoracic pulmonary core needle biopsy. METHODS:The records of patients who underwent the transthoracic pulmonary core needle biopsy procedure under CT guidance between January 2015 and October 2018 were screened retrospectively. Patients whose traversed pulmonary parenchymal length was ≥20 mm during biopsy were included in the study irrespective of lesion size. The IBP procedure was made a department policy in November 2017; patients who underwent biopsy after this date comprised the IBP group, while those who underwent the procedure before this date comprised the control group. IBP recipients received 2-5 mL of autologous blood injection to the needle tract. Demographic data, procedural reports, tomography images, and the follow-up records of patients were assessed. RESULTS:A total of 262 patients were included in the study. Of the 91 patients that received an IBP, PTX developed in 13 (14.1%), with 7 (7.7%) requiring a thoracic tube. Of the 171 patients who did not receive an IBP, PTX developed in 45 (26.3%), with 19 (11.1%) requiring a thoracic tube. Patients who received an autologous IBP showed a significantly lower rate of PTX development versus those who did not (P = 0.01). Similarly, a significantly lower number of patients who received the blood patch required chest tube placement (P = 0.015). CONCLUSION:Autologous IBP is a safe, inexpensive and easy to use method that reduces the rate of PTX development and thoracic tube application after percutaneous core needle biopsies of the lung. 10.5152/dir.2020.19202
Incidence, risk factors, and prognostic indicators of symptomatic air embolism after percutaneous transthoracic lung biopsy: a systematic review and pooled analysis. Lee Jong Hyuk,Yoon Soon Ho,Hong Hyunsook,Rho Ji Young,Goo Jin Mo European radiology OBJECTIVES:To determine the incidence, risk factors, and prognostic indicators of symptomatic air embolism after percutaneous transthoracic lung biopsy (PTLB) by conducting a systematic review and pooled analysis. METHODS:We searched the EMBASE and OVID-MEDLINE databases to identify studies that dealt with air embolism after PTLB and had extractable outcomes. The incidence of air embolism was pooled using a random effects model, and the causes of heterogeneity were investigated. To analyze risk factors for symptomatic embolism and unfavorable outcomes, multivariate logistic regression analysis was performed. RESULTS:The pooled incidence of symptomatic air embolism after PTLB was 0.08% (95% confidence interval [CI], 0.048-0.128%; I = 45%). In the subgroup analysis and meta-regression, guidance modality and study size were found to explain the heterogeneity. Of the patients with symptomatic air embolism, 32.7% had unfavorable outcomes. The presence of an underlying disease (odds ratio [OR], 5.939; 95% CI, 1.029-34.279; p = 0.046), the use of a ≥ 19-gauge needle (OR, 10.046; 95% CI, 1.103-91.469; p = 0.041), and coronary or intracranial air embolism (OR, 19.871; 95% CI, 2.725-14.925; p = 0.003) were independent risk factors for symptomatic embolism. Unfavorable outcomes were independently associated with the use of aspiration biopsy rather than core biopsy (OR, 3.302; 95% CI, 1.149-9.492; p = 0.027) and location of the air embolism in the coronary arteries or intracranial spaces (OR = 5.173; 95% CI = 1.309-20.447; p = 0.019). CONCLUSION:The pooled incidence of symptomatic air embolism after PTLB was 0.08%, and one-third of cases had sequelae or died. Identifying whether coronary or intracranial emboli exist is crucial in suspected cases of air embolism after PTLB. KEY POINTS:• The pooled incidence of symptomatic air embolism after percutaneous transthoracic lung biopsy was 0.08%, and one-third of patients with symptomatic air embolism had sequelae or died. • The risk factors for symptomatic air embolism were the presence of an underlying disease, the use of a ≥ 19-gauge needle, and coronary or intracranial air embolism. • Sequelae and death in patients with symptomatic air embolism were associated with the use of aspiration biopsy and coronary or intracranial locations of the air embolism. 10.1007/s00330-020-07372-w
Diagnostic Ability of Percutaneous Needle Biopsy Immediately After Radiofrequency Ablation for Malignant Lung Tumors: An Initial Experience. Hasegawa Takaaki,Kondo Chiaki,Sato Yozo,Inaba Yoshitaka,Yamaura Hidekazu,Kato Mina,Murata Shinichi,Onoda Yui,Kuroda Hiroaki,Sakao Yukinori,Yatabe Yasushi Cardiovascular and interventional radiology PURPOSE:To evaluate the safety and diagnostic ability of percutaneous needle biopsy performed immediately after lung radiofrequency ablation (RFA). MATERIALS AND METHODS:From May 2013 to April 2014, percutaneous needle biopsy was performed immediately after RFA for 3 patients (2 men and 1 woman, aged 57-76 years) who had lung tumors measuring 1.3-2.6 cm in diameter. All patients had prior history of malignancy, and all tumors were radiologically diagnosed as malignant. Obtained specimens were pathologically classified using standard hematoxylin and eosin staining. RESULTS:We completed three planned sessions of RFA followed by percutaneous needle biopsy, all of which obtained tumor tissue that could be pathologically diagnosed. Two tumors were metastatic from renal clear cell carcinoma and rectal adenocarcinoma, respectively; one tumor was primary lung adenocarcinoma. There was no death or major complication related to the procedures. Although pneumothorax occurred in two patients, these resolved without the need for aspiration or chest tube placement. Tumor seeding was not observed, but 21 months after the procedure, one case developed local tumor progression that was treated by additional RFA. CONCLUSION:Pathologic diagnosis was possible by needle biopsy immediately after RFA for lung tumors. This technique may reduce the risks and efforts of performing biopsy and RFA on separate occasions. 10.1007/s00270-016-1324-3
Percutaneous core needle biopsy for small (≤ 10 mm) lung nodules: accurate diagnosis and complication rates. Jae Lee In,June Im Hyoung,Miyeon Yie,Kwanseop Lee,Yul Lee,Hoon Bae Sang Diagnostic and interventional radiology (Ankara, Turkey) PURPOSE:To evaluate accurate diagnosis and complication rates of percutaneous core needle biopsy (PCNB) with an automated gun for small lung nodules that are 10 mm or less in diameter. MATERIALS AND METHODS:Forty-two cases of small lung nodules with diameters ≤ 10 mm (mean diameter, 9 mm) that received a PCNB were included in this study. Imaging guidance was fluoroscopy in 30 cases and computed tomography (CT) in 12 cases. RESULTS:Accurate diagnosis was achieved with the initial PCNB in 88.1% (37/42) of cases. Accurate diagnosis rates were 86.7% (26/30) with fluoroscopic guidance and 91.7% (11/12) with CT guidance (P > 0.05). The complication rate of PCNB was 7.1% (3/42), including hemoptysis (n=2) and pneumothorax (n=1). The complication rate was 6.7% (2/30) with fluoroscopic guidance and 8.3% (1/12) with CT guidance (P > 0.05). CONCLUSION PCNB: with an automated gun is useful for the pathologically conclusive diagnosis of small lung nodules (≤ 10 mm in diameter) using fluoroscopic or CT guidance. 10.4261/1305-3825.DIR.5617-12.2
Nonfatal air embolism complicating percutaneous CT-guided lung biopsy and VATS marking: Four cases from a single institution. Yoshida Rika,Yoshizako Takeshi,Nakamura Megumi,Ando Shinji,Maruyama Mitsunari,Maruyama Minako,Takinami Yoshikazu,Tamaki Yukihisa,Nakamura Tomonori,Kitagaki Hajime Clinical imaging Systemic air emboli occur as a rare complication of percutaneous needle biopsy of the lung and video-assisted thoracoscopic surgery (VATS) marking. Here we present four cases of systemic air emboli from single institution and the imaging findings and embolism' kinetics using contrast-enhanced media during VATS color marking with indocyanine green. We suggest that early detection using routine whole-lung CT is required for asymptomatic patients with abnormal air. If abnormal air is found, we should keep the patient to the appropriate posture in order to prevent moving the air until it dissipates. Early detection of abnormal air can prevent severe complications. 10.1016/j.clinimag.2017.10.010
Fatal cardiac air embolism after CT-guided percutaneous needle lung biopsy: medical complication or medical malpractice? Forensic science, medicine, and pathology Computed tomography (CT)-guided percutaneous needle biopsy of the lung is a well-recognized and relatively safe diagnostic procedure for suspicious lung masses. Systemic air embolism (SAE) is a rare complication of transthoracic percutaneous lung biopsies. Herein, we present a case of an 81-year-old man who underwent CT-guided percutaneous needle biopsy of a suspicious nodule in the lower lobe of the right lung. Shortly after the procedure, the patient coughed up blood which prompted repeat CT imaging. He was found to have a massive cardiac air embolism. The patient became unresponsive and, despite resuscitation efforts, was pronounced dead. The pathophysiology, risk factors, clinical features, radiological evidence, and autopsy findings associated with SAE are discussed, which may, in light of the current literature, assist with the dilemma between assessing procedural complications and medical liability. Given the instances of SAE in the setting of long operative procedures despite careful technical execution, providing accurate and in-depth information, including procedure-related risks, even the rarest but potentially fatal ones, is recommended for informed consent to reduce medicolegal litigation issues. 10.1007/s12024-023-00639-w
Tract sealing with normal saline after percutaneous transthoracic lung biopsies - promising but better evidence required. Chan Michael Vinchill,Huo Ya Ruth,Lui Isaac,Ridley Lloyd Journal of medical imaging and radiation oncology 10.1111/1754-9485.13090
Computed Tomography-Guided Lung Biopsy: Does a Rural Hospital Do Better? Bar-Shai Amir,Brzezinski Rafael Y,Al Qaied Ahsen,Tsenter Philip,Kolontaevsky Svetlana,Breslavsky Anna The Israel Medical Association journal : IMAJ BACKGROUND:Lung percutaneous needle biopsy (PNB) is routinely used to diagnose lung cancer. The most prevalent complications of PNB are pneumothorax and bleeding. Differences in characteristics of medical procedures between rural and urban hospitals are well known. OBJECTIVES:To compare characteristics of patients and lesions between two hospitals and to evaluate whether lung PNB complications differ in rural vs. urban settings. METHODS:The authors examined case records of 561 patients who underwent lung biopsy at two different medical centers in Israel: Tel Aviv Sourasky Medical Center (urban) and Barzilai Medical Center (rural). To evaluate the complication rates, the authors analyzed findings from chest X-ray performed 2 hours after biopsy and computed tomography (CT) images at the site of biopsy. RESULTS:The study comprised 180 patients who underwent lung biopsy at Barzilai and 454 at Sourasky. The rate of pneumothorax did not differ between centers (12% at Barzilai and 19% at Sourasky, P = 0.08). Distance from pleura was positively correlated to pneumothorax occurrence in both centers; however, neither lesion size nor lesion locus was found to be a risk factor for pneumothorax. Mild bleeding at the biopsy site occurred equally at Barzilai and Sourasky (32% vs. 36%, P = 0.3, respectively). Furthermore, immediate CT post-biopsy at Barzilai showed 95% negative predictive value, showing that a CT scan performed immediately after lung biopsy cannot replace the routine follow-up chest X-ray in predicting iatrogenic pneumothorax. CONCLUSIONS:CT-guided percutaneous lung biopsies are comparable between rural and urban hospitals regarding procedure characteristics and complication rates.
Lung Needle Biopsy and Lung Ablation: Indications, Patient Management, and Postprocedure Imaging Findings. Clinics in chest medicine The clinical role and use of percutaneous transthoracic needle biopsy (TTNB) and ablation of lung tumors are evolving. Here we discuss important considerations for referring providers, including current and emerging indications supported by guidelines, critical aspects of pre and postprocedure patient management, and expected postprocedure imaging findings. 10.1016/j.ccm.2024.02.005
Pneumothoraxes after CT-guided percutaneous transthoracic needle aspiration biopsy of the lung: A single-center experience with 3426 patients. Tuberkuloz ve toraks Introduction:The purpose of this study is to determine how long patients who developed pneumothorax were followed up on in the emergency department, how many patients required chest tube placement, and what factors influenced the need for a chest tube in patients who underwent computed tomography (CT)-guided percutaneous transthoracic fine needle aspiration biopsy (PTFNAB). Materials and Methods:Patients who developed pneumothorax following CT-guided PTFNAB were analyzed retrospectively. In cases with pneumothorax, the relationship between chest tube placement and the size of the lesion, the lesion depth from the pleural surface, the presence of emphysema, and the needle entry angle were investigated. It was determined how long the patients were followed up in the emergency department, when a chest tube was placed, and when patients who did not require chest tube placement were discharged. Result:CT-guided PTFNAB was performed in 3426 patients within two years. Pneumothorax developed in 314 (9%) cases and a chest tube was placed in 117 (37%). The risk factor for chest tube placement was found to be the lesion depth from the pleural surface. The lesion depth from the pleural surface of >24 mm increased the risk of chest tube placement by 4.8 times. Chest tubes were placed at an average of five hours (5.04 ± 5.57). Conclusions:This study has shown that in cases with pneumothorax that required chest tube placement, the lesion depth from the pleural surface is a risk factor. Patients who developed pneumothorax on CT during the procedure had chest tubes placed after an average of five hours. 10.5578/tt.20239909
Pneumothorax with prolonged chest tube requirement after CT-guided percutaneous lung biopsy: incidence and risk factors. Moreland Anna,Novogrodsky Eitan,Brody Lynn,Durack Jeremy,Erinjeri Joseph,Getrajdman George,Solomon Stephen,Yarmohammadi Hooman,Maybody Majid European radiology PURPOSE:To evaluate the incidence and risk factors of pneumothoraces requiring prolonged maintenance of a chest tube following CT-guided percutaneous lung biopsy in a retrospective, single-centre case series. MATERIALS AND METHODS:All patients undergoing CT-guided percutaneous lung biopsies between June 2012 and May 2014 who required chest tube insertion for symptomatic or enlarging pneumothoraces were identified. Based on chest tube dwell time, patients were divided into two groups: short term (0-2 days) or prolonged (3 or more days). The following risk factors were stratified between groups: patient demographics, target lesion characteristics, and procedural/periprocedural technique and outcomes. RESULTS:A total of 2337 patients underwent lung biopsy; 543 developed pneumothorax (23.2 %), 187 required chest tube placement (8.0 %), and 55 required a chest tube for 3 days or more (2.9 % of all biopsies, 29.9 % of all chest tubes). The median chest tube dwell time for short-term and prolonged groups was 1.0 days and 4.7 days, respectively. The transfissural needle path predicted prolonged chest tube requirement (OR: 2.5; p = 0.023). Other factors were not significantly different between groups. CONCLUSION:Of patients undergoing CT-guided lung biopsy, 2.9 % required a chest tube for 3 or more days. Transfissural needle path during biopsy was a risk factor for prolonged chest tube requirement. KEY POINTS:• CT-guided percutaneous lung biopsy (CPLB) is an important method for diagnosing lung lesions • A total of 2.9 % of patients require a chest tube for ≥3 days following CPLB • Transfissural needle path is a risk factor for prolonged chest tube time. 10.1007/s00330-015-4200-7
Assessment of diagnostic accuracy and complication rates of CT-guided percutaneous core-needle biopsy for lung lesion: difference between solid and sub-solid nodules based on propensity score matching analysis. Clinical radiology AIM:To compare the success and complication rates of computed tomography (CT)-guided percutaneous core-needle biopsy (PCNB) based on the density of lung nodules, using propensity score matching (PSM). MATERIALS AND METHODS:This single-centre retrospective study included 1,312 PCNB cases of lung lesions, including solid (n=1,120), part-solid (n=115), and non-solid nodules (n=77), that were detected between March 2013 and March 2021. The diagnostic accuracy and complication rates of pneumothorax and pulmonary haemorrhage were analysed before PSM. To perform PSM, part-solid and non-solid nodules were combined and newly defined as sub-solid nodules. The diagnostic accuracy and complication rates of pneumothorax and pulmonary haemorrhage were then compared between solid and sub-solid nodules after PSM. RESULTS:Among the 1,312 included cases, the success rate and incidence of pneumothorax after CT-guided PCNB for solid, part-solid, and non-solid nodules were not statistically different (p=0.080 and 0.410). However, the rates of overall pulmonary haemorrhage showed statistical differences (p<0.001), particularly between solid and part-solid nodules (p<0.001) and between solid and non-solid nodules (p<0.001). After PSM, the incidence rates of overall pulmonary haemorrhage in solid and sub-solid nodules were 8.9% (17/192) and 29.7% (44/182), respectively, showing a statistically significant difference (p<0.001). CONCLUSION:There is increased risk of haemorrhage in CT-guided needle biopsy of sub-solid nodules compared to solid nodules. Increased emphasis should be placed on the risk of pulmonary haemorrhage when consenting these patients. 10.1016/j.crad.2023.04.012
Percutaneous CT-guided lung biopsy for the diagnosis of persistent pulmonary consolidation. Brioulet J,David A,Sagan C,Cellerin L,Frampas E,Morla O Diagnostic and interventional imaging PURPOSE:The primary objective of this study was to determine the diagnostic accuracy of percutaneous computed tomography (CT)-guided biopsy of persistent pulmonary consolidations. The secondary objective was to determine the complication rate and identify factors affecting diagnostic yield. MATERIALS AND METHODS:Two radiologists retrospectively reviewed 98 percutaneous CT-guided biopsies performed in 93 patients (60 men, 33 women; mean age, 62±14.0 (SD) years; range: 18-88 years) with persistent pulmonary consolidations. Final diagnoses were based on surgical outcomes or 12 months clinical follow-up findings. Biopsy results were compared to the final diagnosis to estimate diagnostic yield. RESULTS:A final diagnosis was obtained for all patients: 51/93 (54.8%) had malignant lesions, 12/93 (12.9%) specific definite benign lesions (including 9 infections, two pneumoconiosis and one lipoid pneumonia) and 30/93 (32.3%) non-specific benign lesions. CT-guided biopsy had an overall diagnostic yield of 60% (59/98) with a correct diagnosis for 50/51 malignant lesions (diagnostic yield of 98% for malignancy) and for 9/47 benign lesions (diagnostic yield of 19% for benign conditions). Major complications occurred in 4/98 (4%) of lung biopsies (four pneumothoraxes requiring chest tube placement). CONCLUSION:Percutaneous CT-guided biopsy is an alternative to endoscopic or surgical biopsy for the diagnosis of persistent consolidation with a low risk of severe complication. 10.1016/j.diii.2020.07.007
Cone-Beam CT-Guided Percutaneous Transthoracic Needle Lung Biopsy of Juxtaphrenic Lesions: Diagnostic Accuracy and Complications. Hong Wonju,Yoon Soon Ho,Goo Jin Mo,Park Chang Min Korean journal of radiology OBJECTIVE:To investigate the diagnostic accuracy and complications of cone-beam CT-guided percutaneous transthoracic needle biopsy (PTNB) of juxtaphrenic lesions and identify the risk factors for diagnostic failure and complications. MATERIALS AND METHODS:In total, 336 PTNB procedures for lung lesions (mean size ± standard deviation [SD], 4.3 ± 2.3 cm) abutting the diaphragm in 326 patients (189 male and 137 female; mean age ± SD, 65.2 ± 11.4 years) performed between January 2010 and December 2014 were included. The accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the PTNB procedures for the diagnosis of malignancy were measured based on the intention-to-diagnose principle. The risk factors for diagnostic failures and complications were evaluated using logistic regression analysis. RESULTS:The accuracy, sensitivity, specificity, PPV, and NPV were 92.7% (293/316), 91.3% (219/240), 91.4% (74/81), 96.9% (219/226), and 77.9% (74/95), respectively. There were 23 diagnostic failures (7.3%), and lesion sizes ≤ 2 cm ( = 0.045) were the only significant risk factors for diagnostic failure. Complications occurred in 98 cases (29.2%), including 89 cases of pneumothorax (26.5%) and 7 cases of hemoptysis (2.1%). The multivariable analysis showed that old age (> 65 years) ( = 0.002), lesion size of ≤ 2 cm ( = 0.003), emphysema ( = 0.006), and distance from the pleura to the target lesion (> 2 cm) ( = 0.010) were significant risk factors for complications. CONCLUSION:The diagnostic accuracy of cone-beam CT-guided PTNB of juxtaphrenic lesions for malignancy was fairly high, and the target lesion size was the only significant predictor of diagnostic failure. Complications of cone-beam CT-guided PTNB of juxtaphrenic lesions occurred at a reasonable rate. 10.3348/kjr.2020.1229
[The diagnostic value of CT-guided percutaneous needle lung biopsy in diffuse parenchymal lung diseases]. Peng Min,Xu Wen-bing,Shi Ju-hong,Cai Bai-qiang,Tian Xin-lun,Liu Tao,Zhang Hong,Xiao Yi,Liu Wei,Feng Rui-e,Liu Hong-rui,Zhu Yuan-jue Zhonghua jie he he hu xi za zhi = Zhonghua jiehe he huxi zazhi = Chinese journal of tuberculosis and respiratory diseases OBJECTIVE:This study was to evaluate the efficacy and limitation of CT-guided percutaneous cutting needle lung biopsy in the diagnosis of diffuse parenchymal lung diseases (DPLD). METHODS:A total of 481 patients admitted in Peking Union Medical College Hospital from January 2000 to December 2008 underwent CT-guided percutaneous cutting needle lung biopsy. The patients were evaluated by clinical history, physical examination and lung HRCT. Those with localized opacity or lesions in a single lung in the CT scan were excluded. Finally, 248 patients with DPLD in HRCT were enrolled for this study. RESULTS:The study patients included 114 males and 134 females, and the mean (± SD) age at diagnosis was 50 ± 16 (range from 13 - 78) years. Confirmed diagnosis by percutaneous needle lung biopsy was obtained in 130 patients (52.4%), including pulmonary infection (35.4%, 46/130), pulmonary malignant diseases (25.4%, 33/130), bronchiolitis obliterans organizing pneumonia/organizing pneumonia (22.3%, 29/130), pulmonary vasculitis (6.2%, 8/130), granulomatous lesions (4.6%, 6/130), pulmonary sarcoidosis (2.3%, 3/130), acute interstitial pneumonia (1.5%, 2/130), pulmonary amyloidosis (1.5%, 2/130), and pulmonary alveolar proteinosis (0.8%, 1/130). Open lung biopsy/video-assisted thoracoscopic surgery was performed in 37 out of 118 cases for which the diagnosis was undetermined by percutaneous lung biopsy. Confirmed diagnosis was obtained in 36 patients, including non-specific interstitial pneumonia (NSIP, 33.3%, 12/36), usual interstitial pneumonia (UIP, 8.3%, 3/36), pulmonary infection (16.7%, 6/36), neoplasm (8.3%, 3/36), lymphoid interstitial pneumonia, pulmonary vasculitis (5.6% 2/36), hypersensitivity pneumonitis (5.6%, 2/36), and pulmonary sarcoidosis, allergic bronchopulmonary aspergillosis, pulmonary hyalinizing granuloma, pneumoconiosis, Castleman's disease, and lymphoproliferative disorder (1 case respectively). CONCLUSION:CT-guided percutaneous cutting needle lung biopsy can provide confirmed diagnosis in half of patients with DPLD, and has a high diagnostic yield in patients with infectious or neoplastic diseases, but it is not a good method for diagnosis of interstitial lung diseases such as NSIP and UIP.
Patterns of percutaneous transthoracic needle biopsy (PTNB) of the lung and risk of PTNB-related severe pneumothorax: A nationwide population-based study. Yang Bo Ram,Kim Mi-Sook,Park Chang Min,Yoon Soon Ho,Chae Kum Ju,Lee Joongyub PloS one BACKGROUND:As percutaneous transthoracic needle biopsy (PTNB) of the lung is a well-established diagnostic method for the evaluating pulmonary lesions, evidence of safety based on representative data is limited. This study investigated the practice patterns of PTNB of the lung and assessed the incidence and risk factors of PTNB-related severe pneumothorax in Korea. METHODS:We used a national-level health insurance database between January 1, 2007 and December 31, 2015. Patients who underwent PTNB of the lung were identified using procedure codes for organ biopsy, fluoroscopy, computed tomography, chest radiography, and lung-related diagnosis codes. The annual age-/sex-standardized rate of PTNB and the incidence of PTNB-related severe pneumothorax were calculated. We defined severe pneumothorax as the pneumothorax requiring intervention. The odds ratios of risk factors were assessed by a generalized estimating equation model with exchangeable working correlation matrix to address clustering effect within institution. RESULTS:A total of 66,754 patients were identified between 2007 and 2015. The annual age-/sex-standardized rate of PTNB per 100,000 population was 19.6 in 2007 and 22.4 in 2015, and it showed an increasing trend. The incidence of severe pneumothorax was 2.4% overall: 2.5% in men and 1.2% in women, and 2.6%, 2.7%, 2.1%, 2.1%, 1.9%, 2.4%, and 2.4% from 2009 to 2015. Older age (≥60), male sex, presence of chronic obstructive pulmonary disease, receiving treatment in an urban or rural area versus a metropolitan area, and receiving treatment at a general hospital were significantly associated with the risk of severe pneumothorax. CONCLUSIONS:Considering the increasing trend of PTNB, more attention needs to be paid to patients with risk factors for severe pneumothorax. 10.1371/journal.pone.0235599
Usual Interstitial Pneumonia: Associations With Complications After Percutaneous Transthoracic Needle Lung Biopsy. AJR. American journal of roentgenology Changes in lung parenchyma elasticity in usual interstitial pneumonia (UIP) may increase the risk for complications after percutaneous transthoracic needle biopsy (PTNB) of the lung. The purpose of this article was to investigate the association of UIP findings on CT with complications after PTNB, including pneumothorax, pneumothorax requiring chest tube insertion, and hemoptysis. This retrospective single-center study included 4187 patients (mean age, 63.8 ± 11.9 [SD] years; 2513 men, 1674 women) who underwent PTNB between January 2010 and December 2015. Patients were categorized into a UIP group and non-UIP group by review of preprocedural CT. In the UIP group, procedural CT images were reviewed to assess for traversal of UIP findings by needle. Multivariable logistic regression analyses were performed to identify associations between the UIP group and needle traversal with postbiopsy complications, controlling for a range of patient, lesion, and procedural characteristics. The UIP and non-UIP groups included 148 and 4039 patients, respectively; in the UIP group, traversal of UIP findings by needle was observed in 53 patients and not observed in 95 patients. The UIP group, in comparison with the non-UIP group, had a higher frequency of pneumothorax (35.1% vs 17.9%, < .001) and pneumothorax requiring chest tube placement (6.1% vs 1.5%, = .001) and lower frequency of hemoptysis (2.0% vs 6.1%, = .03). In multivariable analyses, the UIP group with traversal of UIP findings by needle, relative to the non-UIP group, showed independent associations with pneumothorax (OR, 5.25; 95% CI, 2.94-9.37; < .001) and pneumothorax requiring chest tube placement (OR, 9.55; 95% CI, 3.74-24.38; < .001). The UIP group without traversal of UIP findings by needle, relative to the non-UIP group, was not independently associated with pneumothorax (OR, 1.18; 95% CI, 0.71-1.97; = .51) or pneumothorax requiring chest tube placement (OR, 1.08; 95% CI, 0.25-4.72; = .92). The UIP group, with or without traversal of UIP findings by needle, was not independently associated with hemoptysis. No patient experienced air embolism or procedure-related death. Needle traversal of UIP findings is a risk factor for pneumothorax and pneumothorax requiring chest tube placement after PTNB. When performing PTNB in patients with UIP, radiologists should plan a needle trajectory that does not traverse UIP findings, when possible. 10.2214/AJR.23.29938
Coaxial technique-promoted diagnostic accuracy of CT-guided percutaneous cutting needle biopsy for small and deep lung lesions. Zhang Lu,Shi Lei,Xiao Zhiping,Qiu Hong,Peng Ping,Zhang Mingsheng PloS one Coaxial technique is extensively applied to facilitate percutaneous lung lesion biopsy. However, the impact of coaxial technique on diagnostic accuracy remains undecided. We reviewed 485 patients who underwent percutaneous CT-guided needle biopsies of lung lesions in our hospital. All of these biopsies were performed using either a cutting needle alone (n = 268) or a cutting needle combined with a coaxial needle (n = 217). The diagnostic accuracy and complications resulting from the two techniques were then compared. The diagnostic accuracies of the two techniques were comparably high, at 98.2% (with coaxial technique) and 95.9% (without coaxial technique), p = 0.24. Subgroup analysis discovered that for patients with lesions measuring < 1.5 cm and needle path length ≥ 4 cm, the coaxial technique achieved a higher diagnostic accuracy (95.5% vs. 72.7%, p = 0.023). The biopsy was well tolerated in all of the patients. Pneumothorax occurred less often in patients who were biopsied with the coaxial technique (19 versus 43, p = 0.024). Thus, the application of the coaxial technique could improve diagnostic accuracy in patients with small and deep lung lesions, and could reduce the risk of pneumothorax. The combined use of cutting needles with coaxial needles is the preferred technique for performing percutaneous CT-guided lung biopsies. 10.1371/journal.pone.0192920
Lesion positioning method of a CT-guided surgical robotic system for minimally invasive percutaneous lung. Zhang Tie-Feng,Fu Zhuang,Wang Yao,Shi Wei-Yi,Chen Guang-Biao,Fei Jian The international journal of medical robotics + computer assisted surgery : MRCAS BACKGROUND:Robot-assisted puncture has gradually attracted more attention and practical clinical application. The lesion positioning and the needle positioning are the basis to ensure the accuracy of puncture and the key techniques in insertion operation. METHODS:A lesion positioning method is established which is realized only by the robot-CT system without using external positioning system, and an omnidirectional needle positioning method is also developed and realized by using VRCM, in order to make the puncture needle always keep pointing to the lesion point. A CT-guided surgical robotic system used for minimally invasive percutaneous lung is designed and the physical prototype is manufactured, to perform in-vitro experiments, thereby to validate the effectiveness of the lesion positioning method and the feasibility of omnidirectional needle positioning method. RESULTS:The accuracy of established lesion positioning method based on three non-collinear markers is within 3 mm, which is similar to that of the least squares method based on the five non-coplanar markers, but the positioning efficiency can be improved by about 40%, and the non-collinearity of markers is easier to be satisfied than non-coplanarity in practical applications. The average calculation error of the established positioning method is 0.997 mm. Moreover, the omnidirectional positioning of the puncture needle under the designed surgical robot is feasible. CONCLUSIONS:The designed surgical robot has good control accuracy and it can satisfy the requirements for use. The established lesion positioning method can provide a good precision basis for robot-assisted puncture surgery. The suitable insertion point and insertion posture can be determined by the developed omnidirectional needle positioning method. This study can provide theoretical reference for further study of path planning or autonomous positioning. 10.1002/rcs.2044
The Value of Computed Tomography-Guided Percutaneous Lung Biopsy Combined With Rapid On-Site Evaluation in Diagnosis of Peripheral Pulmonary Nodules. Technology in cancer research & treatment To investigate the value of computed tomography-guided percutaneous lung biopsy (CT-PLB) combined with rapid on-site evaluation (ROSE) in the diagnosis of peripheral pulmonary lesions (PPLs). A total of 108 patients who diagnosed with PPLs by chest CT examination were prospectively collected and randomly divided into ROSE group (n = 56) and No-ROSE group (n = 52). Both groups received CT-PLB and pathological examination. The smear submitted for ROSE was stained using Diff Quik dye. The accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), number of punctures, puncture time and incidence of complications were compared between the two groups. The accuracy, sensitivity, specificity, PPV, and NPV of the ROSE group were 89.29%, 87.50%, 91.67%, 93.33%, and 84.62%, respectively. The number of punctures in the ROSE group was significantly lower than that in the No-ROSE group ( < .05). The incidence of pneumothorax and hemoptysis in the ROSE group were lower than those in the No-ROSE group, but there was no statistical difference between the two groups ( > .05). ROSE has good concordance with routine pathological examination in the diagnosis of unidentified PPLs (Kappa = 0.786,  < .01). CT-PLB combined with ROSE is a safe and effective method for the diagnosis of PPLs. 10.1177/15330338221118718
Pneumothorax risk reduction during CT-guided lung biopsy - Effect of fluid application to the pleura before lung puncture and the gravitational effect of pleural pressure. European journal of radiology PURPOSE:This study investigated strategies to reduce pneumothorax risk in CT-guided lung biopsy. The approach involved administering 10 ml of 1 % lidocaine fluid in the subpleural or pleural space before lung puncture and utilizing the gravitational effect of pleural pressure with specific patient positioning. METHOD:We retrospectively analyzed 72 percutaneous CT-guided lung biopsies performed at a single center between January 2020 and April 2023. These were grouped based on fluid administration during the biopsy and whether the biopsies were conducted in dependent or non-dependent lung regions. Confounding factors like patient demographics, lesion characteristics, and procedural details were assessed. Patient characteristics and the occurrence of pneumothoraces were compared using a Kurskal-Wallis test for continuous variables and a Fisher's exact test for categorical variables. Multivariable logistic regression was used to identify potential confounders. RESULTS:Subpleural or pleural fluid administration and performing biopsies in dependent lung areas were significantly linked to lower peri-interventional pneumothorax incidence (n = 15; 65 % without fluid in non-dependent areas, n = 5; 42 % without fluid in dependent areas, n = 5; 36 % with fluid in non-dependent areas,n = 0; 0 % with fluid in dependent areas; p = .001). Even after adjusting for various factors, biopsy in dependent areas and fluid administration remained independently associated with reduced pneumothorax risk (OR 0.071, p<=.01 for lesions with fluid administration; OR 0.077, p = .016 for lesions in dependent areas). CONCLUSIONS:Pre-puncture fluid administration to the pleura and consideration of gravitational effects during patient positioning can effectively decrease pneumothorax occurrences in CT-guided lung biopsy. 10.1016/j.ejrad.2024.111529
Systemic Air Embolism Complicating Computed Tomography-guided Percutaneous Transthoracic Biopsy of Cavitary Lung Lesions: A Systematic Review. Roberts James M,Chou Frank Y,Byrne Danielle,Sedlic Anto,Mayo John R Journal of thoracic imaging PURPOSE:Cavitary lung lesions often pose a diagnostic challenge, and tissue sampling can be required to obtain a confident diagnosis. Many authors contend that a computed tomography-guided percutaneous transthoracic lung biopsy (PTLB) of a cavitary lung lesion places a patient at higher risk for systemic air embolism (SAE) compared with biopsy of a noncavitary lesion. MATERIALS AND METHODS:We reviewed the literature for studies of SAE complicating PTLB. We searched English-language articles indexed through PubMed, Embase, and Ovid Medline and included articles published up to March 31, 2020. RESULTS:We identified 10 case reports of SAE complicating PTLB, and 3 case-cohort studies comparing cavitary and noncavitary lesion biopsy. Among the case-cohort studies reviewed, 4 SAE occurred among 145 biopsies of cavitary lesions (2.7%), and 65 SAE occurred among 3050 biopsies of noncavitary lesions (2.1%). The pooled odds ratio of PTLB complicating SAE of cavitary lesions compared with noncavitary lesions was 1.29 (95% confidence interval: 0.47-3.60). No deaths following SAE after computed tomography-guided PTLB of cavitary lesions were reported in recent literature. CONCLUSIONS:On the basis of available evidence, air embolism rates are similar for PTLB of cavitary and noncavitary lesions. Additional research and registry studies are necessary to better understand this topic. 10.1097/RTI.0000000000000581
Utilization and Safety of Percutaneous Lung Biopsy: A 10-Year Nationwide Population-Based Study. Chen Chun-Ku,Chang Hsiao-Ting,Chen Yu-Chun,Chiang Shu-Chiung,Chou Hsiao-Ping,Chen Tzeng-Ji International journal of environmental research and public health Percutaneous lung biopsy is a technique used for sampling peripherally located lung masses and has been gaining in popularity. However, its exact utilization is unknown, and its safety has not been well studied. The current study aimed to assess the trend of utilization and study the safety of this procedure. Using the National Health Insurance Research Database, we retrospectively determined the total number of procedures that were performed on subjects older than 20 years between 2001 and 2010. We also estimated the rates of major complications, such as pneumothorax, requiring intercostal drainage. A total of 630 percutaneous biopsies were performed in 2001, while 3814 were performed in 2010, representing a 6.1-fold increase. The compound annual growth rate was 22.1%. The number of hospitals that performed the procedure increased from 55 to 99. Pneumothorax requiring drainage occurred in 1.5% of the procedures. The factors associated with a higher complication rate included male gender, chronic obstructive pulmonary disease, rural hospital, and low-volume hospital. Percutaneous lung biopsies are a relatively safe procedure, and their performance has been rapidly increasing. The number of procedures performed by a hospital was associated with the complication rate. 10.3390/ijerph16081316
Correlation between percutaneous transthoracic needle biopsy and recurrence in stage I lung cancer: a systematic review and meta-analysis. BMC pulmonary medicine BACKGROUND:To systematically evaluate the correlation between percutaneous transthoracic needle biopsy (PTNB) and recurrence in stage I lung cancer. METHODS:The databases of PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and China Biology Medicine disc were retrieved to collect relevant literatures about the correlation between PTNB and recurrence in stage I lung cancer. The retrieval time was limited from the time of their database establishment to April 30/2020.Screened the literature, extracted the data and assessed the quality of studies included. Then the meta-analysis was performed by using Stata l6.0 software. RESULTS:A total of 8 cohort studies involving 2760 lung cancer patients were included. The results of meta-analysis showed that PTNB did not increase the risk of total recurrence and pleural recurrence in the patients with stage I lung cancer. The result of subgroup analysis is according to the tumor location. For stage I lung cancer, PTNB will increase the risk of pleural recurrence in patients with sub-pleural lesions but not in those without sub-pleural lesions. CONCLUSIONS:To stage I lung cancer, PTNB is not associated with the total recurrence and pleural recurrence but PTNB will increase the risk of pleural recurrence in patients with sub-pleural lesions. 10.1186/s12890-020-01235-2
Complications and diagnostic accuracy of CT-guided 18G tru-cut versus end-cut percutaneous core needle biopsy of solitary solid lung nodules. Echevarria-Uraga José Javier,Del Cura-Allende Gorka,Armendariz-Tellitu Karmele,Berastegi-Santamaria Cristina,Egurrola-Izquierdo Mikel,Anton-Ladislao Ane Diagnostic and interventional radiology (Ankara, Turkey) PURPOSE:Percutaneous biopsy has demonstrated high accuracy in diagnosis of lung nodules, but the technique is not innocuous and a yield decrease in lesions smaller than 20 mm has been reported. We carried out a prospective study to evaluate and compare the complications and efficacy of percutaneous core needle biopsy (CNB) of solitary solid lung nodules, which were performed with two types of automatic guns. METHODS:330 consecutive CT-guided CNB were included. Tru-cut or end-cut 18G devices were used alternatively. Nodules were categorized by their size: ≤10 mm, 11-20 mm and >20 mm. Incidence of complications such as pneumothorax or hemoptysis and factors influencing them (nodule size and depth within lung parenchyma) were evaluated. Diagnostic accuracy of CNB achieved in the three groups of nodules regarding the two different needles were calculated and statistically evaluated and compared. RESULTS:We performed 68 CNB in nodules ≤10 mm, 130 in 11-20 mm and 132 in >20 mm. Pneumothorax appeared in 24.2% of them, but only 5.7% required drainage. Hemoptysis was developed in 9.4% and abundant hemoptysis with hypoxemia was observed in only 4.2% of patients. Regarding appearance of complications between the two needle types, no significant differences were found. A higher risk of hemoptysis was observed in nodules ≤10 mm (OR = 3.87; 95% CI = 1.24-12.06, P = 0.019) and in those located deeper in pulmonary parenchyma (OR = 2.21; 95% CI = 1.04-4.69, P = 0.038). End-cut needles reached a diagnostic accuracy of 93.7%, 92.1% and 98.3%, in nodules sized ≤10 mm, 11-20 mm and >20 mm, respectively. Corresponding results for tru-cut were 84.7%, 88.5% and 92.1%. In spite of differences reaching up to 9% in smaller nodules, intra-group results were not significant. CONCLUSION:Both needles have similar complications rate. Despite not having observed statistically significant differences between the two types of needles, end-cut devices have demonstrated a higher diagnostic yield in the three groups of nodules and could be a more suitable option especially for CNB of nodules ≤10 mm. 10.5152/DIR.2021.20462
Artificial Intelligence-Aided Selection of Needle Pathways: Proof-of-Concept in Percutaneous Lung Biopsies. Journal of vascular and interventional radiology : JVIR PURPOSE:To evaluate the concordance between lung biopsy puncture pathways determined by artificial intelligence (AI) and those determined by expert physicians. MATERIALS AND METHODS:An AI algorithm was created to choose optimal lung biopsy pathways based on segmented thoracic anatomy and emphysema in volumetric lung computed tomography (CT) scans combined with rules derived from the medical literature. The algorithm was validated using pathways generated from CT scans of randomly selected patients (n = 48) who had received percutaneous lung biopsies and had noncontrast CT scans of 1.25-mm thickness available in picture archiving and communication system (PACS) (n = 28, mean age, 68.4 years ± 9.2; 12 women, 16 men). The algorithm generated 5 potential pathways per scan, including the computer-selected best pathway and 4 random pathways (n = 140). Four experienced physicians rated each pathway on a 1-5 scale, where scores of 1-3 were considered safe and 4-5 were considered unsafe. Concordance between computer and physician ratings was assessed using Cohen's κ. RESULTS:The algorithm ratings were statistically equivalent to the physician ratings (safe vs unsafe: κ¯=0.73; ordinal scale: κ¯=0.62). The computer and physician ratings were identical in 57.9% (81/140) of cases and differed by a median of 0 points. All least-cost "best" pathways generated by the algorithm were considered safe by both computer and physicians (28/28) and were judged by physicians to be ideal or near ideal. CONCLUSIONS:AI-generated lung biopsy puncture paths were concordant with expert physician reviewers and considered safe. A prospective comparison between computer- and physician-selected puncture paths appears indicated in addition to expansion to other anatomic locations and procedures. 10.1016/j.jvir.2023.11.016
Factors influencing the total procedure time of CT-guided percutaneous core-needle biopsies of lung nodules: a retrospective analysis. Diagnostic and interventional radiology (Ankara, Turkey) PURPOSE This study aims to investigate the factors that influence total procedure time when performing computed tomography (CT)-guided percutaneous core-needle lung biopsies. METHODS This is a cross-sectional study of 673 patients, who underwent a CT-guided percutaneous coreneedle biopsy at a tertiary care center from March 2014 to August 2016. Data on patient, nodule, and procedural factors and outcomes were collected retrospectively. Univariate linear regression and a multivariate stepwise linear regression were utilized for analysis. RESULTS Factors most strongly associated with prolonged procedure duration include 20-gauge needle use when compared with 18-gauge needle use (estimated difference in time=1.19), collecting additional core biopsies (estimated difference in time=1.10), decubitus nodule side up (DNSU; estimated difference in time=1.42), and supine positioning (estimated difference in time=1.16) relative to decubitus nodule side down positioning, and increased nodule distance from the skin surface (estimated difference in time=1.03). Increased nodule length (estimated difference in time=0.93) was associated with reductions in procedure duration. Prolonged procedure time was associated with an increased rate of pneumothorax (odds ratio (OR)=1.02; P < .0001) and decreased rate of pulmonary hemorrhage (OR=0.97; P < .0001). CONCLUSION The use of 20-gauge biopsy needle, collecting additional core biopsies, DNSU and supine positioning, smaller nodule size, and increasing nodule distance from the skin surface were associated with increased procedure time for CT-guided core needle biopsies of lung nodules. Prolonged procedure time is associated with a higher rate of pneumothorax and a lower rate of pulmonary hemorrhage. 10.5152/dir.2022.20731
Interventional computed tomography. Murphy F B,Bernardino M E Current problems in diagnostic radiology Due to the development and refinement of computed tomography (CT), sonography, and interventional techniques, the field of interventional radiology has seen tremendous growth in recent years. In particular, the precise anatomic detail provided by CT and sonography has allowed percutaneous biopsies and abscess drainages to be performed safely and effectively. Percutaneous biopsies are now becoming the most common interventional radiographic procedures in many institutions. The usual indications for a biopsy are to determine the etiology of a mass, neoplasm, or inflammation, and to determine whether masses in known oncologic patients represent scarring or residual viable tumor. Accuracy rates for most percutaneous CT-directed biopsies are well over 90%, and the complication rate is very low. CT-directed percutaneous abscess drainages are also safe and effective and, in most cases, will be preferable to surgical drainage. The initial indications for percutaneous drainage (single, unilocular fluid collections) have been greatly expanded to include multiloculated collections, interloop abscesses, periappendiceal abscesses, and even percutaneous cholecystotomies. Biopsy and drainage procedures, together with their accuracy rates, indications and complications, are reviewed in this monograph. 10.1016/0363-0188(88)90004-7
Tract sealing with normal saline after percutaneous transthoracic lung biopsies. Babu Suresh B,Srinivasan Sivasubramanian,Chung Raymond,Chawla Ashish,Tan Hsien Khai,Lohan Rahul Journal of medical imaging and radiation oncology INTRODUCTION:In the present study, we aimed to assess whether normal saline injection for sealing the biopsy track is useful in reducing the incidence of pneumothorax after computed tomography (CT)-guided percutaneous transthoracic lung biopsy (PTLB). METHODS:We retrospectively compared the incidence of pneumothorax in 100 consecutive biopsies (n = 100, group A) that had injection of saline along the track, with historical cohort of same number of consecutive patients who underwent PTLB without injection of saline along the needle track (n = 100, group B). CT-guided biopsies were performed by coaxial technique and 1-3 ml of saline was injected along the tract. Patient chjmirocteristics, lesion size, location and other baseline pjmirometers were compared. Incidence of pneumothorax and number of patients who underwent catheter drainage of pneumothorax was compared in both groups. RESULTS:Baseline chjmirocteristics were compjmiroble in both groups. Track sealing with saline was successful in all patients. Pneumothorax rate was 46% for patients in group B and 32% in group A (P < 0.05). Seven patients (7%) had insertion of chest drain for pneumothorax in the group B and only 1% in the group A (P < 0.05). No mortality was observed in both groups. No complications were observed in any of the patients due to saline injection. CONCLUSION:Track sealing with saline is a simple and safe technique which significantly reduces the incidence of pneumothorax and chest tube insertion after PTLB. 10.1111/1754-9485.13002
Imaging-guided percutaneous transthoracic needle biopsy of nodules in the lung base: fluoroscopy CT versus cone-beam CT. Clinical radiology AIM:To compare the diagnostic performance and safety of fluoroscopy computed tomography (FCT)-guided to cone-beam CT (CBCT)-guided percutaneous transthoracic needle biopsy (PTNB) in patients with nodules in the lung base. MATERIALS AND METHODS:The clinical data of 379 patients (228 in the FCT group and 151 in the CBCT group) with nodules in the lung base who underwent FCT-guided or CBCT-guided PTNB from September 2009 to March 2020 were analysed retrospectively. Study outcomes included patient demographics, nodule characteristics, technical success, pathological diagnosis, complications, and radiation exposure. RESULTS:PTNB technical success rates were 98.2% in the FCT group and 98.7% in the CBCT group (p=0.548). For larger lesions (>2 cm in diameter), PTNBs under FCT had similar diagnostic accuracy (95.5% versus 93.64%), incidence of pneumothorax (31.5% versus 21.3%) and radiation exposure (16.8 ± 6.1 versus 15.2 ± 4 mSv) compared to those under CBCT guidance. For smaller lesions (≤2 cm in diameter), the diagnostic accuracy was similar (92.86% versus 100%), but there was a higher incidence of pneumothorax (66.7% versus 31%, p=0.030) and more radiation exposure (19.9 ± 8.4 versus 15.3 ± 5 mSv, p=0.040) under FCT guidance than CBCT. CONCLUSION:PTNBs under FCT and CBCT guidance had similar performance for larger lesions in lung base. CBCT guidance performed better for smaller lesions in terms of radiation dose and complications. Radiologists could optimise the technological resources based on equipment availability and lesion characteristics. 10.1016/j.crad.2022.02.005

Commentary on "Fatal cardiac air embolism after CT-guided percutaneous needle lung biopsy: medical complication or medical malpractice?" Forensic science, medicine, and pathology To differentiate between medical malpractice and expected, but rare, medical complication in a medicolegal autopsy context is often difficult. Such an assessment requires knowledge about the clinical practice associated with the procedure at hand, and that findings of the autopsy, including medical relevant information such as patient chart, radiological imaging, and statements from witnesses about the medical procedure itself, provides evidence that substantiate either conclusion. In a case report published in the journal such an assessment is discussed by presenting findings and circumstances surrounding the death of a patient during a percutaneous needle lung biopsy procedure. The authors conclude that the death was not due to medical malpractice. However, in this commentary it is highlighted that the reasoning behind the conclusion needs to be further substantiated. 10.1007/s12024-023-00667-6
Diagnostic accuracy and safety of CT-guided percutaneous lung biopsy with a coaxial cutting needle for the diagnosis of lung cancer in patients with UIP pattern. Scientific reports This study aimed to assess the diagnostic accuracy and safety of CT-guided percutaneous core needle biopsy (PCNB) with a coaxial needle for the diagnosis of lung cancer in patients with an usual interstitial pneumonia (UIP) pattern of interstitial lung disease. This study included 70 patients with UIP and suspected to have lung cancer. CT-guided PCNB was performed using a 20-gauge coaxial cutting needle. The diagnostic accuracy, sensitivity, specificity, and percentage of nondiagnostic results for PCNB were determined in comparison with the final diagnosis. PCNB-related complications were evaluated. Additionally, the risk factors for nondiagnostic results and pneumothorax were analyzed. The overall diagnostic accuracy, sensitivity, and specificity were 85.7%, 85.5%, and 87.5%, respectively. The percentage of nondiagnostic results was 18.6% (13/70). Two or less biopsy sampling was a risk factor for nondiagnostic results (p = 0.003). The overall complication rate was 35.7% (25/70), and pneumothorax developed in 22 patients (31.4%). A long transpulmonary needle path was a risk factor for the development of pneumothorax (p = 0.007). CT-guided PCNB using a coaxial needle is an effective method with reasonable accuracy and an acceptable complication rate for the diagnosis of lung cancer, even in patients with UIP. 10.1038/s41598-022-20030-z
Benign pathologies results from lung nodule percutaneous biopsies: How to differentiate true and false benign? Journal of cancer research and therapeutics OBJECTIVES:The objective was to identify predictors of true negatives in lung nodules (LNs) with computed tomography-guided percutaneous biopsy (CTPB)-based benign pathological results. MATERIALS AND METHODS:We included 90 total patients between January 2013 and December 2017 that had CTPB-based nonspecific benign pathologies and used these patients as a training group to accurately identify true-negative predictors. A validation group of 50 patients from January 2018 to June 2019 to confirm predictor reliability. RESULTS:CTPB was conducted on 90 LNs from the training group. True-negative and false-negative CTPB-based pathologies were obtained for 79 and 11 LNs, respectively. CTPB-based benign results had a negative predictive value of 87.8% (79/90). Univariate and multivariate analyses revealed younger age (P = 0.019) and CTPB-based chronic inflammation with fibroplasia (P = 0.010) to be true-negative predictors. A predictive model was made by combining these two prognostic values as follows: score = -7.975 + 0.112 × age -2.883 × CTPB-based chronic inflammation with fibroplasia (0: no present; 1: present). The area under receiver operator characteristic (ROC) curve was 0.854 (P < 0.001). To maximize sensitivity and specificity, we selected a cutoff risk score of -0.1759. The application of this model to the validation group yielded an area under the ROC curve of 0.912 (P < 0.001).

Percutaneous Lung Biopsy with Pleural and Parenchymal Blood Patching: Results and Complications from 1,112 Core Biopsies. Zlevor Annie M,Mauch Scott C,Knott Emily A,Pickhardt Perry J,Mankowski Gettle Lori,Mao Lu,Meyer Cristopher A,Hartung Michael P,Kim David H,Lubner Meghan G,Hinshaw J Louis,Foltz Marcia L,Ziemlewicz Timothy J,Lee Fred T Journal of vascular and interventional radiology : JVIR PURPOSE:To evaluate the outcomes of computed tomography (CT) fluoroscopy-guided core lung biopsies with emphasis on diagnostic yield, complications, and efficacy of parenchymal and pleural blood patching to avoid chest tube placement. METHODS:This is a single-center retrospective analysis of CT fluoroscopy-guided percutaneous core lung biopsies between 2006 and 2020. Parenchymal blood patching during introducer needle withdrawal was performed in 74% of cases as a preventive measure, and pleural blood patching was the primary salvage maneuver for symptomatic or growing pneumothorax in 60 of 83 (72.2%) applicable cases. RESULTS:A total of 1,029 patients underwent 1,112 biopsies (532 men; mean age, 66 years; 38.6%, history of emphysema; lesion size, 16.7 mm). The diagnostic yield was 93.6% (1,032/1,103). Fewer complications requiring intervention were observed in patients who underwent parenchymal blood patching (5.7% vs 14.2%, P < .001). Further intervention was required in 83 of 182 pneumothorax cases, which included the following: (a) pleural blood patch (5.4%, 60/1,112), (b) chest tube placement without a pleural blood patch attempt (1.5%, 17/1,112), and (c) simple aspiration (0.5%, 6/1,112). Pleural blood patch as monotherapy was successful in 83.3% (50/60) of cases without need for further intervention. The overall chest tube rate was 2.6% (29/1,112). Emphysema was the only significant risk factor for complications requiring intervention (P ≤ .001). CONCLUSIONS:Parenchymal blood patching during introducer needle withdrawal decreased complications requiring intervention. Salvage pleural blood patching reduced the frequency of chest tube placement for pneumothorax. 10.1016/j.jvir.2021.06.022
Percutaneous computed tomography-guided lung biopsy of solitary nodular ground-glass opacity. Zheng Yi-Feng,Jiang Li-Ming,Mao Wei-Min,Han Zhi-Qiang Journal of cancer research and therapeutics OBJECTIVE:To evaluate the diagnostic performance and safety of percutaneous lung biopsy under computed tomography (CT)-fluoroscopic guidance for ground-glass opacity (GGO) lesions. MATERIALS AND METHODS:Thirty-eight patients received core biopsy utilizing an automated cutting needle and were evaluated histologically. RESULTS:Five patients had a bronchioloalveolar carcinoma, 3 patients had adenocarcinomas, 18 patients had pulmonary alveoli epithelial dysplasia, 1 patient had a large number of lymphocytes, and 11 patients had a small amount of fibrous connective tissue. Twenty-three lesions (23/38, 60.5%) were located in the upper lobes while 15 lesions (15/38, 39.5%) were located in the lower lobes. Twenty-five lesions (25/38, 65.8%) were located in the right lung while 13 lesions (13/38, 34.2%) were located in the left lung. Three patients had pneumothorax, appeared on CT images performed immediately after the biopsy. Four patients had mild parenchymal hemorrhage along the needle tract or within the lesion. No patient required additional therapy such as a blood transfusion, endotracheal intubation, or chest tube placement after the biopsy. None of the patients had serious complications. CONCLUSION:Percutaneous CT-guided aspiration can be useful and safe diagnostic procedures for evaluating GGO nodules and a guidance to make a clinical decision for further patient management. 10.4103/0973-1482.162117
Preoperative percutaneous needle lung biopsy techniques and ipsilateral pleural recurrence in stage I lung cancer. Kim Min Gwan,Yang Bo Ram,Park Chang Min,Yoon Soon Ho European radiology OBJECTIVES:A recent meta-analysis of individual patient data revealed that preoperative percutaneous transthoracic needle lung biopsy (PTNB) was associated with an increased risk of ipsilateral pleural recurrence in stage I lung cancer. This study aimed to examine whether particular PTNB techniques reduced the risk of pleural recurrence. METHODS:We retrospectively included 415 consecutive patients with stage I lung cancer who underwent preoperative PTNB and curative resection from 2009 through 2016. Detailed information was collected, including clinical, PTNB technique, radiologic, and pathologic characteristics of lung cancer. Cox regression analyses were performed to identify risk factors for pleural recurrence before and after propensity score matching. RESULTS:The overall follow-up period after PTNB was 62.1 ± 23.0 months, and ipsilateral pleural recurrence occurred in 40 patients. Before propensity score matching, age (p = 0.063), microscopic pleural invasion (p = 0.065), and pathologic tumor size (p = 0.016) tended to be associated with pleural recurrence in univariate analyses and subsequently were matched using a propensity score. After propensity score matching, multivariate analysis revealed that ipsilateral pleural recurrence was associated with a larger target size on computed tomography (hazard ratio [HR] = 1.498; 95% CI, 1.506-2.125; p = 0.023) and microscopic lymphatic invasion (HR = 3.526; 95% CI, 1.491-8.341; p = 0.004). However, no PTNB techniques such as needle gauge, biopsy, or pleural passage numbers were associated with a reduced risk of recurrence. CONCLUSIONS:No particular PTNB techniques were associated with reduced pleural seeding after PTNB in stage I lung cancer. Regardless of the technique, PTNB needs to be cautiously applied when early lung cancer is suspected, followed by curative treatment. KEY POINTS:• Age, microscopic pleural invasion, and pathologic tumor size tended to be associated with pleural recurrence in stage I lung cancer before propensity matching. • After propensity matching, pre-biopsy CT target size and microscopic lymphatic invasion were associated with pleural recurrence. • No particular PTNB techniques were associated with reduced pleural seeding in stage I lung cancer before and after propensity matching. 10.1007/s00330-021-08359-x

Percutaneous Lung Biopsies With Robotic Systems: A Systematic Review of Available Clinical Solutions. Canadian Association of Radiologists journal = Journal l'Association canadienne des radiologistes This systematic review aims to assess existing research concerning the use of robotic systems to execute percutaneous lung biopsy. A systematic review was performed and identified 4 studies involving robotic systems used for lung biopsy. Outcomes assessed were operation time, radiation dose to patients and operators, technical success rate, diagnostic yield, and complication rate. One hundred and thirteen robot-guided percutaneous lung biopsies were included. Technical success and diagnostic yield were close to 100%, comparable to manual procedures. Technical accuracy, illustrated by needle positioning, showed less frequent needle adjustments in robotic guidance than in manual guidance ( < .001): 2.7 ± 2.6 (range 1-4) versus 6 ± 4 (range 2-12). Procedure time ranged from comparable to reduced by 35% on average (20.1 ± 11.3 minutes vs 31.4 ± 10.2 minutes, = .001) compared to manual procedures. Patient irradiation ranged from comparable to reduced by an average of 40% (324 ± 114.5 mGy vs 541.2 ± 446.8 mGy, = .001). There was no significant difference in reported complications between manual biopsy and biopsies that utilized robotic guidance. Robotic systems demonstrate promising results for percutaneous lung biopsy. These devices provide adequate accuracy in probe placement and could both reduce procedural duration and mitigate radiation exposure to patients and practitioners. However, this review underscores the need for larger, controlled trials to validate and extend these findings. 10.1177/08465371241242758
Image-Guided Percutaneous Lung Needle Biopsy: How we do it. Bourgouin Patrick P,Rodriguez Karen J,Fintelmann Florian J Techniques in vascular and interventional radiology Image-guided lung needle biopsy allows for minimally invasive diagnosis of lung pathology. In the setting of suspected malignancy, the biopsy not only confirms the diagnosis but also allows for molecular profiling, a requisite for tailored systemic therapy. Needle biopsy can also characterize non-neoplastic entities such as infections not responding to treatment and other inflammatory processes. A successful and safe lung needle biopsy starts with lesion and patient selection and careful pre-procedural evaluation. Here we review the indications and contraindications, diagnostic alternatives, approach planning and sequential procedural steps with the goal of maximizing both yield and patient safety. We discuss technical tips for preventing complications such as pleural anesthesia, the saline seal, the blood patch, the banana bend, hydro dissection, and the rapid needle out/patient rollover maneuver. We also review how to manage complications, avoid non-diagnostic biopsies, and provide recommendations for post-procedural observation and imaging follow-up. 10.1016/j.tvir.2021.100770
Path planning algorithm for percutaneous puncture lung mass biopsy procedure based on the multi-objective constraints and fuzzy optimization. Physics in medicine and biology . The percutaneous puncture lung mass biopsy procedure, which relies on preoperative CT (Computed Tomography) images, is considered the gold standard for determining the benign or malignant nature of lung masses. However, the traditional lung puncture procedure has several issues, including long operation times, a high probability of complications, and high exposure to CT radiation for the patient, as it relies heavily on the surgeon's clinical experience.To address these problems, a multi-constrained objective optimization model based on clinical criteria for the percutaneous puncture lung mass biopsy procedure has been proposed. Additionally, based on fuzzy optimization, a multidimensional spatial Pareto front algorithm has been developed for optimal path selection. The algorithm finds optimal paths, which are displayed on 3D images, and provides reference points for clinicians' surgical path planning.To evaluate the algorithm's performance, 25 data sets collected from the Second People's Hospital of Zigong were used for prospective and retrospective experiments. The results demonstrate that 92% of the optimal paths generated by the algorithm meet the clinicians' surgical needs.The algorithm proposed in this paper is innovative in the selection of mass target point, the integration of constraints based on clinical standards, and the utilization of multi-objective optimization algorithm. Comparison experiments have validated the better performance of the proposed algorithm. From a clinical standpoint, the algorithm proposed in this paper has a higher clinical feasibility of the proposed pathway than related studies, which reduces the dependency of the physician's expertise and clinical experience on pathway planning during the percutaneous puncture lung mass biopsy procedure. 10.1088/1361-6560/ad2c9f
Percutaneous Transthoracic Lung Biopsy: Optimizing Yield and Mitigating Risk. Azour Lea,Liu Shu,Washer Sophie L,Moore William H Journal of computer assisted tomography ABSTRACT:Percutaneous computed tomography-guided transthoracic lung biopsy is an effective and minimally invasive procedure to achieve tissue diagnosis. Radiologists are key in appropriate referral for further workup, with percutaneous computed tomography-guided transthoracic lung biopsy performed by both thoracic and general interventionalists. Percutaneous computed tomography-guided transthoracic lung biopsy is increasingly performed for both diagnostic and research purposes, including molecular analysis. Multiple patient, lesion, and technique-related variables influence diagnostic accuracy and complication rates. A comprehensive understanding of these factors aids in procedure planning and may serve to maximize diagnostic yield while minimizing complications, even in the most challenging scenarios. 10.1097/RCT.0000000000001192
