Abstract
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, p = 0.003], supine biopsy position (OR 7.06; 95% CI 2.24-22.21, p < 0.001), emphysema (OR 3.13; 95% CI 1.10-8.87, p = 0.028), greater needle depth ≥2 cm (OR 4.00; 95% CI 1.44-11.07, p = 0.005) and a larger pneumothorax (axial depth ≥3 cm) (OR 16.00; 95% CI 4.76-53.83, p < 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.

Abstract
Abstract
Background Pneumothorax is the most common complication of computed tomography (CT)-guided lung biopsy. The asymptomatic rate ranges from 17.5 to 72%. The symptomatic rate requiring chest tube insertion is 6 to 18%.
Aims This article studies the role of management of postbiopsy pneumothoraces by needle aspiration and pigtail catheter insertion.
Methods This was a prospective observational study conducted over 2 years. Postbiopsy and prior to withdrawing the coaxial cannula a CT data set was obtained to detect and quantify pneumothoraces as mild, moderate, and severe. In all asymptomatic cases of mild pneumothorax simple observation was done. In all asymptomatic cases of moderate pneumothorax, immediate needle aspiration was performed. In all symptomatic cases, cases with severe pneumothorax, and cases with progressively enlarging pneumothorax small caliber 6 to 8F pigtail catheters were inserted.
Results Ninety-one cases had mild pneumothorax, 42 had moderate pneumothorax, and 18 had severe pneumothorax. In the 91 patients of mild pneumothorax only 1 (1%) patient showed increase in size of pneumothorax on follow-up requiring catheter insertion. In the 42 cases of moderate pneumothorax, which were managed by simple aspiration of pneumothorax, 4 (9.5%) cases showed increase in size of pneumothorax on follow-up. A total 23 cases required pigtail catheter insertion in our study. These constituted 15.2% of pneumothorax cases. The mean duration of catheterization in our study was 3.74 ± 1.09 days.
Conclusion Majority of pneumothoraces are benign and do not require any intervention, just observation. Manual aspiration is an effective way of treating moderate pneumothoraces with success rate of 90%, thereby reducing the number of cases requiring catheter insertion; however, close observation is required as few cases may progress to severe pneumothorax and require pigtail insertion. Only a small percentage of biopsy cases (6.4%) require catheter insertion which is a safe and effective treatment.

Abstract
Percutaneous computed tomography (CT)-guided transthoracic needle biopsy (TTNB) is a valuable procedure for obtaining tissue or cells for diagnosis, which is especially indispensable in thoracic oncology. Pneumothorax and hemoptysis are the most common complications of percutaneous needle biopsy of the lung. According to reports published over the past decades, pneumothorax incidence in patients who underwent TTNB greatly varies. The morbidity of pneumothorax after CT-guided TTNB depends on several factors, including size and depth of lesions, emphysema, the number of pleural surfaces and fissure crossed, etc. Attention to biopsy planning and technique and post-biopsy precautions help to prevent or minimize potential complications. Many measures can be taken to help prevent the progression of a pneumothorax, which in turn might reduce the number of pneumothoraces requiring chest tube placement. A multitude of therapeutic options is available for the treatment of pneumothorax, varying from observation and oxygen treatment, simple manual aspiration, to chest tube placement. When a pneumothorax develops during the biopsy procedure, it can be manually aspirated after the needle is retracted back into the pleural space or by inserting a separate needle into the pleural space. Biopsy side down positioning of the patient after biopsy significantly reduces the incidence of pneumothorax and the requirement of chest tube placement. Aspiration in biopsy side down position is also recommended for treating pneumothorax when simple manual aspiration is unsuccessful or delayed pneumothorax occurred. Chest tube placement is an important treatment strategy for patients with a large or symptomatic pneumothorax. Clinicians are encouraged to understand the development, prevention, and treatment of pneumothorax. Efforts should be made to reduce the incidence of pneumothorax in biopsy planning and post-biopsy precautions. When pneumothorax occurs, appropriate treatment should be adopted to reduce the risk of worsening pneumothorax.

Abstract
Objective A central venous catheter (CVC) is often needed to treat hematologic diseases, but it is accompanied by many complications. Ultrasound guidance (USG) or a peripherally inserted central venous catheter (PICC) can reduce such complications. Meterials We collected data of patients with attempted CVC placement in our hematology unit in 2012 (before introduction of USG and PICC) and 2018 (after introduction) and compared both periods. Results In total, 187 CVC insertions were attempted in 2018 and 198 in 2012. USG was used 154 times (82%) in 2018 and 4 times (2%) in 2012 (p<0.001). The success rates of insertion were 95% in 2018 and 89% in 2012 (p=0.063). The incidence of acute complications was 4.3% in 2018 and 9.1% in 2012 (p=0.069). The incidence of CVC removal owing to delayed complications was 26% in 2018 and 21% in 2012 (p=0.327). The sites of approach in 2018 and 2012 were the internal jugular in 42 (22%) and 54 (27%), subclavian in 52 (28%) and 128 (65%), brachial (PICC) in 89 (48%) and 14 (7%), and femoral in 4 (2%) and 2 (1%), respectively (p<0.001). Conclusion USG has become commonplace since its introduction. The landmark-based subclavian approach was largely replaced by PICC with USG in 2018. USG and PICC can help improve success rates and safety profiles.

Abstract
BACKGROUND The goal of this study was to evaluate the efficacy of ipsilateral opposite-side aspiration, a new method to overcome resistant pneumothorax after failure of a simple aspiration. The patient position is reversed (from prone to supine or vice versa) and the aspiration repeated. METHODS Between January 1, 2010, and April 3, 2012, 129 consecutive, CT image-guided, percutaneous needle biopsies of lung nodules were performed in 127 patients (75 men, 52 women; mean age, 67.8 years; range, 26-88 years). Two patients underwent repeated biopsies. The mean lesion diameter was 38 mm (range, 8-110 mm). Core biopsy and fine-needle aspiration (FNA) were performed in 126 procedures; in three cases, only FNA was performed. In the cases with symptomatic minimal pneumothorax and in all patients with pneumothorax > 10 mm, immediate, simple, manual aspiration was performed. Ipsilateral opposite-side aspiration was performed when simple aspiration failed. RESULTS Among 129 CT image-guided biopsies, pneumothorax was detected by CT scan in 54 (42%); 51 (39%) were detected during the biopsy. Delayed pneumothorax occurred in two patients (1.55%). Manual aspiration to treat pneumothorax was performed in 27 of 129 procedures (21%). Simple aspiration was successful in 20 of these 27 cases (74%). Ipsilateral opposite-side aspiration was accomplished in the remaining seven cases (26%) and was successful in six cases (86%). Two of 129 procedures (1.55%) required chest tube placement. CONCLUSIONS Immediate, simple, percutaneous aspiration of iatrogenic pneumothorax was successful in 74% of patients needing treatment. Our proposed new method of ipsilateral opposite-side aspiration offers a solution for patients who remain with resistant pneumothorax after simple aspiration.

Abstract
OBJECTIVE The goal of our study was to evaluate the diagnostic performance of percutaneous lung biopsy under CT-fluoroscopic guidance for ground-glass opacity (GGO) lesions. METHODS 85 percutaneous needle lung biopsies were performed in 73 patients. Specimens were obtained by core biopsy utilising an automated cutting needle and were evaluated histologically. Final diagnosis was confirmed by independent surgical pathology, independent culture results or clinical follow-up. RESULTS Rates of adequate specimens obtained and of precise diagnosis by needle biopsy were 92.9% (79/85) and 90.6% (77/85) of evaluated lung lesions, respectively. Precise diagnosis was achieved in 87.1% (27/31) of lesions ≤10 mm in diameter, 90.0% (36/40) of lesions >10 mm to ≤20 mm and 100.0% (14/14) of lesions >20 mm. Precision in diagnosing GGO lesions according to the GGO component was 73.9% (17/23) for pure GGO lesions and 96.8% (60/62) for part-solid GGO lesions. Obtaining a precise diagnosis did not differ significantly according to the lesion size (p=0.3840), but differences were significant according to the GGO component (p=0.0047). Malignancy was accurately diagnosed in 35 of 36 malignant lesions for which surgery was later performed. The specific cell type determined from specimens obtained by needle biopsy was exactly the same as the final histological diagnosis obtained after surgery in 20 lesions. CONCLUSION Tissue-core lung biopsy under CT-fluoroscopic guidance for a GGO lesion provides a high degree of diagnostic accuracy but is less reliable for determining the specific cell type. ADVANCES IN KNOWLEDGE Percutaneous lung biopsy under CT-fluoroscopic guidance for GGO is useful in differentiating malignancy.

Abstract
Lung transplant recipients are among the patients most likely eventually to undergo diagnostic lung biopsy. Unfortunately, these patients are at particularly high risk for experiencing intra- and periprocedural complications. Percutaneous transthoracic needle biopsy (TNB) has over time emerged as an increasingly safe and reliable method of obtaining lung tissue for diagnosis. This article gives an overview of TNB including its indications, the imaging modalities currently used for guidance, and the special techniques utilized in performing the procedure and minimizing complications with an emphasis placed upon the special case of TNB performed in lung transplant recipients.

Abstract
Small peripheral pulmonary nodules continue to be a diagnostic challenge and because of improved technology are also being identified with increased frequency. TNB, performed properly, is a highly accurate procedure and with careful attention to technical factors, nodules of any size in any location may undergo biopsy. A skilled cytologist is an essential part of the team. Continued advances in molecular diagnostics allow for an expanded role of the usefulness of this procedure.

Abstract
PURPOSE The present study was performed to determine the frequency of the complication of pneumothorax after radiofrequency (RF) ablation for lung neoplasms and risk factors affecting such pneumothoraces. MATERIALS AND METHODS The study was based on 129 consecutive sessions of percutaneous RF ablation of lung neoplasms under real-time computed tomographic fluoroscopic guidance performed in a single institution between May 2003 and November 2005 in 41 patients (17 women, 24 men; mean age, 63 years; age range, 29-82 y). Correlation was determined between the incidence of pneumothorax after RF ablation and multiple factors: sex, age, presence of emphysema, lesion size, lesion depth, contact of tumor with pleura, number of punctures, maximum power of RF generator, period of ablation, tissue temperature at the end of the RF ablation session, and patient position during the procedure. Management of each case of iatrogenic pneumothorax was reviewed. RESULTS Pneumothorax after RF ablation occurred in 38 of 129 RF ablation sessions (29.5%). Fourteen of the 38 cases were treated by manual aspiration, and 24 were simply observed. In five cases (3.9%), chest tube placement was required as therapy for pneumothorax. The risk of pneumothorax was significantly increased in patients with pulmonary emphysema. CONCLUSIONS The frequency of pneumothorax after RF ablation in our experience is similar to the frequency of pneumothorax after lung biopsy reported in the literature. Various conditions for RF ablation did not influence the incidence of pneumothorax. Emphysema was the only individual factor that correlated significantly with the development of iatrogenic pneumothorax.

Abstract
The purpose of this study was to determine management guidelines for biopsy-induced pneumothorax with the assistance of manual aspiration, mainly based on the duration of complicated pneumothorax. Data from 388 consecutive percutaneous needle lung biopsies were examined. Patients with pneumothorax on postbiopsy chest CT images underwent percutaneous manual aspiration with an 18-G i.v. catheter. Frequency and management of biopsy-induced pneumothorax and period to its disappearance were reviewed. Postbiopsy pneumothorax occurred in 133 of 388 (34.3%) procedures. Manual aspiration in 72 of these 133 patients was carried out immediately after biopsy. The pneumothorax had resolved completely on follow-up chest radiographs without chest tube placement in 121 of the 133 pneumothoraces (91.0%). In cases requiring chest tube, the mean period from biopsy until resolution of the pneumothorax was 6.0 +/- 5.3 days, but was only 2.4 +/- 2.9 days when chest tube placement was not needed. Specifically, time until recovery was short both in those not requiring manual aspiration (2.1 +/- 3.4 days) and in those with a pneumothorax that disappeared completely or almost completely after manual aspiration (1.9 +/- 2.0 days). The almost equally short recovery periods in patients not requiring manual aspiration and those requiring immediate manual aspiration indicates the value of rapid management.

Abstract
The goal of this study was to evaluate the efficacy of simple aspiration of air from the pleural space to prevent increased pneumothorax and avoid chest tube placement in cases of pneumothorax following interventional radiological procedures performed under computed tomography fluoroscopic guidance with the transthoracic percutaneous approach. While still on the scanner table, 102 cases underwent percutaneous manual aspiration of a moderate or large pneumothorax that had developed during mediastinal, lung, and transthoracic liver biopsies and ablations of lung and hepatic tumors (independent of symptoms). Air was aspirated from the pleural space by an 18- or 20-gauge intravenous catheter attached to a three-way stopcock and 20- or 50-mL syringe. We evaluated the management of each such case during and after manual aspiration. In 87 of the 102 patients (85.3%), the pneumothorax had resolved completely on follow-up chest radiographs without chest tube placement, but chest tube placement was required in 15 patients. Requirement of chest tube insertion significantly increased in parallel with the increased volume of aspirated air. When receiver-operating characteristic curves were applied retrospectively, the optimal cutoff level of aspirated air on which to base a decision to abandon manual aspiration alone and resort to chest tube placement was 670 mL. Percutaneous manual aspiration of the pneumothorax performed immediately after the procedure might prevent progressive pneumothorax and eliminate the need for chest tube placement. However, when the amount of aspirated air is large (such as more than 670 mL), chest tube placement should be considered.

Abstract
PURPOSE The goal of this study was to evaluate the efficacy of simple aspiration of air from the pleural space to prevent increased pneumothorax and avoid chest tube placement in cases of pneumothorax after computed tomography (CT)-guided lung biopsy. MATERIALS AND METHODS This retrospective study was based on experience with 283 consecutive percutaneous needle lung biopsies with real-time CT fluoroscopic guidance. While patients were on the CT scanner table, percutaneous manual aspiration was performed in all those with moderate or large pneumothorax demonstrated on postbiopsy chest CT images regardless of symptoms. The authors evaluated the frequency of biopsy-induced pneumothorax, management of each such case, and factors that influenced the incidence of worsening pneumothorax that required chest tube placement despite manual aspiration. RESULTS Of the 104 (36.7%) pneumothoraces occurring after 283 biopsy procedures, 52 were treated with manual aspiration immediately after biopsy. In 95 of the 104 pneumothoraces (91.3%), the pneumothorax had resolved completely on follow-up chest radiographs without chest tube placement. Only nine patients (3.2% of the entire series; 8.7% of those who developed pneumothorax) required chest tube placement. Requirement of chest tube insertion significantly increased parallel to the increased volume of aspirated air. The optimal cutoff level of aspirated air on which to base a decision to abandon manual aspiration alone and resort to chest tube placement was 543 mL. CONCLUSION Percutaneous manual aspiration of biopsy-induced pneumothorax performed immediately after biopsy may prevent progressive pneumothorax and eliminate the need for chest tube placement. However, in cases in which the amount of aspirated air is large (such as more than 543 mL in this study), the possibility of required chest tube placement increases.

Abstract
OBJECTIVES The present study was performed to evaluate the efficacy and safety of gantry tilting for the performance of lung biopsy of peripheral small lesions located beneath the rib. DESIGN Interventional. MATERIALS AND METHODS Our study was based on 22 of 237 lesions for which percutaneous needle biopsies of the lung were performed under CT scan-fluoroscopic guidance at our institution between January 2000 and August 2002. For these 22 lesions, a biopsy was performed with gantry tilt because a rib blocked the biopsy route even after trials to change the relationship between the target and the rib. The characteristics of each lesion, the success rate for obtaining an adequate specimen, and the ability to determine whether the lesion was malignant or benign were investigated, specific cell types were characterized, and the complications that were encountered were identified. RESULTS In all 22 lesions, adequate specimens for cytopathologic evaluation were obtained using fine-needle aspiration biopsy, tissue core biopsies, or both. In 21 lesions, whether the lesion was malignant or benign was precisely diagnosed, and in 19 lesions the specific cell type was determined. No serious complications occurred. CONCLUSION Percutaneous needle biopsy under CT scan-fluoroscopic guidance with gantry tilt is a useful and safe technique for the biopsy of small lung nodules located beneath the rib.

Abstract
PURPOSE To evaluate the effect of coaxial needle size on pneumothorax rate and the diagnostic accuracy of computed tomography (CT)-guided transthoracic needle aspiration biopsy (TNAB) of pulmonary nodules. MATERIALS AND METHODS Retrospective review of 846 consecutive CT-guided TNAB procedures was performed. A coaxial approach was implemented in all patients by using an 18- or 19-gauge outer stabilizing needle through which a smaller aspiration needle or automated biopsy gun was inserted for tissue sampling. Univariate and multivariate regression analyses were used to analyze coaxial needle size, age, sex, smoking history, lesion size, use of an automated core biopsy gun, number of needle passes, and frequency of chest tube placement. Sensitivity, specificity, and diagnostic accuracy were calculated for 676 patients with at least 18 months of clinical follow-up. RESULTS Pneumothorax occurred in 226 of 846 patients. Coaxial needle size and patient age had a significant effect on pneumothorax rate. Pneumothorax occurred in 124 (38%) of 324 patients who underwent procedures with 18-gauge needles and in 121 (23%) of 522 patients who underwent procedures with 19-gauge needles (P <.001). The overall diagnostic accuracy was 96% for procedures performed with 18-gauge needles and 92% for procedures performed with 19-gauge needles, with a sensitivity of 95% and 89% and a specificity of 100% and 99%, respectively. Pneumothorax occurred in 153 patients older than 60 years, in 99 patients 60 years and younger (P <.02), in 90 patients older than 70 years, and in 162 patients younger than 70 years (P <.01). The relationship between pneumothorax rate and age as a continuous distribution was not significant (P <.07), nor were the 50- or 75-year age cutoffs (P <.06 and P <.9, respectively). CONCLUSION Use of a smaller coaxial stabilizing needle produces a substantially decreased risk of pneumothorax with comparable diagnostic accuracy, sensitivity, and specificity for histopathologic diagnosis of pulmonary nodules.

Abstract
PURPOSE To report our experience regarding the feasibility and safety of 25-gauge needles for biopsy of thoracic lesions. MATERIALS AND METHODS Twenty-six patients with thoracic lesions, predominately pulmonary nodules, measuring 0.7-5.2 cm (mean, 1.6 cm) underwent biopsy with computed tomographic (n = 24), ultrasonographic (n = 1), or fluoroscopic (n = 1) guidance. Nineteen patients had severe chronic obstructive pulmonary disease (COPD), one had severe restrictive lung disease, and one had a coagulopathy; the other five patients had nonpulmonary primary tumors. Biopsy with an inner 25-gauge needle traversing an outer extrapleural coaxial cannula was performed in all patients. Cytologic quick staining was performed routinely to determine specimen adequacy and to establish a preliminary diagnosis. Complications, specimen adequacy, and need for larger specimens were evaluated. RESULTS Adequate specimens (as determined by cytopathologists) were obtained in 24 (92%) of 26 patients, with a definitive diagnosis achieved in 23 (88%) patients during initial quick staining (17 malignant and six benign diagnoses). Two cases initially considered suspicious for malignancy were reclassified as benign (thymoma and histoplasmosis). At the request of cytopathologists, a larger needle was used to supplement the 25-gauge needle in six patients: In one patient, it provided further diagnostic information; in four, it did not; and in one, it confirmed non-Hodgkin lymphoma. Five patients developed a small pneumothorax (<10%) with use of the 25-gauge needle alone; one other patient, in whom larger needles were placed, received a radiologic chest catheter to evacuate the pneumothorax, thereby allowing the biopsy to continue. CONCLUSION Image-guided 25-gauge needle biopsy is both feasible and safe.

Abstract
Transthoracic needle biopsy (TNB) is usually avoided in the presence of pneumothorax. The authors performed computed tomography (CT)-guided transthoracic core biopsy in the presence of pneumothorax in 13 patients (4.9%) selected from 265 patients who received CT-guided TNB over 4 years. These iatrogenic pneumothoraces were induced by previous ultrasound (US)-guided TNB (n = 5), transbronchial lung biopsy (n = 4), and CT-guided biopsy (n = 4). The time interval between previous thoracic intervention and CT-guided TNB ranged from 0 hours to 9 days after transbronchial lung biopsy (average, 4 days). A diagnostic core biopsy was performed in 12 of the 13 patients. Seven lesions proved to be malignant and five were benign. Failure of CT-guided transthoracic core biopsy occurred in a single patient with a previous US-guided biopsy within 24 hours. This patients demonstrated a progressively enlarging pneumothorax and was treated with air aspiration with CT guidance. A successful second biopsy was performed 7 days later after full expansion of the lung. There were no complications related to the procedures. The authors' experience suggests that CT-guided transthoracic core biopsy using small-bore coaxial technique can be safely performed with high-diagnostic yield in patients with stable iatrogenic pneumothorax.

Abstract
This review discusses real-time pulmonary ultrasonography (US) for the practicing pulmonologist. US supplements chest radiography and chest CT scanning. Major advantages include bedside availability, absence of radiation, and guided aspiration of fluid-filled areas and solid tumors. Pulmonary vessels and vascular supply of consolidations may be visualized without contrast. US may help to diagnose conditions such as pneumothorax, hemothorax, pleural or pericardial effusion, pneumonia, and pulmonary embolism in the critically ill patient who is in need of bedside diagnostic testing. The technique of US, which is cost-effective compared to CT scanning and MRI, may be learned relatively easily by the pulmonologist.

Abstract
OBJECTIVES To evaluate the efficacy of simple aspiration of air from the pleural space to prevent increased pneumothorax and to avoid chest tube placement in cases of pneumothorax following CT-guided lung biopsy. DESIGN Observational. MATERIALS AND METHODS One hundred thirty-four consecutive percutaneous needle lung biopsies using real-time CT fluoroscopy guidance formed the basis of our study. All patients that demonstrated moderate or severe pneumothorax on postbiopsy chest CT images underwent percutaneous manual aspiration regardless of symptoms while on the CT scanner table. Correlation between the incidence of pneumothorax after biopsy and many factors (i.e., gender, age, number of pleural passes, presence of emphysema, lesion size, and lesion depth) were determined, and management of each case of biopsy-induced pneumothorax was reviewed. RESULTS Postbiopsy pneumothorax occurred in 46 of 134 procedures (34.3%). Twenty of the 46 patients were treated by manual aspiration, while 26 patients were simply observed. In 43 of the 46 pneumothoraces (93.5%), the pneumothorax resolved completely on follow-up chest radiographs without requiring tube placement. Only three patients (2.2% of the entire series; 6.5% of those who had pneumothorax develop) required chest tube placement. The risk of pneumothorax significantly increased with lesion size and depth. CONCLUSION Results of our nonprospective, nonrandomized study suggest that percutaneous manual aspiration of biopsy-induced pneumothorax performed immediately after biopsy may prevent progressive pneumothorax and subsequent chest tube placement.

Abstract
Lung cancer is the leading cause of cancer deaths in the United States. The individual therapeutic approach and prognosis depends on accurate diagnosis and staging. Flexible bronchoscopy (FB) and transthoracic needle biopsy (TNB) are the most widely used techniques for this purpose. This article provides a critical overview of indications, diagnostic yield, and limitations of bronchoscopy and TNB in the diagnosis of lung cancer.

Abstract
PURPOSE To evaluate risk factors for pneumothorax and bleeding after computed tomography (CT)-guided percutaneous coaxial cutting needle biopsy of lung lesions. MATERIALS AND METHODS This study involved 117 consecutive patients with 117 intrapulmonary lesions. Statistical analysis of factors related to patient characteristics, lung lesions, and biopsy technique was performed to determine possible contribution to the occurrence of pneumothorax and bleeding. Interactions between related factors were considered to prevent colinearity. RESULTS Pneumothorax occurred in 12% (14 of 117) of patients. Needle aspiration of two moderate asymptomatic pneumothoraces were performed; there was no chest tube insertion. Lesion depth (P =.0097), measured from the pleural puncture site to the edge of the intrapulmonary lesion along the needle path, was the single significant predictor of pneumothorax. The highest risk of pneumothorax occurred in subpleural lesions 2 cm or shorter in depth (this represented 33% of lung lesions but caused 71% of all pneumothoraces; OR = 7.1; 95% CI, 1.3-50.8). Bleeding presented as lung parenchyma hemorrhage and hemoptysis in 30 patients (26%). Hemoptysis occurred in four patients (3%). Univariate analysis identified lesion depth (P <.0001), lesion size (P <.015), and pathology type (P =.007) as risk factors for bleeding. Multivariate logistic regression analysis identified lesion depth as the most important risk factor, with the highest bleeding risk for lesions more than 2 cm deep (14% of lesions caused 46% of all bleeding; OR = 17.3; 95% CI, 3.3-121.4). CONCLUSIONS In CT-guided coaxial cutting needle biopsy, lesion depth is the single predictor for risk of pneumothorax, which occurs at the highest rate in subpleural lesions. Increased risk of bleeding occurs in lesions deeper than 2 cm.

Abstract
PTNB is a well-established technique for the diagnosis of lung cancer. In recent years, CT guidance has become the primary imaging modality, replacing fluoroscopy guided biopsies in many institutions. CT fluoroscopy, which is currently not universally available, offers promising advantages and may permit accurate and rapid procedures. A recent innovation in biopsy needles has been the introduction of automatic core biopsy needle devices that yield large specimens and improve the diagnostic accuracy of needle biopsy, particularly in benign lesions. PTNB is one of several methods available for tissue diagnosis of suspected lung cancer. The decision as to which method to use should be tailored to each patient, and is preferably reached by a team consisting of pulmonary physicians, chest surgeons, oncologists, cytologists, and radiologists.

Abstract
We believe that each aspect of the performance of TNB needs to be considered carefully. Meticulous attention to detail allows any nodule in the chest to successfully undergo biopsy. There are techniques of needle tip repositioning that can be quite helpful for obtaining diagnostic material from lung lesions, particularly small nodules. A strong working relationship with pathologists experienced in lung cytology is a vital element of any successful biopsy program. Techniques available to the pathologist allow for quick and decisive determination of the adequacy of the aspirated specimen and help guide the radiologist performing the procedure. Newer cytopathologic techniques help the pathologist make more complex diagnoses from the aspirated material. Finally, techniques used to minimize complications should be considered by the operator before the performance of the biopsy.

Abstract
Transthoracic needle biopsy (TNB) has emerged as the semi-invasive technique of choice for the diagnosis of localized intrathoracic lesions. Using CT, fluoroscopic, or sonographic guidance, TNB is highly accurate and safe when combined with expert pathologic interpretation of the aspirated specimen. This article details the preprocedural evaluation of the patient referred for TNB and discusses the technical aspects of performing the biopsy and processing and interpreting the material obtained. The reported results and complications of TNB are reviewed and followed by a brief description of the cost effectiveness of the technique and a comparison with alternative semi-invasive diagnostic techniques including bronchoscopic and video-assisted thoracoscopic biopsy.

Abstract
Transthoracic needle biopsy (TNB) has become the diagnostic procedure of choice in evaluation of focal chest lesions. Both advances in cross-sectional image guidance and cytopathologic techniques allow TNB to accurately diagnose malignancy and characterize a spectrum of benign conditions. Image-guided percutaneous drainage of intrathoracic collections has developed as an extension of similar procedures in the abdomen and pelvis. The ability of CT and ultrasound to accurately detect and characterize parenchymal and pleural collections, and advances in interventional techniques and catheter design, have made percutaneous catheter drainage the treatment of choice for a variety of intrathoracic collections. This article provides an updated review of the spectrum of image-guided diagnostic and therapeutic procedures in the thorax.
