We reviewed the pathology results of 150 biopsy specimens obtained fromthe cases, and assessed the effect of lesion size, depth, patient age and patient emphysema on pneumothorax rate.Results: Lesion size ranged 1-18 cm (mean 6.5+3.4 cm). 95 lesions had zero distance from the chest wall, which were alltaken into account in our calculations.Pneumothorax rate was 6 percent, and we found that lesion depth (p <0.05), lesion size(p=0.069), patient age (p=0.058,) and presence of emphysema (p <0.001) are significantly associated with increasingpneumothorax rate (CI=90%).Conclusion: Lesion depth, lesion size, patient age, and emphysema significantly increase the rate of pneumothorax duringtransthoracic CT-guided needle biopsy.(Tanaffos 2002;1(1):15-21)}, keywords = {CT-guided needle biopsy,Complications,Pneumothorax,Emphysema}, url = {https://www.tanaffosjournal.ir/article_241905.html}, eprint = {https://www.tanaffosjournal.ir/article_241905_65f1073123fd58358bb0320e2381c396.pdf} }
