Abstract
This study investigates factors influencing the risk of pneumothorax and chest tube placement in patients undergoing CT-guided transthoracic lung biopsy for pulmonary lesions using a coaxial technique.The study included 307 patients with pulmonary lesions biopsied under CT guidance. Patient-related parameters considered were age, sex, presence of emphysema or bullae, and lung function data. Lesion-related variables were size, location, cavitary appearance on CT, pleural contact, and depth of the lesion. Procedure variables were duration, type of needle, and experience of the operator. All variables were analyzed as single and multiple dependent variables for occurrence of pneumothorax.Pneumothorax occurred in 61 (19.9%) of the 307 patients, and chest tube placement was required in six patients (2.0%). Univariate analysis showed that lesion size, lesion location, lesion depth, and difficulty of the procedure were significantly associated with a higher rate of pneumothorax. Using multivariate logistic regre...Keywords
