Pneumothorax and pulmonary hemorrhage frequency and risk factors of computed tomography-guided transthoracic pulmonary biopsy complications

Introduction: We aimed to analyze the frequency and risk factors of pneumothorax pulmonary hemorrhage caused by Computed Tomography (CT) guided needle biopsy. Methods: Demographical features, frequencies/risk factors, characteristics lesions patients who underwent a CT-guided lung biopsy in our institution between January 2013 August were reviewed retrospectively. The classified groups as nodular lesions≤3 cm diameter, lesions>3 consolidated lesions. Pneumothorax frequencies among compared using chi-square test. A p<0.05 was accepted statistically significant. Results: total number 122 with mean age 61±13 (19-88) years included. 28 (23%) female 94 (77%) male. 30 (24%) 57 (47%) cm, 35 (29%) developed 15 (12%) while chest tube insertion required 4 (3%) them. Pulmonary occurred 14 (11%) patients. Hemoptysis hemothorax not observed this study. Pleura-based significantly less associated when ones far from pleura (P<0.001). Usage 17-gauge more than 19-gauge (p:0.048). during than<3 Conclusion: Nodular location usage tend be frequent complications.
