Abstract:

Purpose: The purpose of this study is to determine the diagnostic accuracy, the complication rates and the factors affecting the complications of computed tomography (CT) guided percutaneous transthoracic lung biopsy (PTB). Materials and Methods: We retrospectively evaluated 153 patients who underwent transthoracic CT-guided biopsy. Re-biopsy were performed in 10 patients so that 163 transthoracic CT-guided biopsy were included in this study. Results: Diagnostic results were achieved in 142 of 163 biopsy procedure (87.1%). During or after a biopsy procedure pneumothorax, parenchymal hemorrhage and hemoptysis were developed in 30 (18.4%), 21 (12.8%) and 2 (1.2%) patients respectively. A significant relationship was found between development of pneumothorax with the age of patient, the necrosis inclusion of the lesion, the size of the lesion and the parenchymal distance that was passed. There was a statistically significant correlation between parenchymal hemorrhage with the size of the lesion and the passed parenchymal distance. Conclusion: Computed tomography-guided PTB is a reliable method that reduces the need of invasive surgical procedures with high accuracy and low complication rates in the histopathological diagnosis of thoracic masses.
