Özet

Objective: In our study, we aimed to evaluate the relationship of various factors with complications that may develop, especially pneumothorax, in transthoracic fine needle aspiration biopsies (FNAB) performed under computed tomography (CT) guidance. Material and Methods: This retrospective study reviewed lung biopsy results of 114 patients who underwent 120 FNABs with repeated procedures performed between January 2015 and July 2015. Information about the lesion, distances and pathologies passed in the biopsy tract, patient position, information about the needle entry and developing complications were evaluated and the findings were recorded. Results: During and after the procedure 37 patients (30.8%) developed parenchymal hemorrhage and 22 patients (18.3%) developed pneumothorax complications. 5 of patients with pneumothorax (4.2%) were treated with pleural drainage. There was a significant correlation between development of pneumothorax and traversed parenchymal distance (p=0.008), traversed total distance (p=0.001), presence of fissure or emphysematous parenchyma in the needle tract (p=0.001) and patient position (p=0.001). Conclusion: To minimize the risk of complications during FNAB, we recommend to avoid from lateral decubitus position and emphysematous parencyhma and fissures in the needle tract. We also recommend to prefer the shortest needle tract length.
