Objective: The aim of this study is to present the our experience of transthoracic biopsy.

Materials and Method: Transthoracic biopsy were performed in 452 cases (54 female, 398 male) in our interventional radiology unit between 01.01.2007-31.12.2008. Emphysema around the lesion, length of the lung paranchyma traversed during biopsy, biopsy from cavity wall, travesing fissure, atelectasis and pleural tag were grouped into lesion related factors, type of biopsy, needle size, number of passages, procedure related factors. All variables were analysed by ki2 test.

Results: Among these patients 242 of them had CT guided FNAB and 210 patients had CT guided tru-cut biopsy. Complications were pneumothorax in 73 cases (16%) and in 46 cases (10%). A chest tube was ed only in 16 (3.5%) of them. The variable that was significantly associated with an increased risk of pneumothorax was length of the lung parenchyma and number of passages traversed statistically. The only variable that was significantly associated with an increased risk of pulmoner hemorrhage was type of biopsy needle.

Conclusion: Our results confirm that CT guided transthoracic needle biopsy are effective diagnostic methods with minimal complication rate.

Key words: Transthoracic Biopsy,Computed Tomography, Complication
