Abstract

OBJECTIVE: Distinct aspects can influence the complication rates of computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions. The purpose of the current study is to determine the influence of radiological techniques and clinical characteristics in predicting complications from this procedure. SUBJECTS AND METHODS: A retrospective study was developed involving 340 patients who were submitted to a consecutive series of 362 computed tomography-guided fine needle aspiration biopsies of lung lesions between July 1996 and June 2004, using 22-gauge needles (CHIBA). Variables such as the radiological characteristics of the lesions, secondary pulmonary radiological findings, co-morbidities, and aspects concerning the procedure were studied. RESULTS: The diameters of the lung lesions varied from 9 to 140 mm, with a mean of 51.5 ± 24.3 mm and median of 40mm. The depth of the lesions varied from 10 mm to 130 mm, with a mean of 44 ± 20.9mm, and median median of 52 mm. Complications occurred in 52 (14.4%) cases, pneumothorax being the most frequent, with 40 (11.1%) cases, followed by hemoptisis with 7 (1.9%) cases, and hematoma with 4 (1.1%) cases. Lesions that did not contact the pleura, with normal pulmonary tissue interposition between lesion and pleura, had higher complication rates, with 22 (22%) cases, than lesions that contact the pleura, with 6 (9%) cases, with a statistically significant difference (p = 0.03). CONCLUSIONS: CT-guided percutaneous fine needle aspiration biopsy of lung lesions had a lower rate of complications in our study and presented more rates of complications on lesions that lack pleural contact.
