The purpose of our study was to evaluate the usefulness of computed tomography (CT) fluoroscopy-guided transthoracic needle biopsy. Between March 1996 and March 1997,36 patients underwent CT fluoroscopy-guided transthoracic needle biopsy using a 18-gauge automatic biopsy gun. Examinations involved 30 pulmonary lesions (15 lung carcinomas, 3 pulmonary metastases, 12 benign lesions), 3 mediastinal lesions, and 3 pleural lesions. Sufficient materials for diagnosis were obtained from 34 of 36 lesions (94%). The sensitivity, specificity, and accuracy of CT fluoroscopy-guided transthoracic needle biopsy were 86.4%, 100%, and 91.7%, respectively. There were no cell-type misidentifications in cases in which resection was performed for carcinoma. Complications occurred in 19 of 36 cases (53%). The most common complication was pneumothorax, which occurred in 17 of 36 cases (47%). Chest tube insertion was required in 3 of 17 cases of pneumothorax. Intrapulmonary hemorrhage and hemoptysis occurred in 3 (8%) and 1 (3%) cases, respectively. No fatalities occurred after biopsy. In conclusion, CT fluoroscopy-guided transthoracic needle biopsy is useful.
