[Treatment of 11 cases of pulmonary arteriovenous fistula].

We have experienced a total of 11 patients operated for pulmonary arteriovernous fistula (PAVF) from 1976 to 1993 consisting of three males and eight females with the average age of 35 years. To reserve the pulmonary function, limited resections were applied for all cases (partial resection in 8, fistula excision in 2, and segmentectomy in one case). The most recent case, a 36-year-old female who had two abnormal shadows on her routine chest X-ray, was diagnosed as PAVF by pulmonary arteriogram. She was treated by fistula excision in the right S8 lesion and embolization in the left S1 + 2 lesion. Because of its unsatisfactory natural course, PAVF should be treated aggressively by surgery and/or by embolization according to the size, shape and localization.
