A case of bilateral pulmonary arteriovenous fistula treated by both embolization and surgical combined therapy

Abstract

A 56-year-woman was admitted to the hospital with an abnormal shadow in the left lower lung field on chest X-ray film. The findings on chest CT examination suggested a pulmonary arteriovenous fistula. Left pulmonary arteriogram showed a large fistula (60 mm) with feeding vessels of 8 mm in diameter in the left lower lobe. It seemed to be impossible to perform embolization because of the size of fistula and its feeding vessels. Right pulmonary arteriogram at the same time revealed a small fistula of 10 mm in diameter in the right lower lobe, which was treated by embolization. The fistula of the left lung was resected on thoracotomy.
