A Case of Bronchial Arterial Aneurysm

Abstract

A 44 year-old man was admitted to our hospital with a complaint of more than 200ml hemoptysis. Chest X-ray film on admission showed an infiltrative shadow in the right lower lung field. Bronchofiberscopic examination revealed a 4cm elevated mass at the membranous portion of the right basal bronchus. During the obervation approximately 1500ml bleeding suddenly developed and bronchial arteriography, which was performed immediately revealed a circular aneurysm about 5mm in diameter at the right basal bronchus. Therefore, bronchial arterial embolization (BAE) was successfully performed using gel sponge cubes and bronchial artery was knoted in fear of resumption. The patient has experienced no episode of hemoptysis since.
