Stent Grafting for Giant Bronchial Artery Aneurysm Disguised as an Aneurysm With Multiple Feeding Arteries

We report a case of a giant mediastinal bronchial artery aneurysm disguised as an aneurysm with multiple feeding arteries. A 74-year-old man with a history of bronchiectasis was admitted to our hospital for treatment of a bronchial artery aneurysm. Because the segment of feeding vessels between the thoracic aorta and the aneurysm was short, it was not possible to occlude the feeding artery simply by transarterial embolization. A combined procedure of stent-graft occlusion of the inflow artery and coil embolization of the outflow artery was successfully performed.
