Abstract
Mediastinal aneurysms are rare but potentially life-threatening. Among these, bronchial artery aneurysms are most frequently reported, whereas up to now aneurysms of the proper esophageal artery had never been reported. A 69-year-old woman was referred to our hospital for treatment of a massive mediastinal hematoma. Enhanced computed tomography and selective proper esophageal arteriography revealed a 5-mm aneurysm in the proper esophageal artery that arises from the thoracic aorta at the Th8 level and has an anastomotic branch with the bronchial artery peripherally. Transcatheter arterial embolization was successfully performed using a mixture of N-butyl cyanoacrylate and lipiodol (1:3 ratio, 0.3 ml). Post-embolization angiography showed no filling into the aneurysm. The patient recovered with no complications and was discharged on the 25th post-procedure day.
