title: Elective treatment of middle colic artery aneurysm.
abstract: Middle colic artery aneurysms are rare and most have been reported with rupture or symptom. We report the successful elective treatment of a middle colic artery aneurysm without symptom, which is very rare. It failed to perform transcatheter arterial embolization for anatomical reasons, and, thus, the patient, a 77-year-old man, underwent surgical resection in spite of a history of laparotomy. Although a common cause of middle colic artery aneurysms is segmental arterial mediolysis, the present pathological findings indicated that fragmented or degenerated elastic fibers may also play an important role like aortic aneurysms.
