A case of ischemic colitis due to the embolization therapy of inferior mesenteric artery aneurysm

Abstract

We report the case of an 84-year-old man with an inferior mesenteric artery aneurysm three years after rectal cancer surgery. An enhanced computed tomography showed the aneurysm in the inferior mesenteric artery area. We performed a transcatheter arterial embolization through the inferior mesenteric artery. Although an ischemic colitis occurred around the embolization area about two weeks later, the patient recovered without any stenosis. An inferior mesenteric artery aneurysm is a rare disease among visceral aneurysms, and here we report a successful transcatheter arterial embolization therapy.
