title: A case of inferior mesenteric artery aneurysm with an occlusive disease in superior mesenteric artery and the celiac artery.
abstract: A 72 year-old man was referred to our hospital for treatment of a gradually expanding inferior mesenteric artery (IMA) aneurysm associated with an occluded superior mesenteric artery (SMA) and a severely stenosed celiac artery (CA). Using 64-slice computer tomography (CT), we were able to accurately define a precise collateral visceral circulation from the IMA to the SMA and the CA, greatly clarifying preoperative strategy. The aneurysm was subsequently removed, with revascularization of the SMA and the CA accomplished through grafts from the abdominal aorta using 6 mm polytetrafluoroethylene (PTFE) grafts.
