title: A Case of Intestinal Necrosis after Bilateral Internal Iliac Artery-Preserving Endovascular Repair for Abdominal Aortic Aneurysm.
abstract: A 79-year-old man underwent endovascular repair for abdominal aortic aneurysm (AAA), and both internal iliac arteries (IIAs) were preserved. Postoperatively, loss of appetite developed. On the fifth day, computerized tomography (CT) showed inferior mesenteric artery thrombus formation, necrosis of the descending colon and rectum, and generalized peritonitis. The endovascular devices had not migrated. A colonic resection was performed. Histological analysis confirmed intestinal necrosis associated with mesenteric thrombus. The colon can become necrotic even if both IIAs are patent. Ischemic changes in the colon should be detected if it occurs and subsequent laparotomy should be done if it is necessary.
