Colonic Ischemia After Endovascular Exclusion of an Aortoiliac Aneurysm Using an Iliac Branch Device

Abstract

Purpose: To present the first case of colonic ischemia (CI) after endovascular exclusion of an aortoiliac aneurysm using an iliac branch device (IBD). Case report: A 69-year-old male patient with an abdominal aortic and right common iliac artery aneurysm underwent endovascular repair with an IBD. Completion angiography demonstrated good patency in 2 of the 3 main branches of the right internal iliac artery (IIA) whereas the left IIA patency was preserved. Preoperatively, the inferior mesenteric artery (IMA) was patent. Postoperatively, the patient presented moderate CI. He was treated conservatively and discharged 15 days later with recession of the symptoms. Conclusion: Although preservation of bilateral iliac artery patency is considered to diminish the incidence of pelvic ischemia, in case of an exclusion of a patent IMA, collaterals may not be adequate to ensure blood supply to the left colon.
