Prevention of ischemic disorders in the left colon after resection of intrarenal aortic aneurysm

Infrarenal aortic aneurysm was resected in 125 patients, 52 of them having undergone the resection of the common iliac artery. Inferior mesenteric artery was implanted into a prosthesis in 17 cases (13,6%), while shunting of one internal iliac artery was performed on 2 patients. Anterograde or retrograde blood flow remained in one or two internal iliac arteries in 90 patients (72%). Average arterial blood pressure in the inferior mesenteric artery and in the internal iliac arteries was over 40 mm Hg in 14 patients (11,2%). 12 patients (9,6%) developed ischemic colitis including 5 cases of intramural ischemic colitis which terminated lethally. Prevention of ischemic colitis should be based on preservation of the blood flow in the internal iliac arteries and/ or inferior mesenteric artery with the help of their implantation.
