[Necrosis of the colon and rectum as a complication of aortic reconstruction surgery].

The author reports on two patients operated on for necrosis of left colon after aorta-bifemoral by-pass reconstruction and presents another by whom ischemic rectum necrosis occurred as complication of aorta aneurysm.
