Superior mesenteric artery and aorto-iliac blood flow after surgical reconstruction in the aortic bifurcation.
In order to evaluate the possibility of a redistribution of blood from the superior mesenteric artery to the iliac-femoral region, as a cause of intestinal gangrene after surgical reconstruction in the aortic bifurcation, 149 patients operated upon during the last 10 years were reviewed. Aorto-iliac blood flow was studied in all the patients. Blood flow measurements on the superior mesenteric artery before and after release of the aortic clamp and after intra-arterial injection of a vasodilator were made in seven patients. No intestinal complications were found in the present material. The superior mesenteric artery blood flow showed little or no variations and a redistribution of blood from the mesenteric artery to the iliac-femoral region can hardly explain intestinal necrosis.
