In eight patients in whom the traditional inflow arterial sources of the aortoiliac and axilliary arteries were unavailable for limb or visceral revascularization, the celiac and superior mesenteric arteries were successfully used. These proved to have satisfactory flow characteristics and to be easy to expose and use. Angiographic data suggest that the superior mesenteric artery is less frequently diseased at its origin than the celiac artery. No steal or redistribution problems were encountered.
