Superior mesenterorenal bypass for renal revascularization with infrarenal aortic occlusion

The technique of renal revascularization using a saphenous vein bypass graft from the superior mesenteric artery is described. This operation has been performed for the correction of renal artery stenosis in 4 patients with atherosclerotic aortic occlusion. When the requisite conditions are present, mesenterorenal bypass offers a safe and effective method of renal revascularization, and is preferable to aortic replacement in selected patients.
