An alternative source of visceral arterial inflow is sometimes necessary for renal revascularization when aortorenal endarterectomy or bypass is inappropriate due to severely diseased aorta. We report the case of a 46-year-old male with recurrent intractable renovascular hypertension in renal failure secondary to occlusion of the celiac axis due to progression of aortoarteritis following splenorenal arterial bypass performed 5 years before. Aortogram visualized intestinal arterial arcade supporting patent bypass with critically stenosed superior mesenteric artery. Successful angioplasty with stenting of superior mesenteric artery restored adequate renal flow through the bypass leading to recovery and easy control of hypertension.
