The decision to revascularize an occluded main renal artery is often extremely difficult, especially when aortic and renal occlusive disease co-exist. The main objectives of surgery are preservation of renal parenchyma and possible amelioration of renovascular hypertension, provided the patient's condition permits. In a 52-year-old man with renovascular hypertension and intermittent claudication transfemoral aortography revealed severe atheromatosis of the aorta and iliac arteries. There was total occlusion of the left main renal artery, but the right renal artery was patent. Aorto-femoral bypass was performed using a bifurcated graft. The left kidney was revascularized using an 8-mm straight graft anastomosed end-to-end with the renal artery and the other end was inserted into the distal part of the bifurcated graft, constituting a triple bypass. The postoperative course was uneventful, blood pressure decreased and renal scan showed good left renal function. 6 months later aorto-bifemoral and renal bypass grafts were fully patent.
