[Renal revascularization from the digestive arteries in the treatment of renovascular hypertension in high risk patients].

Five extra-anatomic hepatospleno- and gastroduodenorenal revascularizations were performed in 5 high-risk cardiac patients. The procedure followed failure of endoluminal angioplasy for osteal stenosis of the renal artery in 4 cases. All patients had a diffuse lesion of the aorta contraindicating direct aortorenal bypass. The indication for surgery was renovascular hypertension poorly-controlled with medical therapy in all 5 patients; 4 patients also had renal failure. There was no mortality in the perioperative period. Blood pressure returned to normal in 50% of the cases, and improved in the other 50%. There was a clear improvement in renal function in all patients.
