    Abstract:
    From 1972 to 1983, 78 patients underwent surgical treatment for renovascular hypertension caused by a lesion limited to the trunk of the renal artery. Forty-five of these patients underwent aortorenal bypass (24 saphenous grafts and 21 arterial hypogastric grafts); 36 patients (80%) had either a relief of the hypertension or were improved. Graft closure occurred in five cases. Thirty-three patients were treated by autotransplantation of the kidney. After resection of the lesion, the renal artery was anastomosed end-to-end to the hypogastric artery or end-to-side to the common iliac artery and the renal vein and side-to-side to the iliac vein or the origin of the vena cava. In this group all patients but one (97%) had relief of the hypertension or were improved. No thrombosis was observed. Late angiography was performed 5 years after surgery in 19 patients (nine autotransplantations and 10 bypass operations): patients who underwent autotransplantation had no alteration of the renal vessels whereas four patients who underwent bypass operations had dilatation of the saphenous vein bypass. Renal autotransplantation was superior to the bypass technique in the surgical treatment of renovascular hypertension caused by lesions of the trunk of the renal artery and may represent a better alternative in the surgical treatment of this condition.
