[Role of renal autotransplantation in the treatment of renal arterial lesions].

112 patients with hypertensive lesions of the renal artery were studied. 33 patients with stenosis of the trunk of the renal artery were operated with autotransplantation. 10 patients had lesions of the main branches of the renal artery and in these cases autotransplantation with the anastomosis of the two main renal artery branches to the two main branches of the hypogastric artery was performed. 24 patients with complex lesions of renal artery branches were treated with autotransplantation associated with extracorporeal repair of the renal artery. 45 patients, with lesions of the trunk of the renal artery were operated by aortorenal bypass. For lesions of the main renal artery, results were better in the group of patients treated by simple autotransplantation (82% of patients cured versus 46% with bypass operation). For lesions involving multiple branches of the renal artery extracorporeal replacement of the renal artery followed by autotransplantation often represents to the sole technique to prevent nephrectomy. Hypertension was cured or improved in more than 80% of cases. We believe autotransplantation to be the best operation for lesions of the renal artery in most cases.
