[Arteriopathies of the lower limbs and lesions of the renal arteries].

Thirty-two patients underwent simultaneous reconstruction of aortoiliac vessels and of renal artery(ies). Two groups of patients were defined: groupe I (N = 22), with lesions of the artery(ies) of their native kidney(s), had renal artery repair on one or both sides for a total of 29 repairs; groupe II (N = 10) had repair after previous renal homotransplantation. There was no postoperative mortality in the current series. Late deaths were due to myocardial infarcts in most cases. Blood pressure control was obtained in 76% of the patients but only 26% of complete cure of hypertension without medical treatment were observed, the remaining patients requiring the administration of antihypertensive drugs; 24% of the operated patients were unchanged as to their hypertensive state and required a heavy medical treatment. In patients with renal failure, improvement of renal function was observed only when the functional impairment was slight or moderate. In the particular case of aortoiliac surgery in renal transplant patients, no special measure was used to protect the kidney during the arterial clamping; the organ resumed its function immediately after its revascularization; chronic rejection led to hemodialysis in two patients after 1 and 2 years. Results obtained in this series show that surgical repair of aorta and renal artery(ies) may be undertaken with low operative risk. It appears to be a safe procedure and gives satisfactory results.
