Autologous Arterial Reconstruction in the Treatment of Renal Artery Stenosis

Abstract

Renal revascularization was performed using the internal iliac artery in 25 patients. The causes for arterial damage were fibrodysplasia in 19 cases, athero sclerosis in 5 and aneurysm in one. Simple autotransplantation was performed in 10 cases, and ex-situ repair with subsequent autotransplantation in 15. Mean postoperative followup was 5.2 years; renal volume, evaluated with planimetry in IVP, was improved in 65% of the cases. Sixty-eight percent of the patients were cured from hypertension, 28% improved and 8% remained unchanged.
