The authors analyze a series of 383 kidney transplantation pointing out the role of recipient's vessels atherosclerosis in the determination of vascular complication of the kidney graft. Three groups were considered. The first included 55 patients which required TEA for severe atherosclerotic lesion of the anastomosed vessels. The second group included 305 patients who didn't required TEA; the third group was of 20 patients who received a graft with multiple arteries which required more than one anastomosis. A significative higher rate of arterial complications was evident in the first group (p less than 0.001). Within this group the end to end arterial anastomosis was more frequently associated to thrombosis or stenosis than the end to side one (p less than 0.05). Kidney with multiple vessels also presented with an higher rate of complications (p less than 0.05).
