Five late complications of dacron and autogenous vein graft anastomoses used in renal and lower extremity reconstruction were studied. Three patients had recurrent stenoses and 2 patients had anastomotic aneurysms. Surgical treatment was required in all patients. One patient developed aorto-renal-duo denal fistula and died in the immediate postoperative period owing to multiple organ failure. In the remaining 4 patients, secondary procedures were success ful. In patients in whom direct dacron and vein anastomoses have been con structed, careful late follow-up is essential to detect and manage these complications.
