Abstract
Thirty patients were operated for arterial reconstruction with synthetic grafts. They presented one of the following complications: 1) prosthesis exposed by a cutaneous fistula; 2) prosthesis in communication with a hollow viscus; 3) prosthesis involved by pus; 4) positive culture of a fragment of the prosthesis or of the surrounding secretion. The clinical manifestations were cutaneous fistula in 21 patients (70%), external bleeding in 14 (47%), exposition of the prosthesis in five (17%), anastomotic aneurysm in five (17%), and enteric fistula in four (13%). The infection became evident during the first postoperative year in half of the patients. The most important agents of infection were staphyilococci and Gram negative bacteria.
