[Interest of fistulography in the treatment of infection of arterial prostheses (author's transl)].

In groin distal anastomosis suppuration of an aorto or ilio-femoral prosthesis, preoperative opacification of the fistulous tract was used to assess the extent of infection along the prosthesis. In two patients, one with an ilio-femoral by-pass whose entire length was infected, and the other having an aorto-bifemoral by-pass with only one infected distal anastomosis, fistulography enabled us to plan the operative procedure consisting of venous by-pass and resection of the infected segment.
