[Venous fistulization of an iliac aneurysm (author's transl)].

The first reported case of a left iliac arteriovenous fistula from rupture of an aseptic atheromatous aneurysm is described. The fistula occurred proximally to a primary iliac vein thrombosis which explains the clinical picture observed of very severe "blue" phlebitis and the absence of any cardiac complications. The fistula was treated by the endo-aneurysmal approach and arterial continuity re-established with a prosthesis. The postoperative result was excellent.
