[Infection of artificial vascular prostheses. Case reports].

Four patients with prosthetic graft infection are presented. In 3 patients infection occurred in a Dacron aortobifemoral graft. In all 4 patients the infection originated at the femoral anastomoses. In 2 patients the entire aortofemoral graft was removed; one patient died of septicaemia and the other required an above-knee amputation. In 1 patient partial removal of the graft limb proved successful after a femorofemoral bypass using an autogenous venous graft. Above-knee amputation was performed in a further patient after removal of an infected axillofemoral graft. Staphylococcus was consistently isolated from the infected grafts in all the patients.
