title: [Autologous venous graft disease. Incidence, physiopathologic aspects and therapeutic means of graft salvage].
abstract: From 1980 to 1985, 134 patients with severe ischemia of lower limbs benefited from surgical recovery by inversed autologous venous graft in subarticular femoropopliteal and distal femoral position. During the 5 year follow-up period, 14 grafts (9%) developed hemodynamic degradation requiring angiographic surveillance followed by surgical repair or percutaneous dilatation. A retrospective study of evolution of venous grafts implanted in the contralateral supra-articular femoropopliteal and femoro (ilio) femoral position demonstrated a lower incidence of hemodynamic degradation (5.3%). Localizations (proximal and distal anastomotic stenosis, valvular stenosis, stenotic degradation of the donor or receiving arterial segment) and physiopathologic mechanisms (progressive atheromatosis, anastomotic or valvular fibrosis, premature atheromatosis of graft) are systematically reviewed together with results of pathology. Etiopathogenic factors invoked for this affection are discussed as a function of findings, together with choice of therapy used, including surgical repair, fibrinolysis and percutaneous dilatation.
