Arterial grafts are apparently now preferred by many to replace segments of peripheral arteries. However, vein grafts, either autogenous or homologous, are still the most available, and it is important to evaluate the long-term results. Various objections raised to the use of vein grafts are, namely, the dilatation under arterial pressure, the tendency of vein grafts to close, and technical difficulties in their placement. Actually, one must differentiate several aspects of the problem. First, vein grafts used to replace segments of arteries which have been injured and in which the vein graft is sutured to the normal artery proximally and distally usually stay open and function in almost every case. Here the flow of blood is good, and there is no obstruction proximally or distally. It is difficult, however, to find longterm follow-up of these cases. Secondly, vein grafts placed in a large artery, such as the aorta, without good
