Abstract
There is increasing emphasis on carrying femoro-popliteal bypass grafts below the knee and most vascular surgeons agree that reversed saphenous vein makes the best graft. However, some other considerations have become important and deserve consideration. P.T.F.E. grafts in this location have almost as good a long term patency rate as autologous vein grafts. Some very experienced vascular surgeons have indicated their preference for this type of graft, citing some of these pertinent reasons: Peripheral vascular disease usually is associated with lesions in other vessels. Since coronary artery bypass has become so commonly used to stave off myocardial infarction some thought should be given to preservation of suitable saphenous veins for this purpose. Harvesting the saphenous vein adds additional surgical trauma, time, exposure to sepsis, lymphatic interruption and extra incisions. Once we opt for preferential P.T.F.E. grafts, then we start to search for a simpler technique.
