  • Title: Prosthetic above-knee femoropopliteal bypass.
    Author: Illig KA, Green RM.
    Journal: Semin Vasc Surg; 1999 Mar; 12(1):38-45. PubMed ID: 10100384.
    Abstract:
    One of the classic and as yet unresolved arguments in vascular surgery is whether using prosthetic for a first-time above-knee femoropopliteal bypass, to "save the vein" for a later, more distal bypass, is of net benefit. Most of the arguments supporting use of prosthetic for a first bypass in this situation are, in fact, not supported by the literature, whereas most of the arguments in favor of using vein first are. In addition, decision analysis shows that overall amputation-free survival and number of operative procedures required are clearly better if vein is used first under essentially all conditions--the overwhelmingly strongest determinant of outcome is patency of the first bypass, and the superior patency of initial bypass with vein mathematically outweighs the ability of the "preserved" vein to salvage failures after an initial bypass with prosthetic. Theoretical, empirical, and mathematical arguments all strongly favor preferential use of vein for a first bypass to the above-knee popliteal artery.
