| Abstract: | Improved instrumentation for venous valve extirpation has allowed rapid development of the in situ technique for femoral-tibial arterial reconstruction. Extension of this valvulotomy technique permits the expeditious construction of branched, nonreversed saphenous vein grafts for multiple vessel revascularization, and allows use of veins otherwise unsuitable in length for certain arterial bypass procedures. The nonreversed vein graft also appears to offer advantages over the reversed graft with regard to the size of the proximal and distal anastomoses when used as an aortorenal or iliorenal graft as well as in other anatomic locations. Over the past 30 months these techniques were used to implant 10 vein grafts at diverse sites in nine patients with initial success in all instances and one late graft failure. |
