Ask Dr. Z

Our vascular surgeon documented fem to posterior tibial bypass done with synthetic graft and saphenous vein graft. This was due to saphenous vein not being sufficient length to accomplish the bypass, so he elected to perform a composite Gore-Tex and saphenous vein graft. End-to-side anastomosis done with the synthetic graft to the femoral, posterior tibial anastamosis was accomplished by means of an end-to-side anastomosis with the saphenous vein and end-to-end anastomosis was accomplished from the saphenous vein to the distal Gore-Tex graft. Would I use an unlisted for this procedure?
