Microvascular anastomosis of a rectus abdominis free flap into a prosthetic vascular bypass graft.

Distal bypass grafts are frequently employed to revascularize lower extremities and to replace major peripheral vessels following excision of large soft-tissue or bone tumors. Autogenous vein grafts are generally used for such bypasses, when available. Large wounds associated with peripheral vascular disease or excision of massive tumors frequently require concomitant free-tissue transfers. Anastomosis of a free-tissue transfer pedicle to a vein bypass graft has been reported. The first successful case of an anastomosis of a flap pedicle to a Gore-tex bypass graft is presented.
