Retro-sartorius bypass in the treatment of graft infection after peripheral vascular surgery.

Abstract

Extra-anatomic bypass is preferred for revascularization after removal of infected vascular grafts. The obturator canal technique has been used to bypass an infected field in the groin, although this method has not always been definitive because of several drawbacks. We present a unique method of extra-anatomic revascularization for use in such a situation. An autogenous graft is placed just below the sartorius muscle in the thigh and penetrates the iliacus muscle near the lateral end of the inguinal ligament. Limb loss and recurrent infection are prevented postoperatively. This retro-sartorius bypass technique may be a useful alternative to obturator bypass grafting in selected patients.
