Extra-anatomical bypass of iliac vein obstruction: use of a synthetic (expanded polytetrafluoroethylene [Goretex]) graft

A. W. Clowes

A long synthetic graft polytetrafluoroethylene was used to provide an extra-anatomic bypass of an iliac vein obstruction secondary to recurrent thrombophlebitis. The graft has remained patent during the 12-month period of observation. A distal, previously placed arteriovenous fistula in this circumstance was important.
