Acute perigraft seroma simulating anastomotic bleeding of a PTFE graft applied as an arteriovenous shunt for hemodialysis.

Perigraft seroma is an uncommonly reported complication of polytetrafluoroethylene grafts applied as an arteriovenous shunt for hemodialysis. It usually presents as a soft tissue swelling around the arterial end of the graft and occurs within 30 days after implantation. An unusual presentation of perigraft seroma occurring immediately after implantation is reported herein.
