Serous leak, a rare complication of polytetrafluoroethylene grafts: a case report

Perigraft seroma is a rare complication of polytetrafluoroethylene grafts especially in the lower limb. It is often difficult to treat and recurrence is common. We present a case of a young woman who sustained a persistent perigraft seroma following a polytetrafluoroethylene graft in the proximal thigh, which was implanted as an alternative to an arteriovenous fistula. The cause was not ascertained and this was eventually treated by complete removal of the graft. This case highlights an unusual complication of polytetrafluoroethylene grafts that are commonly used in vascular access surgery, which can be challenging to treat.
