Perigraft Seroma Presenting as Discharging Sinus and Spontaneous Exteriorization of Vascular Graft - A Rare Entity Following Vascular Repair with PTFE Graft.

Perigraft seroma presenting as discharging sinus and spontaneous exteriorization of vascular graft are rare complication of vascular injury repair with polytetrafluoroethylene (PTFE) grafts. We hereby report a case of young boy who presented with discharging sinuses and vascular graft coming out from one of the sinuses following vascular repair of femoral artery with PTFE graft after a follow-up of six months but the limb was salvaged. On evaluation PTFE graft was found to be thrombosed and collaterals were formed for distal perfusion. Because of persistent discharging sinuses, PTFE graft was removed and femoral artery was ligated proximal and distal to the graft. This case highlights an unusual complication of PTFE grafts that is commonly used in vascular surgery and also highlights the fact that these graft buy time for gradual collaterals formation for distal perfusion and hence when thrombosed and complicated can be safely removed.
