Interposition graft with polytetrafluoroethylene for mesenteric and portal vein reconstruction after pancreaticoduodenectomy

Abstract

Background; Portal vein-superior mesenteric vein resection is frequently required after surgical resection of tumours of the pancreas head. The ideal graft for portal vein reconstruction (PVR) remains undefined. Methods: Between May 2000 and July 2007, 28 patients had portal vein-superior mesenteric vein resection and PVR during pancreaticoduodenectomy. Their clinical reports were reviewed retrospectively with specific attention to the methods of PVR and outcomes. Results; Ten patients had PVR with primary anastomosis, seven had PVR with autologous vein, one had a polytetrafluoroethylene (PTFE) patch, one did not have PVR and nine had PVR with a PTFE interposition graft. There was no infection after PTFE grafting. Six patients had PVR thrombosis after surgery: four after primary anastomosis, one after interposition PTFE and one after vein repair. Conclusion: PTFE appeared to be an effective and safe option as an interposition graft for portomesenteric venous reconstruction after pancreaticoduodenectomy.
