Expanded polytetra fluoroethylene (PTFE) graft in hemodialysis

Currently, PTFE grafts are regarded to be the alternative method of choice for patients with failed conventional fistulae. Observation over a longer period is necessary to assess the long term patency rate. Our experience in the use of PTFE grafts in providing vascular access for selected patients is reviewed. Thirty grafts were implanted in twenty-six patients over a sixteen-month period. Complications noted were thrombosis (six patients) and infection (two). Twenty patients were successfully hemodialysed without complications. Two additional patients had access provided for long term parenteral therapy or transfusion.
