• Microporous expanded polytetrafluoroethylene (PTFE) has recently been proposed as an arterial graft. Although excellent graft patency rates have been achieved both experimentally and clinically, aneurysm formation of the graft has occurred in a small number of cases. This report describes a further case of aneurysm formation in a PTFE graft five months after insertion. We discuss the possible causes of graft aneurysm formation and a newly developed reinforced form of PTFE graft.
