title: Nonanastomotic pseudoaneurysm of expanded polytetrafluoroethylene axillofemoral bypass graft.
abstract: A case of nonanastomotic pseudoaneurysm of a unilateral axillofemoral bypass graft is reported. The graft material used in this particular instance was an 8 mm, reinforced, thin-walled, fluorinated ethylene-propylene-ringed, expanded polytetrafluoroethylene (ePTFE). The pseudoaneurysm occurred 1 year after insertion of the graft and was not associated with any direct trauma. It manifested with a painful tender mass at the top of the body of the axillofemoral bypass graft at the level of the nipple line. There were no symptoms of localized or diffuse sepsis. Immediate surgical exploration confirmed the diagnosis of a pseudoaneurysm of the ePTFE graft. Successful repair of the disrupted segment was accomplished by use of an interposition, nonringed, reinforced, thin-walled, 8 mm ePTFE graft. To our knowledge this is the first case of a nonanastomotic pseudoaneurysm of a ringed, ePTFE, axillofemoral bypass graft not associated with direct trauma.
