Traumatic fracture of polytetrafluoroethylene axillofemoral bypass graft.

We report traumatic disruption of a ringed polytetrafluorethylene (PTFE) axillofemoral bypass (AFB) graft due to a fall. We also review the literature of previously reported blunt traumatic PTFE graft disruptions. A 75-year-old man with previous bilateral AFB grafting presented with a painful left chest wall mass after a fall from standing height. Chest computed tomography (CT) revealed a large chest wall hematoma. The patient underwent evacuation of the hematoma, resection of the fractured graft, and placement of an interposition PTFE graft. Two prior case reports have documented the midportion PTFE graft disruption from blunt trauma. Our case report demonstrates the potential for disruption of the midportion of ringed PTFE AFB grafts with direct blunt trauma. The diagnosis was confirmed by CT scan and the graft was successfully repaired with an interposition graft.
