Vein Interposition Model: A Suitable Model to Study Bypass Graft Patency

Long-term patency of venous repairs demonstrated by venography
Abstract:
Indications for venous reconstruction after traumatic injury are controversial, partly because of uncertainty of continued patency. We found no reports in the literature of truly long-term results after venous reconstruction. For clarification of this issue, we reviewed femoral venous injuries in a civilian metropolital population over a 20-year period. There were 31 patients with penetrating femoral venous injuries. Twenty-four patients underwent reconstruction. A search for these patients years after reconstruction located only five patients with six reconstructions. Followup venography at 6 to 20 years demonstrated venous patency and functional valves with asymptomatic patients and no clinical evidence of venous insufficiency in all cases excluding a single 1962 repair with a Teflon graft. This study then supports reconstruction rather than ligation after venous trauma. Although small, this series appears to be the only known report of truly long-term results following venous reconstruction.
