RESUMO
BACKGROUND: The femoropopliteal vein (FPV) has been used successfully for vascular reconstructions at multiple sites. To date, there have been no studies documenting patency of the FPV graft in the femorofemoral position. Our goal was to assess long-term patency of the FPV graft used for femorofemoral bypass (FFBP). METHODS: Patients undergoing FFBP over a 10-year period were studied. Those in whom the FPV was used as a conduit were analyzed for runoff resistance score to assess how patients with poor runoff fared. Poor runoff was defined as a runoff resistance score of > or =7 (1 = normal runoff, 10 = total occlusion of all runoff vessels). RESULTS: Fifty-four patients underwent FPV FFBP as a sole procedure (n = 16, 30%) or as a portion of an aortofemoral reconstruction with a FFBP component (n = 38, 70%). Mean (+/- SD) follow-up was 47 +/- 33 months. The 1-, 3-, and 5-year primary patencies were 97%, 93%, and 76%. The 5-year assisted primary and secondary patency rates were 85% and 90%. Among 27 patients with poor runoff (runoff resistance score of > or =7), the cumulative 40 month patency rate was 90%. Among patients in whom FPV FFBP was performed as a primary procedure (no aortofemoral component), there were no graft failures. CONCLUSIONS: FFBP performed with FPV has excellent 1-, 3, and 5-year patency rates. FPV has sustained patency for FFBP in patients with poor runoff.
