Purpose: Which graft material is appropriate for the above-knee femoropopliteal (AK fem-pop) bypass has been a controversy. We were to evaluate the usefulness of PTFE graft in AK fem-pop bypass by comparing the results of autogenous vein graft in below-knee femoropopliteal bypass.
Methods: This was a retrospective study of data for Fem-Pop bypass from August 1999 to August 2008. The median follow-up was 59.9±27.3 months. The demographic data, patency rate, secondary procedures, and amputation rate were compared, and statistical comparison was performed by Kaplan-Meier method, Log-rank test, and Chi-square test.
Results: Seventy-three bypasses were performed in 63 patients: PTFE graft in 48 cases (Group A), autogenous vein in 25 cases (Group B). Sixty-one patients (96.81%) were men. The mean age was 67.3±8.0 years. The indication for surgery was intermittent claudication in 27 cases (37.0%), critical limb in 46 cases (63.0%). The 6-yr primary patency rates were 28.1%; 60.3%, the 6-yr secondary patency rates were 37.2±8.4%, 67.0±14.7% in Group A and Group B, respectively (P＜0.05). The number of secondary procedures was 31 and 3, respectively (P＜0.05). Major amputation at later periods was not needed in Group B, but there were 9 cases in group A (P＜0.05).
Conclusion: PTFE graft for above-knee femoropopliteal bypass shows poor long-term patency with a large number of secondary procedures and a higher amputation rate than vein graft in BK Fem-Pop bypass. PTFE graft should be limited to patients with high operative risk, or poor venous graft.
