Long-term Patency of Femoro-Popliteal Bypass with Artificial Grafts / 日本心臓血管外科学会雑誌

Femoropopliteal bypass (FP bypass) with woven Dacron grafts was performed in 159 legs of 122 patients from November 1980 to June 1993. The operative mortality rate was 0.8%. Actuarial analysis at 10 years for overall patency of FP bypass was 75.1% (mean follow-up 45.1 months). Both univariate and multivariate analysis revealed three risk factors affecting long-term patency; poor run off, difficulty in anticoagulation therapy and high serum cholesterol. The 5-year patency rate with these factors were 55.8% (<i>p</i><0.01), 61.7% (<i>p</i><0.01) and 63.9% (<i>p</i><0.05), relatively. Therefore we recommend early surgical treatment, and strict control of anticoagulation and adequate treatment of hyperlipidemia are of great importance.
