STUDY AIM: The aim of this retrospective study was to report immediate and long term results of endarteriectomies of the common femoral artery (CFA) and/or femoral tripod and to analyse predictive factors of failure. PATIENTS AND METHODS: Between 1982 and 1995, 110 endarteriectomies were performed in 101 patients, 52% of them in limb salvage situation. The arteriogram showed a thrombosis or stenosis of the common femoral artery in 100% of cases. There was a stenosis of the deep femoral artery (DFA) in 79% of cases. The superficial femoral artery (SFA) was thrombosed in 40% of cases. One artery only of the lower leg was permeable in 43.3% of cases. Run off was judged bad in 38% of patients. RESULTS: The endarteriectomy could be realised in 93 patients (84.5%). It concerned the only common femoral artery in 20% of cases (patch angioplasty in 55% of cases), common and deep femoral arteries in 50.5% of cases (82% of patch), CFA, DFA and SFA at its origin in 29.1% of cases (93% of patch). Perioperative mortality rate was 1%. Local morbidity rate was 21.6% with 18% of minor complications and 3.6% of complications requiring a second operation. There were 2% of vascular complications (1 thrombosis and 1 false-aneurysm). Mean follow-up was 43 months in 90 patients. There were restenosis or thrombosis (5.5%), false-aneurysms (2.2%) and amputations (6.6%). Femoro-popliteal (10%) and iliac complementary bypasses (6.6%) were necessary. Permeability was 94.9% at 3 years and 88.8% at 5 years. Clinical results were considered good in 80.7% of the cases at 3 years and in 71.7% at 5 years. With univariate analysis, the predictive factors for failure were: limb salvage (P < 0.01), altered popliteal run off (P < 0.03) and extended distortion of the deep femoral artery (P < 0.05). CONCLUSION: Isolated endarteriectomy of the femoral tripod is a low risk and effective technique. A femoropopliteal revascularisation should be associated in case of a major alteration of the deep femoral artery.
