Abstract
Background Long-term outcome after endarterectomy of the femoral bifurcation has not been widely investigated, and the aim of this study was to assess its late results from a community-wide perspective. Patients and Methods Between 1983 and 2006 111 isolated endarterectomies of the common femoral artery and/or the proximal part of the superficial femoral artery or profunda femoris were performed in 90 patients at the Oulu University Hospital, Oulu, Finland. A total of 77 limbs were treated surgically for claudication and 34 others for critical limb ischemia. Angiographic findings of 100 extremities were evaluated. Results The in-hospital mortality rate was 1.8%. The mean follow-up period was 5.9 years. At 5-, 10-, and 15-year follow-up the overall survival was 60.5%, 32.7%, and 17.6%, respectively (S.E < 0.05). A C-reactive protein value ≥ 10 mg/l was predictive of poor late survival (p = 0.008). Limb salvage rates after isolated femoral endarterectomy at 5-, 10-, and 15-year follow-up were 93.7%, 93.7%, and 85.2%, respectively (S.E. < 0.08). Critical limb ischemia (p = 0.006) and current smoking (p = 0.027) were independent predictors of major lower limb amputation. A total of 41 limbs were subjected to ipsilateral vascular procedures after femoral endarterectomy, only one of which was re-endarterectomy. Freedom from any ipsilateral revascularization procedure at 5-, 10-, and 15-year follow-up was calculated at 68.0%, 50.6%, and 42.5%, respectively (S.E. < 0.08). The overall linearized rate of reintervention on the ipsilateral limb was 0.16 ± 0.44/year. The linearized rate among patients who had any ipsilateral vascular reintervention was 0.43 ± 0.66/year. Conclusions Isolated femoral endarterectomy is a rather low-risk and durable procedure. However, a significant number of reinterventions distal or proximal to the endarterectomized site can be expected in one third of patients.Keywords
