Long-term results after femoral thrombendarterectomy combined with simultaneous endovascular intervention in intermittent claudication and critical ischemia.

OBJECTIVE

This population-based retrospective cohort study investigates long-term results of femoral thrombendarterectomy combined with simultaneous endovascular intervention of the iliac or femoropopliteal vessels, or both, with focus on freedom from recurrent intervention, limb salvage and survival.

METHODS

All patients undergoing femoral thrombendarterectomy and simultaneous endovascular intervention between 1999 and 2013 were included. Stratification was according to clinical symptoms, intermittent claudication or critical ischemia, with subgroups for rest pain and ulcer/gangrene, and for type of endovascular intervention, iliac, femoropopliteal or both. We assessed technical success, 30-day complications, freedom from recurrent intervention, survival and amputation free survival in all patients. Limb salvage was assessed in patients with critical ischemia.

RESULTS

We identified 151 operations in 143 patients with a total of 164 limbs treated. A total of 13 patients had bilateral and 8 patients had subsequent contralateral operations. Indication was intermittent claudication in 87 (57.6%) and critical ischemia in 64 (42.4%) operations. Thirty-day mortality, only observed in critical ischemia, was 5/64 (7.8%). Freedom from recurrent intervention after 5 years was 91% in intermittent claudication and 70% in critical ischemia. In total, 84% of the patients with claudication were improved at the end of the study. Limb salvage at 5 years was 75% in critical ischemia, 93% in rest pain and 64% in patients with ulcer or gangrene.

CONCLUSION

Femoral thrombendarterectomy combined with endovascular iliac or femoropopliteal intervention has good and durable results in intermittent claudication and critical ischemia, especially in patients with rest pain. In most cases, a single operation is sufficient.
