Popliteal Endarterectomy for Localized Popliteal Artery Disease

Abstract

The incidence of localized popliteal disease is rare. Currently, patients presenting with symptomatic popliteal disease are offered femoropopliteal or tibial bypass if the disease is not amenable to radiologic intervention. We feel that popliteal endarterectomy by means of a posterior approach with patch angioplasty as a primary procedure is a viable surgical option. Our aim was to assess the durability of popliteal endarterectomy in patients with localized popliteal disease, in which radiologic intervention is not feasible. This is a retrospective review of all patients who underwent popliteal endarterectomy for localized popliteal disease in our institution over the past 3 years. All patients underwent a preoperative assessment with computed tomography angiography. Angioplasty was attempted in all patients before surgical intervention. Patency was assessed radiologically 6 weeks after operation. Patients had follow-up appointments at intervals of 6 weeks, 3 months, 6 months, and a year after surgery. A total of 7 patients (5 men and 2 women) underwent popliteal endarterectomy. The mean age was 64.3 years, with a mean follow-up period of 9.9 months (range, 2-26 months). Four patients were treated for activity-limiting claudication (<100 yards), whereas 3 patients were treated for ischemic rest pain. The procedural success rate was 100% without mortalities or in-hospital morbidities. Symptomatic resolution was achieved in 6 patients. One patient occluded 1 month after endarterectomy because of a critical stenosis at the tibial bifurcation. Popliteal endarterectomy through posterior approach is advantageous in managing popliteal artery pathology restricted to the popliteal fossa. It is safe with good short-term results.
