Eversion Endarterectomy Of The Femoral Bifurcation: Technique, Results And Potential Advantages.

Background: Despite recent advances in endovascular techniques, surgical endarterectomy remains the "gold standard" for treatment of atherosclerotic lesions of the femoral bifurcation. Eversion endarterectomy (EE) of the femoral bifurcation is a well-known technique that en- sures an extensive plaque removal; furthermore, EE can be performed to avoid the use of prosthetic material. The aim of this study is to evaluate the efficacy and safety of the EE of the femoral bifurcation in a contemporary prospective series from a single-center experience. Materials and Methods: All patients undergoing EE at our institution between January 2014 and December 2016 were retrospectively reviewed. EE was performed as an isolated procedure or in a hybrid fashion. Clinical presentation was defined according to Rutherford?s classification. End points included major complications and patency rates. Results: Thirty-three EEs were performed on 31 patients during the study period. Thirteen procedures (39%) were performed in a hybrid fashion with concurrent endovascular inter- ventions. Technical success was achieved in 100%. Thirty-day mortality was null, whereas 5 overall complications (15%) were recorded; among those, 2 (6%) were major. In both cases, an early thrombosis of the femoral bifurcation occurred, successfully treated by a short Dacron replacement of the common femoral artery. During follow-up, no femoral pseudoaneurysm or groin infections were observed. Two restenosis occurred at 7 and 10 months after EE, respectively. Two-year primary patency and assisted primary patency rates were 87% and 100%, respectively. During follow-up, two patients underwent percuta- neous revascularization of the contralateral femoropopliteal axis at 5 and 8 months after EE, respectively. In both of them, the procedure was successfully performed through direct puncture of the endoarterectomized common femoral artery, without any access-site complications. Conclusions: Endarterectomy remains the gold standard in the treatment of atherosclerotic le- sions of the femoral bifurcation with excellent long-term patency rates. Furthermore, EE adds the advantages of avoiding the use of prosthetic materials in the groin and the possibility to use the treated vessels as access for further percutaneous procedures.
