Bovine Pericardial Patch Closure during Femoral Artery Endarterectomy

Abstract

Objective: We report here our experience with bovine pericardial patch (XenoSure), a new material for patch angioplasty during femoral artery thromboendarterectomy (TEA). Methods: Six patients (7 limbs) treated with TEA using XenoSure from September 2020 to March 2021 were included in the study. The mean age of the patients was 73.5 years, and the male to female ratio was 5 : 1. Five patients underwent TEA under general anesthesia, 1 patient under local anesthesia, and 3 patients received hybrid endovascular therapy (EVT). Results: The ankle-brachial pressure index recovered in all patients, and ischemic leg symptoms improved. Postoperative complications included one case of lymphatic leakage and one case of superficial wound infection; both recovered conservatively. Conclusions: The use of XenoSure in TEA not only leads to preservation of autologous veins and reduction of operative time, but also could enable reliable endarterectomy without the restriction on the length of the arteriotomy. Our results indicate that XenoSure could be a useful option in TEA.
