Endovascular Treatment of Chronic Occluded Popliteal Artery Aneurysm.

Abstract

Critical limb ischemia may be the consequence of chronic occlusion of an aneurysm of popliteal artery. Endovascular repairs have the potential to be less invasive than open surgery and to allow the treatment, during the same procedure, of occlusive infrapopliteal diseases achieving a better distal outflow. Eleven patients with occluded popliteal artery aneurysm (PAA) underwent an endovascular repair of PAA using a new technique, by positioning of a Viabahn graft inside a bare nitinol stent, deployed at the level of aneurysm with the intent to avoid distal embolization and to assure an external scaffold for the Viabahn graft. Immediate success rate was 100%. A peroneal artery embolization occurred in 1 patient (9%) and was successfully treated by stent implantation. Four (36.4%) patients needed a below-the-knee revascularization to achieve at least 1 vessel line to the foot. Mean postoperative hospital stay was 2.6 days. At 24-month follow-up, primary patency, target lesion revascularization, and major amputation rates were 82%, 9%, and 0%, respectively. All patients are still alive at last follow-up visit. The endovascular repair with the combined use of a bare metal stent and Viabahn graft resulted in a low incidence of distal embolization and major amputation rate, with an excellent 24-month patency rate, and may offer a safe alternative to open surgery for the treatment of occluded PAAs.
