Remote superficial femoral artery endarterectomy

The advent of minimally invasive procedures such as percutaneous transluminal angioplasty with or without stent, laser-assisted balloon angioplasty, and atherectomy, whose results have proven disappointing in the treatment of long-segment (> more than 15 cm) superficial femoral artery (SFA) occlusive disease, stimulated a reassessment of SFA endarterectomy. With the evolution of remote superficial femoral artery endarterectomy (RSFAE) a minimally invasive technique became available which could be performed through a single incision, allowed, debulking of the arterial plaque, and placement of an endovascular stent. We report results of RSFAE in an initial trial, results of RSFAE in concert with the aSpire Covered Stent which is a flexible ePTFE covered Nitinol stent with significant radial strength to withstand torsional stresses at the knee joint, and RSFAE and distal vein bypass for limb salvage.
