The balloon occlusion of subintimal tract (BOST) technique may be used to assist in regaining luminal re-entry in difficult cases during subintimal recanalization of chronic total occlusions in the femoropopliteal artery. Subintimal recanalization or percutaneous intentional extraluminal recanalization (PIER) is an established technique used in endovascular recanalization of chronically occluded arteries of the peripheral circulation. The primary limitation of PIER is the high technical failure rate. Failure is mainly due to the inability to re-enter the patent true lumen distal to the site of the occlusion. The BOST technique can help overcome this limitation. This chapter provides a description of the technique.
