title: Devices to treat peripheral chronic total occlusions.
abstract: Chronic total occlusions occur in approximately 40% of patients with peripheral vascular disease and are a difficult lesion subset to treat by endovascular approaches. The challenge lies in the difficulty in placing a wire across the site of occlusion and remaining in an intraluminal position. Conventional percutaneous transluminal balloon angioplasty for chronic total occlusions involves advancing a stiff wire through the site of obstruction, has the chance for vessel dissection and perforation, and is associated with high rates of procedural failure. Several mechanical devices have thus been developed to treat peripheral chronic total occlusions. In this article, we provide a review of the currently available devices that may increase the procedural success of treating peripheral chronic total occlusions.
