New devices to cross chronic total occlusion in critical limb ischemia

Abstract

Chronic total occlusions (CTos) represent a technically demanding subset of lesions, which in most cases require special endovascular methods, advanced operator skills, and utilization of sophisticated assisting devices for successful treatment. CTo crossing devices offer an additional option to interventionists in the treatment of challenging lower extremity peripheral arterial occlusions. These devices may improve crossing rates, allowing delivery of therapeutic devices to the target lesion. initial technical results seem quite promising, although adequate data on patient and device selection are lacking. until long-term clinical data verify the durability of those techniques, these devices must be used in a stepwise fashion in selected patients with Cli. © 2016 Edizioni Minerva Medica
