Update of carotid stent trials.

As is the case in many vascular territories, endovascular treatment of extracranial carotid artery disease is becoming a rival alternative to surgery. Results of carotid artery stenting (CAS) are improving with the introduction of embolic protection devices, improved technology, and increasing operator experience. Multiple clinical studies have shown results in favor of CAS as opposed to carotid endarterectomy (CEA) in patients considered at high risk for surgery. Current ongoing trials are examining both treatment options in low and intermediate risk patients in prospective randomized protocols. With the recent FDA approval of carotid stent systems, we are entering a new era in the treatment of carotid artery disease. An update of modern carotid stent studies, as well as stent versus surgery studies in the current era is needed.
