Carotid angioplasty and stenting: evolution and current status.

The management of carotid stenosis is in evolution. Carotid endarterectomy has been the gold standard for the treatment of carotid stenosis for many years. However, recently, carotid angioplasty and stenting has emerged as a feasible and relatively safe management alternative. The appropriate clinical setting for its preferential use over carotid endarterectomy continues to be the subject of ongoing clinical trials. In this article, we review the evolution of carotid angioplasty and stenting, the evidence behind the current indications, and limitations of this procedure, as well as provide an overview of preprocedural evaluations and periprocedural management.
