Interventions for Extracranial Carotid Artery Stenosis: An Update.

OPINION STATEMENT: Clinical trials demonstrate that stroke risk after the periprocedural period is similar for carotid angioplasty and stenting (CAS) and carotid endarterectomy (CEA), making CAS an acceptable alternative to CEA. However, there tends to be a higher procedural risk of stroke for CAS than for CEA and a potentially higher rate of myocardial infarction in patients undergoing CEA as compared to CAS. Furthermore, lower rates of complications with revascularization and of post-revascularization stroke have been attributed to advances in medical management, improved surgical technique, and new devices. We discuss identifying patients who may have higher complication rates and recent clinical studies and medical advances directed at reducing stroke risk in patients with extracranial carotid stenosis.
