Are symptomatic patients appropriate candidates for carotid artery stenting? No (at least not at present)

Most symptomatic patients should not be candidates for carotid artery stenting (CAS); at least not at present. In these patients, CAS is associated with higher stroke, as well as recurrent stenosis rates compared with carotid endarterectomy (CEA). Furthermore, CAS is considerably more expensive than CEA. These facts raise the question, why perform CAS in symptomatic patients when you have CEA, which is associated with lower stroke and recurrent stenosis rates, and is also a more cost-effective option. This article supports the theory that currently most symptomatic patients are not appropriate candidates for CAS.
