Periprocedural drug therapy in carotid artery stenting: the need for more evidence

Vascular. 2008 Nov-Dec;16(6):303-9. doi: 10.2310/6670.2008.00081.

Abstract

Carotid artery stenting (CAS) is a widely accepted alternative for patients at high risk for carotid endarterectomy (CEA). However, the role, indications, and evidence for many pharmacologic agents that are used adjunctively in the periprocedural setting have not been established. Several drugs are commonly used before, during, and after CAS, but their uses have not been standardized. Large prospective cohort studies with good validity or randomized trials are needed to demonstrate efficacy, predict outcome, and determine the optimal use of these medications in patients undergoing CAS to improve patient care and obtain optimal outcomes. Several conclusions can be made: (1) dual-antiplatelet therapy (aspirin and clopidogrel) is commonly used for CAS; (2) the most commonly used regimen is aspirin 325 mg and clopidogrel 75 mg per day, but the optimal time of therapy is unknown; and (3) the dose and regimen of other agents used for CAS are not established.
