Urgent Treatment For Symptomatic Carotid Stenosis: The Pittsburgh Revascularization And Treatment Emergently After Stroke Protocol

BACKGROUND: Patients with symptomatic carotid stenosis remain at high risk of early recurrent stroke without revascularization. This risk must be balanced against a higher rate of periprocedural complications associated with early revascularization.OBJECTIVE: To analyze prospectively recorded data from an institutional protocol that standardized the urgent (<48 h) treatment of patients presenting with symptomatic carotid stenosis and underwent either carotid stenting (CAS) or carotid endarterectomy (CEA).METHODS: All patients presenting over 28 mo to a comprehensive stroke center with symptomatic carotid stenosis within 48 h of index event were screened for inclusion. All patients were given dual-antiplatelet therapy. If there was clinical equipoise between CEA and CAS, patients underwent angiography and subsequently revascularization if digital subtraction angiography demonstrated >= 50% stenosis. The primary outcome was a composite of stroke or death within 30 d.RESULTS: This study included 178 patients with a diagnosis of recently symptomatic carotid stenosis; 120 patients (67%) met the criteria. A total of 59 patients underwent CEA and 61 patients underwent CAS. There were not significant differences in the primary outcome; 3 patients (5.1%) in the CEA arm and 3 patients (4.9%) in the CAS arm met the primary outcome.CONCLUSION: In this prospective analysis, urgent revascularization for symptomatic carotid stenosis can be done with equivalently low rates of stroke or death, regardless of revascularization strategy.
