Urgent Treatment for Symptomatic Carotid Stenosis: The Pittsburgh Revascularization and Treatment Emergently After Stroke (PIRATES) Protocol

Neurosurgery. 2020 Sep 15;87(4):811-815. doi: 10.1093/neuros/nyaa096.

Abstract

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.
