Assessment of Dual-Antiplatelet Regimen for Pipeline Embolization Device Placement: A Survey of Major Academic Neurovascular Centers in the United States

Significant heterogeneity in dual-antiplatelet regimens after PED placement and associated costs exists at major academic neurovascular centers. The most commonly used first-line dual-antiplatelet regimen consists of aspirin and clopidogrel. Two major alternate protocols involving ticagrelor and prasugrel are administered to clopidogrel hyporesponders. The optimal dual-antiplatelet regimen for patients with cerebrovascular conditions has not been established, given limited prospective data within the neurointerventional literature.
