The pipeline embolization device (PED) necessitates dual antiplatelet therapy (APT) to decrease thrombotic complications while possibly increasing bleeding risks. The role of APT dose, duration, and response in patients with hemorrhagic and thromboembolic events warrants further analysis. ⋯ High dose ASA >6 months is associated with fewer permanent thrombotic and hemorrhagic events. Clopidogrel therapy ≤6 months is associated with higher rates of thrombotic events. Loading doses of ASA and clopidogrel were associated with a decreased incidence of hemorrhagic events. PFT did not have any significant association with symptomatic events.
