Multicenter Study Comparative Study
A Multicenter Cohort Comparison Study of the Safety, Efficacy, and Cost of Ticagrelor Compared to Clopidogrel in Aneurysm Flow Diverter Procedures.
Thromboembolic and hemorrhagic complications are among the most feared adverse events in the endovascular treatment of aneurysms, and this is particularly the case for flow diverter devices. Dual antiplatelet therapy has become standard of care; however, the safety, efficacy, and cost profiles of newer antiplatelet agents are not well characterized in the neurovascular context. ⋯ Ticagrelor is a safe and effective agent for prevention of thromboembolic complications following flow diverter deployment when compared to clopidogrel. However, ticagrelor remains significantly more expensive than clopidogrel, and, thus, we would advise ticagrelor be reserved for patients who are hyporesponsive to clopidogrel.
