Background
Perioperative dual‐antiplatelet therapy for flow diversion limits thromboembolic complications. However, resistance to dual‐antiplatelet therapy medications remains a concern for neuroendovascular intervention. To date, there is no standardized approach for resistance to ADP receptor antagonists.
Methods
We report a case of ticagrelor resistance for flow diversion of an intracranial aneurysm treated with vorapaxar, as well as a narrative review of the literature for previous cases of ticagrelor resistance.
Results
Flow diversion with the Pipeline embolization device was deployed for a left internal carotid artery blister aneurysm and bilateral internal carotid artery dissecting pseudoaneurysms. The patient had 3 thromboembolic complications while on dual‐antiplatelet therapy with ticagrelor or prasugrel, leading to transition of antiplatelet therapy to vorapaxar. At 84 days follow‐up, the patient was fully recovered with complete occlusion of the aneurysms.
Conclusion
Our case suggests that vorapaxar is a promising alternative for patients with ticagrelor resistance in flow diversion–treated intracranial aneurysms. High‐quality randomized controlled trials are needed to elucidate the safety and efficacy of vorapaxar in neuroendovascular procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
