Abstract

Background: Intra- and postprocedural thrombosis are major complication of aneurysmal coil embolization, stent-assisted coiling, and pipeline embolization. The common but unproven practice of dual antiplatelet therapy with aspirin and a P2Y12 inhibitor in neuro-endovascular patients is inferred from the cardiology literature without large clinical trials to support it in neuro-endovascular patients. Objective: We conducted an electronic survey to identify practice variations surrounding the use of oral antiplatelets in patients undergoing endovascular neuro-interventional procedures across neuro-endovascular centers in the United States. Methods: An electronic survey was distributed via the Web. Any practicing neuro-intensive care unit (ICU), neuro-interventional or stroke physician, pharmacist, physician assistant, or nurse practitioner was eligible to respond to this survey between June and October 2017. Results: A total of 33 responses were collected during the survey period. A response rate of 16% was calculated after taking into account all comprehensive stroke centers in the United States. Aspirin and clopidogrel was the standard-of-care antiplatelet regimen utilized in the majority of institutions (82%). Alternatively, 4 institutions used monotherapy (aspirin [n = 2], clopidogrel [n = 1], either aspirin or clopidogrel [n = 1]) and 2 institutions reported practitioner-dependent practices. Just under half of the centers reported ticagrelor as the primary alternative in clopidogrel nonresponders (48%). Conclusion: Dual antiplatelet therapy with aspirin and clopidogrel appears to be standard of care in this setting based on our survey. About half of responding institutions use ticagrelor in cases where clopidogrel resistance is suspected. Large society-wide patient registries are needed to provide data for future safety and efficacy studies.
