Application of Platelet Function Test in Prevention of Ischemic Events After Stent Placement in Intracranial Aneurysms

This study was designed to identify high platelet reactivity (HPR) who might have in-stent thrombosis in unruptured aneurysm with intracranial stent placement with light transmittance platelet aggregometry (LTA). For HPR patients, higher ischemic stroke rate maybe occurred, and we hypothesis that dose adjustment of aspirin and clopidogrel based on LTA monitoring maybe reduces the rate of ischemic stroke compared to a standard strategy after intracranial stent implantation at early periprocedural period and 1 month follow-up period.
