Comparison of the Antiplatelet Efficacy of Aspirin Combined With Clopidogrel and Aspirin Combined With Half-dose Ticagrelor in Patients With Unruptured Intracranial Aneurysms With Normal CYP2C19 Metabolizer Phenotype

Summary

The goal of this clinical trial is to compare the antiplatelet efficacy of aspirin combined with clopidogrel and aspirin combined with half-dose ticagrelor in in patients with unruptured intracranial aneurysms with normal CYP2C19 metabolizer phenotype. The main questions it aims to answer are: If aspirin combined with half-dose ticagrelor is comparable to or better than aspirin combined with clopidogrel? What medical problems do participants have when taking aspirin combined with half-dose ticagrelor? Researchers will compare aspirin combined with half-dose ticagrelor to aspirin combined with clopidogrel to see if aspirin combined with half-dose ticagrelor works to treat patients with unruptured intracranial aneurysms received endovascular treatment. Participants will: Take aspirin combined with half-dose ticagrelor or aspirin combined with clopidogrel every day for 6 months Visit the clinic 1 month and 6 months for checkups and tests
