Patients with aSAH who have undergone successful aneurysm securing will be randomly assigned to receive either aspirin plus standard care or a placebo plus standard care. The study drug will be started within 48 hours of undergone successful aneurysm securing and continued for not less than 10 days and not more than 14 consecutive days. The main goal is to compare the rate of favorable functional outcomes at 3 months between the two groups. Secondary goals include evaluating the incidence of delayed cerebral ischemia, cerebral infarction, mortality, and safety outcomes such as major bleeding events.",[123,124],"Aneurysmal Subarachnoid Hemorrhage (aSAH)","Delayed Cerebral Ischemia",[126,23,127,128,129,130],"Aneurysmal subarachnoid hemorrhage","Delayed cerebral ischemia","Antiplatelet therapy","Functional outcome","Randomized controlled trial","NOT_YET_RECRUITING","2026-06-07",{"date":134,"type":135},"2026-06-11","ACTUAL",{"date":137,"type":117},"2026-06-01",{"date":139,"type":117},"2029-08",{"name":5,"class":6},1]
