Although standardized medical management is widely used, effective treatment options for cerebral vasospasm remain limited.\n\nEndovascular treatment, including intra-arterial drug infusion and mechanical angioplasty, may relieve vasospasm and improve cerebral perfusion after aneurysmal subarachnoid hemorrhage. However, most available evidence comes from retrospective or observational studies, and high-quality randomized evidence remains insufficient. Milrinone is a phosphodiesterase inhibitor with multiple potentially beneficial effects, including vasodilation, positive inotropic activity, anti-inflammatory properties, and endothelial protection. These effects may make milrinone a promising therapeutic agent for relieving cerebral vasospasm, reducing delayed cerebral ischemia, and ultimately improving clinical outcomes after aneurysmal subarachnoid hemorrhage.\n\nThis study is a multicenter, prospective, randomized controlled clinical trial designed to evaluate whether early continuous milrinone-based endovascular therapy improves outcomes in patients with cerebral vasospasm after aneurysmal subarachnoid hemorrhage. Eligible participants will be randomly assigned to receive either standardized medical management alone or milrinone-based endovascular therapy plus standardized medical management. In the intervention group, patients will receive intra-arterial milrinone during endovascular treatment, with mechanical angioplasty when clinically indicated, followed by continuous intravenous milrinone infusion for 72 hours after intra-arterial administration.\n\nThe study will evaluate whether this continuous treatment strategy reduces poor neurological outcomes at 3 months after randomization. It will also assess the effects of treatment on delayed cerebral ischemia, vasospasm resolution, cognitive function, quality of life and so on. The results of this trial may provide high-quality evidence for early continuous milrinone-based endovascular therapy as a treatment strategy for cerebral vasospasm after aneurysmal subarachnoid hemorrhage.",[123,124],"Subarachnoid Hemorrhage, Aneurysmal","Cerebral Vasospasm After Subarachnoid Hemorrhage",[126,127,128,129,130],"aneurysmal subarachnoid hemorrhage","Cerebral vasospasm","Milrinone","Endovascular Therapy","Outcomes","2026-06-25",{"date":133,"type":134},"2026-06-29","ACTUAL",{"date":136,"type":134},"2026-06-03",{"date":138,"type":117},"2029-12-31",{"name":5,"class":6},2]
