研究目的: |
本研究的目的是在多个中心进行前瞻性随机对照研究,用于评估急诊机械取栓后残留的颅内动脉狭窄即刻行血管成形术/支架置入术相比于单纯取栓,是否能改善卒中预后(90天mRS评分),为今后急性缺血性脑卒中血管内治疗方案提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
This prospective, randomized, multicenter study is performed to assess whether immediate angioplasty/stenting of residual intracranial arterial stenosis after emergency mechanical thrombectomy improves the prognosis of stroke (90-day mRS score), and to provide a basis for the choice of endovascular treatment of acute ischemic stroke in the future. |
