研究目的:

选取有症状的中重度颅内动脉粥样硬化性狭窄或闭塞且脑血流灌注下降(CTP脑灌注分级2、3级或SPECT脑血流储备I、II级)的患者,随机分为手术组和药物组,比较手术组与药物组治疗前后的脑血流灌注改变、缺血卒中总发生率的情况。  

Objectives of Study:

Patients with symptomatic intracranial arteries atherosclerotic stenosis and decreased cerebral blood perfusion (CTP cerebral perfusion grade 2, 3 or SPECT cerebral blood flow reserve grade I and II) will be randomly divided into the surgery group and the drug group, and we will compare the changes in cerebral blood perfusion and the total incidence of ischemic stroke of two groups.
