数据说 | 颅内动脉粥样硬化


颅内动脉粥样硬化性狭窄(intracranial atherosclerotic stenosisICAS)是导致缺血性卒中重要原因之一,不同人种之间差异明显,亚裔人群中颅内动脉粥样硬化性卒中患者占30%50%,北美人群中仅有8%10%[1-2]。中国脑动脉狭窄存在显著的分布特点,即颅内动脉狭窄的比例显著高于颅外动脉狭窄[3-5]

 

2014年中国症状性颅内大动脉狭窄与闭塞研究(Chinese Intracranial AtherosclerosisCICAS)结果显示中国缺血性卒中或短暂性脑缺血发作(transient ischemic attackTIA)患者中颅内动脉粥样硬化发生率为46.6%,伴有ICAS的患者症状更重、住院时间更长,卒中复发率更高,且随狭窄程度的增加复发率升高[6]
