摘要 目的分析探讨大脑中动脉粥样硬化性狭窄(middle cerebral artery syndrome,MCAS)患者脑血管运动反应性,总结其脑血管自动调节能力对缺血性卒中发生的预警价值。方法选取中山市中医院30例有症状及30例无症状MCAS患者作为研究组,另选取60例健康人作为对照组,所有研究者均行多普勒超声检查,比较2组受检者屏气前、屏气末双侧MCA血流速度及屏气时长,计算屏气指数。结果研究组患者均伴有不同程度的狭窄病变。研究组病变患者BHI指数明显低于对照组健康人,差异有统计学意义(P<0.05);重度狭窄病变患者指标明显低于轻度与中度病变患者,差异有统计学意义(P<0.05);轻度病变患者与对照组健康人指标比较,差异无统计学意义。结论无症状或有症状MCAS患者脑血管自动调节能力均伴有明显下降,及时检测患者脑血管自动调节能力可以为缺血性卒中预防提供指导。
