摘要 目的通过研究缺血性脑卒中并颈内动脉迂曲患者的脑血流动力学变化,探讨缺血性脑卒中和颈内动脉迂曲的相关性。方法选取我院收治的缺血性脑卒中伴双侧颈内动脉迂曲患者50例为双侧组,单侧颈内动脉迂曲患者50例为单侧组,并选取同期双侧颈内动脉正常患者50例设为正常组。三组患者均行磁共振血管成像(MRA)及经颅多普勒超声(TCD)后联合确诊为颈内动脉迂曲,并以TCD行血流动力学评估,比较三组患者颅内血流动力学变化。结果单侧组迂曲侧和非迂曲侧大脑中动脉平均血流速度(Vm)、收缩期峰速(Vs)、舒张末期流速(Vd)、搏动指数(PI)比较差异无统计学意义(P>0.05);双侧组Vm、Vs、Vd、PI明显低于正常组(P<0.05)。结论颈内动脉迂曲可引起颅内血流动力学变化,在一定状态下,严重的动脉迂曲可能是缺血性脑卒中相关因素之一。
