经颅多普勒超声对大脑中动脉狭窄的诊断价值 　　[摘要]目的 探讨经颅多普勒超声诊断大脑中动脉狭窄的价值。方法 选取2014年6月～2017年3月在我院经颅内数字减影血管造影术确诊的30例大脑中动脉狭窄患者作为研究对象，均在术前接受经颅多普勒超声检查，观察诊断结果的准确性及狭窄程度、不同患者的大脑中动脉搏动指数、平均血流速度、收缩期分值流速。结果 经颅多普勒超声诊断出大脑中动脉轻度狭窄15例（50.00%）、中度狭窄10例（33.33%）、重度狭窄5例（16.67%），和经颅内数字减影血管造影术的诊断结果差异无统计学意义（P0.05）；大脑中动脉轻度、中度以及重度狭窄患者间的平均血流速度、收缩期分值流速差异有统计学意义（P0.05）。结论 经颅多普勒超声在大脑中动脉狭窄诊断中具有较高的应用价值。 　　[关键词]经颅多普勒超声；大脑中动脉狭窄；诊断价值 　　[中图分类号] R445.1 [文献标识码] A [文章编号] 1674-4721（2017）10（c）-0073-03 　　Diagnostic value of transcranial Doppler ultrasound in middle cerebral artery stenosis 　　HHUANG Ying1 LI Bin2 LIANG Xiang-xin3 　　1.Department of Neurology，the Affiliated Hospital of Jiujiang University，Jiangxi Province，Jiujiang 332000，China；2.Department of Ultrasound，the Affiliated Hospital of Jiujiang University，Jiangxi Province，Jiujiang 332000，China；3.Department of Stomatology，the Affiliated Hospital of Jiujiang University，Jiangxi Province，Jiujiang 332000，China 　　[Abstract]Objective To investigate the value of transcranial Doppler ultrasound in the diagnosis of middle cerebral artery stenosis.Methods 30 patients with middle cerebral artery stenosis diagnosed by transcranial digital subtraction angiography from June 2014 to March in 2017 were selected as research objects.Before surgery，they were all examined by transcranial Doppler ultrasound.The accuracy of diagnostic results，pulsatility index of middle cerebral artery，mean blood flow velocity and systolic velocity in patients with different stenosis were observed.Results By Doppler ultrasound examination，the diagnosis of mild stenosis of middle cerebral artery in 15 cases （50.00%），moderate stenosis in 10 cases （33.33%），and severe stenosis in 5 cases （16.67%） were not displayed great difference with transcranial digital subtraction（P0.05）.There were statistical differences in mean blood flow velocity and systolic velocity in patients with mild，moderate，and severe stenosis of middle cerebral artery（P0.05）.Conclusion Transcranial Doppler ultrasound is of high value in the
