【摘要】目的:探讨对急性缺血性脑卒中颈动脉狭窄患者采用TCCD技术诊断的准确性及参数分析。方法:选取我院收治的急性缺血性脑卒中患者作为研究对象,其样本量按照该疾病收治总量的百分比进行估算,从中选取84例(2022年4月—2023年2月),对患者进行数字减影检查(DSA)以及经颅彩色多普勒超声检测(TCCD),对其结果进行分析。结果:84例患者经DSA检查后,其中52例患者为轻中度狭窄,29例为重度狭窄,3例为闭塞,TCCD检查结果与其一致性较高(Kappa=0.865);随着狭窄程度的增加,患者各项TCCD参数均发生明显变化,其中舒张末期血流速度(EDV)、收缩期峰值流速(PSV)以及平均血流速度(MV)呈下降趋势,搏动指数(PI)呈上升趋势,P0.05。结论:对急性缺血性脑卒中颈动脉狭窄患者采用TCCD技术诊断具有较高的准确性,其相应的指标可对评估患者的病情具有参考价值。
