TCCD技秘断急ffitt幽薛中蹒的濒跋析
【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月一2023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，
P0.05o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性，其相应的指标可对评估
患者的病情具有参考价值。
