摘要 目的:观察彩色多普勒超声在诊断不同程度颈动脉狭窄中的应用价值。方法:选择疑诊为颈部动脉狭窄的急性脑梗死住院患者45例(共178条颈动脉血管),以数字减影血管造影检查(DSA)结果为标准,比较超声检查NASCET法和截面积法诊断颈动脉狭窄的敏感度、特异性及准确度;并采用Kappa一致性检验分析超声检查和DSA检查诊断狭窄程度结果的一致性。结果:以DSA检查结果为标准,采用NASCET法超声诊断的敏感度为88.1%,特异性为93.7%,准确度为91.6%;采用截面积法超声诊断的敏感度为85.1%,特异性为91.9%,准确度69.3%。两种方法检查的敏感度、特异性、准确度比较,差异均不显著(P>0.05)。Kappa检验结果显示,超声检查与DSA检查诊断颈动脉狭窄的结果高度一致(Kappa=0.75)。结论:超声检查NASCET法和截面积法诊断颈动脉狭窄的价值相似;血管超声诊断颈动脉狭窄与DSA检查结果具有较好的一致性。
