摘　　要：目的:探讨颈部血管彩色多普勒超声对颈内动脉颅外段狭窄病变的诊断价值。方法:对2006年7月至2009年10月在西京医院行全脑血管造影及颈部血管彩超检查的506例缺血性脑血管病患者进行回顾性分析,其中颈内动脉狭窄或闭塞的98例,以DSA为金标准分析颈部血管彩超诊断颈内动脉颅外段的灵敏度、特异度,并对不同狭窄程度的颈内动脉的检出情况进行比较。结果:颈部血管彩超检测颈内动脉狭窄或闭塞的灵敏度为74.6%,特异度为99.4%,准确率为96.4%,漏诊率为25.4%,误诊率为0.56%。对轻度颈内动脉狭窄的检出,颈部血管彩超与DSA相比有统计学差异,而对于中重度狭窄及闭塞的检出,两种方法相比没有统计学差异。结论:颈部血管彩超可广泛用于颈内动脉颅外段病变的早期筛查。Objective：To discuss the clinical value of carotid color Doppler ultrasound using in extra cranial internal carotid artery stenosis disease examination.Methods：From July,2006 to October,2009,the arteries of 506 patients with ischemic cerebrovascular disease examining by DSA or carotid duplex ultrasound were analyzed retrospectively,98 cases of them were ICA stenosis.The sensitivity and specificity of extra cranial ICA were analyzed by carotid duplex ultrasound examination using DSA as a golden standard.The examined situation were compared in vary stenosis degrees.Results：The sensitivity of carotid duplex ultrasound in examining ICA stenosis was 74.6%,specificity was 99.4%,rate of accuracy was 96.4%,missed diagnosis rate was 25.4% and misdiagnosis rate was 0.56%.To examine mild ICA stenosis patients,DSA and carotid duplex ultrasound have statistical difference.To examine moderate and severe ICA stenosis patients,DSA and carotid duplex ultrasound have no statistical difference.Conclusion：Carotid duplex ultrasound can be widely used in extra cranial internal carotid artery disease early screening.
