摘　　要：目的探讨颈部血管彩色多普勒超声(CDUS)、CT血管造影(CTA)及数字减影血管造影(DSA)在颈动脉狭窄病变检测中的临床价值。方法收集230例怀疑有颈动脉狭窄病变并同时行颈部CDUS、CTA及DSA检查的患者,观察CDUS、CTA两者联合检查颈动脉血管狭窄及斑块检出的灵敏度、特异度和准确度以及与DSA检查的一致性。结果以DSA检查为金标准,CDUS联合CTA与之比较,灵敏度为89.62%,特异度为51.61%,准确度为69.13%,漏诊率为10.38%,误诊率为48.39%,阳性预测值为61.29%,阴性预测值为85.33%(χ2=44.219,P<0.01,K=0.399)。CDUS与CTA比较K=0.467,χ2=50.231,P<0.01。结论诊断颈动脉狭窄病变时,CDUS联合CTA与DSA比较,一致性不理想,两者联合可广泛用于颈动脉狭窄病变的早期筛查,但不能替代DSA检查。Objective To discuss the clinical value of carotid color Doppler ultrasound（CDUS） ,computerized tomography angi- ography（CTA） and digital subtraction angiography（DSA） using in extra cranial internal carotid artery stenosis disease examination. Methods The examinations mentioned - above were performed on 230 patients who diognosised possibly carotid artery stenosis disease, observe the sensitivity,specificity ,rate of accuracy and assess the consistency in carotid CDUS unite CTA examination compared with DSA in carotid artery stenosis disease. Results Using DSA as a golden standard, Compare carotid CDUS unite CTA to DSA,the sensitiv- ity was 89.62%, specificity was 51.61%, rate of accuracy was 69.13%, missed diagnosis rate was 10.38% and misdiagnosis rate was 48.39%, positive rate was 61.29%, negative rate was 85.33%, χ^2 = 44. 219,P 〈 0.01, K = 0.399. Compare carotid CDUS to CTA, K = 0. 467, χ^2= 50.231 ,P 〈 0. 01. Conclusion It is unsatisfactory correlativity in CDUS unite CTA compared with DSA, CDUS unite CTA can be widely used in carotid artery stenosis disease early screening, but they can＇ t replace the DSA.
