摘　　要：目的评价多普勒超声技术(CDFI)与数字减影血管造影(DSA)诊断颈动脉粥样硬化狭窄的临床应用价值。方法对185例缺血性脑血管病患者的颈动脉CDFI和DSA检查结果进行性回顾性分析,其中短暂性脑缺血发作(TIA)患者76例,脑梗死患者109例。结果 185例患者中,CDFI与DSA检查均发现梗死组颈动脉狭窄高于TIA组(P<0.05);以DSA诊断为标准,CDFI检查颈动脉颅外段动脉狭窄与DSA相比较,轻度狭窄、中重度狭窄、闭塞及总符合率分别为86.21%、98.82%、65.96%和86.96%。结论 CDFI对于血管轻度狭窄和闭塞的诊断欠佳,尚不能取代DSA检查;CDFI联合DSA可用于颈动脉狭窄的筛选和随访。Objective To evaluate the clinical application of color doppler flow imaging （CDFI） and digital subtraction angiography （DSA） in diagnosis of carotid artery stenosis （CAS）. Methods Duplex ultrasonography and DSA findings in 185 patients with ischemie cerebral vascular diseases were retrospectively analyzed. Value of duplex ultrasonography for the diagnosis of CAS was assessed. They were divided into transient ischemie attack （ TIA, n = 76） and cerebral infarction group （ n = 109 ）. Results Both of the ultrasound and DSA found that the incidence of carotid artery stenosis in cerebral infarction was higher than that in TIA （ P 〈 0.05 ）. Taking DSA as standard, the accordance rate of ultrasound in diagnosing mild stenosis, moderate and severe stenosis, clot and both of them were 86.21% , 98.82% , 65.96% and 86.96% , respectively. Conclusion CDFI is poor for the diagnosis of mild stenosis and clot of carotid artery therefore cannot replace DSA. With combination of two methods, it is important significance in the diagnosis of filtering and follow - up in patients with carotid artery stenosis.
