摘　　要：目的:分析彩色多普勒超声和CT血管造影对颈动脉狭窄患者颈动脉粥样硬化斑块的诊断价值。方法:以便利抽样法,选取2020年1月—2021年12月武穴市中医医院收治的112例(287条血管)颈动脉狭窄患者为研究对象,所有患者均接受彩色多普勒超声、CT血管造影及数字减影血管造影检查,以数字减影血管造影检查结果作为金标准,比较两种检查方式对颈动脉狭窄的诊断效果及斑块检出情况。结果:数字减影血管造影检查结果显示,112例(287条血管)患者中,轻度狭窄96条(23.30%),中度狭窄131条(45.64%),重度狭窄37条(12.89%),闭塞23条(8.01%)。CT血管造影中重度狭窄检出率为86.39%(165/191),明显高于彩色多普勒超声的76.96%(147/191)(P<0.05)。CT血管造影诊断颈动脉中重度狭窄的敏感度、准确度均高于彩色多普勒超声(P<0.05)。两种检查方式颈总动脉斑块检出数量一致,CT血管造影颈内动脉、颈外动脉斑块检出数量多于彩色多普勒超声。彩色多普勒超声颈总动脉易损斑块检出率为51.94%(214/412),高于CT血管造影检查的23.30%(96/412)(P<0.05)。结论:对于颈动脉狭窄患者,CT血管造影在颈动脉狭窄评估及颈内动脉斑块检出方面均优于彩色多普勒超声,彩色多普勒超声在颈总动脉易损斑块检出方面优于CT血管造影,临床上可根据两者优点,以提高颈动脉狭窄患者颈动脉粥样硬化斑块的诊断效果。Objective: To analyze the value of color Doppler ultrasound and CT angiography in the diagnosis of carotid atherosclerotic plaque in patients with carotid artery stenosis. Method: A total of 112 patients(287 vessels) with carotid stenosis who admitted to Wuxue Traditional Chinese Medicine Hospital from January 2020 to December 2021 were selected by convenient sampling method, all patients were given color Doppler ultrasound, CT angiography and digital subtraction angiography. The results of digital subtraction angiography were taken as the gold standard. The diagnostic effects of two examination methods on carotid stenosis and the detection of plaque were compared. Result: Digital subtraction angiography showed that among 112 patients(287 vessels), 96 vessels(23.30%) had mild stenosis, 131 vessels(45.64%) had moderate stenosis, 37 vessels(12.89%) had severe stenosis and 23 vessels(8.01%)had occlusion. The detection rate of moderate and severe stenosis of CT angiography was 86.39%(165/191), which was significantly higher than 76.96%(147/191) of color Doppler ultrasound(P<0.05). The sensitivity and accuracy of CT angiography in the diagnosis of moderate and severe carotid stenosis were significantly higher than that of color Doppler ultrasound(P<0.05). The numbers of common carotid artery plaques detected by two examination methods were the same, the numbers of internal carotid artery and external carotid artery plaques detected by CT angiography were more than those by color Doppler ultrasound. The detection rate of common carotid vulnerable plaque by color Doppler ultrasound was 51.94%(214/412), which was higher than 23.30%(96/412) of CT angiography(P<0.05).Conclusion: For patients with carotid stenosis, CT angiography is superior to color Doppler ultrasound in the evaluation of carotid stenosis and the detection of internal carotid artery plaque, and color Doppler ultrasound is superior to CT angiography in the detection of vulnerable plaques of common artery. Clinically, according to the advantages of both, we
