超声造影检查在诊断颈动脉狭窄中的应用价值

The value of contrast-enhanced ultrasound in the diagnosis of carotid artery stenosis

目的:评价超声造影检查在诊断颈动脉狭窄中的应用价值。方法:选取河北北方学院附属第二医院接诊的疑似颈动脉狭窄患者76例作为研究对象。对这些患者均进行彩色多普勒超声检查和超声造影检查。然后比较对这些患者进行彩色多普勒超声检查与超声造影检查所得颈总动脉(CCA)、颈内动脉(ICA)、椎动脉(VA)的血流量、脑血流量及用彩色多普勒超声检查与超声造影检查诊断其病情的准确率、敏感度和特异度。结果:1)对这些患者进行彩色多普勒超声检查与超声造影检查所得CCA、ICA、VA的血流量、脑血流量相比,P>0.05。2)与采用彩色多普勒超声检查相比,用超声造影检查诊断这些患者病情的特异度、准确率和敏感度均更高,P<0.05。结论:超声造影检查在诊断颈动脉狭窄中的应用价值较高。

objective:to evaluate the value of contrast-enhanced ultrasound in the diagnosis of carotid artery stenosis.Methods:76 patients with suspected carotid artery stenosis admitted to the second affiliated hospital of hebei north university were selected as the study subjects.All the patients underwent color doppler ultrasound and contrast-enhanced ultrasound.The accuracy,sensitivity and specificity of color doppler ultrasound and contrast-enhanced ultrasound in the diagnosis of common carotid artery(CCA),internal carotid artery(ICA),vertebral artery(VA)and cerebral blood flow were compared in these patients.Results:1)compared with the blood flow and cerebral blood flow of CCA,ICA and VA obtained by ceus in these patients,P>was 0.05.2)the specificity,accuracy and sensitivity of ceus in the diagnosis of these patients were higher than that of color doppler ultrasound(P<0.05).Conclusion:contrast-enhanced ultrasonography is of high value in the diagnosis of carotid artery stenosis.
