彩色多普勒超声在颈动脉狭窄诊断中的应用

目的：探讨彩色多普勒超声在颈动脉粥样硬化诊断中的优势。方法对临床疑似诊断为颈动脉粥样硬化的患者156例行彩色多普勒超声检查与 DSA、mRA 及 CTA 等检查。结果156例患者中阳性结果150例，其中颈动脉粥样硬化149例，多发性大动脉炎1例，正常6例。结论彩色多普勒超声可以清晰显示颈动脉管壁的结构，检出颈动脉硬化斑块和血栓，鉴别稳定和不稳定斑块（包块溃疡斑块），准确判断颈动脉狭窄的程度和范围，为临床预防和治疗方案的选择提供客观依据，是一种无创、实时、敏感、准确、可重复的诊断方法。

The application of color doppler ultrasonography in the diagnosis of carotid atherosclerosis

Objective To evaluate the advantage of color doppler ultrasonography in the diagnosis of carotid athero-sclerosis. Methods 156 patients who were clinically suspected with carotid atherosclerosis were examined by ultrasonography, DSA,mRA and CTA . Results 150 patients had positive results in all the patients,and there were 149 cases with carotid ath-erosclerosis and 1 case with Takayasu among them. The other 6 cases were normal. Conclusion Color doppler ultrasound can clearly show the structure of carotid arteries,carotid atherosclerotic plaque and thrombus. It also can identify the stable and un-stable plaque（including ulcerated plaque）,accurately determine the degree and range of carotid artery stenosis and provide objective evidence for doctor to select prevention and treatment programs,which is a non-invasive,real-time,sensitive,accurate and reproducible diagnosis method.
