摘　　要：目的对41例主动脉夹层动脉病变患者超声检查情况的分析,探讨超声检查方法在大血管病变诊断中的应用价值和临床意义.方法通过超声波血管扫描与MRI、CT血管显像,通过观察主动脉根、升主动脉、主动脉弓、胸降主动脉和腹主动脉及其主要分支动脉情况的对照分析,揭示超声检查在大血管病变诊断中的应用价值临床意义.结果 (1)彩色多普勒超声检查的敏感度和特异度分别为75.6%和100%;(2)彩色多普勒大血管扫描可以显示内膜破口,假腔,以及假腔内血流;(3)彩色多普勒大血管扫描,能清楚显示主动脉瓣关闭不全、心包积液(积血),同时可评价心脏各房室大小及心脏功能等,为临床提供有价值的信息,在此方面超声有较大的优势.结论超声技术已在临床上广泛应用,简便、安全、快速加上检查费用低廉,可作为一种理想的随诊工具.Objective To discuss the application value and clinical significance of ultrasound examination in the diagnosis of large vascular lesions through analyzing the ultrasound examination situation in 41 patients with aortic dissection artery disease. Methods Through the ultrasonic vascular scan and MRI, CT vascular imaging, we observed the aortic root, ascending aorta, aortic arch, chest descending aorta and abdominal aorta and its main branch artery, then revealed the application value and clinical significance of ultrasound examination in the diagnosis of large vascular lesions. Results （1） Color doppler sensitivity and specificity rates were 75.6% and 100%. （2） Color doppler big vascular scanning could display intima breach, the false lumen, and false lumen blood flow. 3, Color doppler lavge vascular scanning, could clearly display aortic incompetence, pericardial effusion （hemorrhage） , at the same time could evaluate the size of cardiac atria and ventricles and cardiac function, etc., provide valuable information for clinic, and had special superiority. Conclusion Ultrasound technology has been widely applied in clinic, is simple, safe, fast and economic, and can be used as a kind of ideal follow-up tool.
