目的探讨彩色多普勒超声对主动脉夹层动脉瘤的临床诊断价值。方法观察各房室大小形态、主动脉宽度、主动脉内有否异常隔膜回声及血流情况。结果彩超对夹层动脉瘤诊断的敏感性和特异性较高,可直接显示主动脉内的带状隔膜,并将主动脉分为真假两腔,腔内隔膜运动及血流情况均清晰可见。结论彩色多普勒超声对主动脉夹层动脉瘤有独特的诊断价值,可作为临床首选检查方法。
Objective To investigate the value of color Doppler ultrasound in the diagnosis of aortic dissection aneurysm. Methods To observe the size and shape of atrioventricular space, aortic width, abnormal aortic echo and blood flow in the diaphragm. Results The sensitivity and specificity of color Doppler ultrasound in the diagnosis of dissecting aneurysms are high. It can directly display the diaphragm in the aorta and divide the aorta into true and false two cavities. The motion and blood flow in the cavity are clearly visible. Conclusion Color Doppler ultrasound has a unique diagnostic value for aortic dissection aneurysm, which can be used as the first choice of clinical examination.
