彩色多普勒超声诊断主动脉夹层的临床意义

目的 探讨经胸彩色多普勒超声对主动脉夹层诊断的临床应用价值.方法 对采用彩色多普勒超声检查诊断的12例主动脉夹层患者进行回顾性总结分析.结果 12例主动脉夹层患者超声图像清晰显示局部主动脉扩张,主动脉壁分离呈双层离散回声,主动脉腔内显示一条回声带,假腔形成,真腔变窄,真腔内血流增速,血流显色明亮混乱,部分假腔内显示血栓回声及暗淡血流信号.结论 彩色多普勒血流显像对主动脉夹层的诊断及鉴别诊断有重要临床意义,可作为确诊和筛查主动脉夹层的首选诊断技术.

Clinical Significance of Color Doppler Ultrasonography Diagnosing Aortic Dissecting Aneurysm

Objective To explore the value of color Doppler ultrasonography in diagnosing aortic dissecting aneurysm. Methods 12 cases of aortic dissecting aneurysm were analysed by color Doppler ultrasonography. Results In all patients, the sonograrn clear display the diameters of partial aorta widened, the echo of lacerated intima flaps showed in the aortic wall,the false lumen formed and the true lumen narrowed,which could disclose the change of blood flow signals in the true and false lumens. Conclusions Color Doppler ultrasonography is useful in diagnosis of aortic dissective aneunysm and can be used as the preferred diagnostic technique.
