主动脉夹层动脉瘤的超声诊断

Echocardiography Diagnosis of Aortic Dissecting Aneurysm

目的 探讨主动脉夹层动脉瘤的超声特点。 方法 对 16例临床疑为主动脉夹层的患者进行超声心动图、CT及 MRI检查。 结果 心脏超声检查检出率 92 .3% (14 / 16 ) ,特点为 (1)主动脉壁有分离的回声带 ,真假腔血流速度不同 ;(2 )升主动脉增宽 4 2～ 5 6 m m(13/ 16 ) ;(3)夹层远心端形成血栓 (2 / 16 )。

Objective\ To analyze the characteristic of the echocardiography diagnosis of aortic dissecting aneurysm.\ Methods\ 16 cases aortic dissecting aneurysm had examined by X\|ray, echocardiogragh, CT and MRI.\ Results\ The sensitivity detected with echocardiography was 92.3%.\ The characteristics of the imaging were as the following: (1)aortic wall possessed two discrete echo bands.\ Fine cavity and false cavity possessed two kind blood flow stream; (2)enlarged the aortic cavity(42~56 mm); (3)formation of throm...
