摘要
目的:探讨彩色多普勒超声诊断头壁型大动脉炎的临床价值.方法:用Aspen彩色超声诊断仪,探头频率7～10MHz,对20例头壁型大动脉炎患者进行二维与彩色多普勒超声检查.结果:二维超声显示主动脉弓分支多条血管病变,表现为血管内膜不规则增厚、管腔狭窄或闭塞,根据狭窄程度不同,彩色多普勒呈高速湍流、低速血流及无血流信号.结论:彩色多普勒超声对头壁型大动脉炎有确诊价值,且有无创、重复性好等优点,可作为诊断大动脉炎常规首选检查方法.
Objective： To evaluate the clinical value of color Doppler ultrasonography in the diagnosis of aortic arch syndrome. Methods：20 patients with aortic arch syndrome performed 2D and color Doppler ultrasonography by Aspen color ultrasonic diagnostic apparatus with transducer frequency 7 to 10 MHz. Results：Aortic arch vascular lesions displayed irregular thickening intima and stenosis and occlusion with 2D ultrasound, turbulent flow in high velocity, flow in low velocity and no flow signals with Doppler ultrasonography. Conclusion：Color Doppler ultrasonography plays an important role in diagnosis of aortic arch syndrome,without trauma and with good repetitiveness. It may be the first method for routine examinations for aorto- arteritis.
