二维及多普勒超声对头臂型大动脉炎的诊断价值

作应用二维超声显像、脉冲及彩色多普勒技术首诊９例头臂型大动脉炎，均经数字减影血管造影检查证实，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，根据血管狭窄程度不同，彩色及脉冲多普勒显示高速湍流、低速血流及无血流信号。结果表明：二维超声显像及多普勒技术对头臂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。

Diagnostic value of aortic arch syndrome by two-dimensional and Doppler ultrasonography

Nine patients with aortic arch syndrome were diagnosed by two-dimension. Pulsed wave and color Doppler echocaralography. Diagnosis of all the patients were confirmed by digital substraction angiography. Irregular thickened vessel intima and stenosis or occlusion of vessel cavity involved multiple large arteries at their origins from the aortic arch were showed by two- dimensional ultrasound.According to the different de-grees of vessel stenosis,high velocity flow turbulent,low velocity flow and no flow signal were found withDoppler echocardiography.The results demonstrated that two-dimensional and Doppler echocardiography could make a definite diagnosis for the aortic arch syndrome. It has such outstanding features as noninvasion,good repetition and so on,This can be the first method for routine diagnosis of aortoarteritis.
