多发性大动脉炎的超声诊断价值

目的探讨多发性大动脉炎的二维及彩色多普勒超声图像特点,提高超声对本病诊断的准确性。方法对29例多发性大动脉炎患者病变段血管进行二维及彩色多普勒超声检查,分析病变段血管的声像图改变。结果29例多发性大动脉炎患者中头臂型15例,混合型12例,肾动脉型1例,胸腹主动脉型1例,病变段血管内壁增厚,回声减低,致管腔不同程度狭窄,为21%~95%。并发锁骨下动脉盗血综合征2例,颈总动脉闭塞8例。结论多发性大动脉炎累及血管最多为头臂型,其次为混合型。二维及彩色多普勒超声检查病变段血管的形态学及血流动力学改变,可作为临床诊断多发性大动脉炎的常规方法。

The value of ultrasonography in the diagnosis of takayasu arteritis

Objective To investigate the value of ultrasonography in the diagnosis of akayau arteritis.Methods The lesions of peripheral arteries in 29 cases with Takayasu arteritis were scanned with 2-D color doppler and sonography.Results Among 29 cases,the peripheral lesions include head-arm artery type (15 cases),diffuse artery type (12 cases),renal artery type (1 case) and abdominal aorta type (1 case).The ultrasonic characters of the lesions were listed as diffused thickening of intima-media (IMT) and low-echo and stenosis of involved vasculars.The extent the stenosis with 21%~95% with occlusion of artery in subclavian (2 cases) and common carotid arteries (8 cases).Conclusion The ultrasound revealed characters of Takayasu arteritis,and the degree of stenosis could be determined with color Doppler ultrasonic examination.
