多发性大动脉炎的超声诊断价值

The value of ultrasonography in the diagnosis of takayasu arteritis

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。绪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。

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 lowecho 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.
