多发性大动脉炎外周血管的超声诊断

目的 探讨多发性大动脉炎外周血管病变的超声表现。方法 采用美国GE公司生产的VIVID3彩色多普勒超声诊断仪。探头频率7.5MHz，对10例多发性大动脉炎患行二维及多普勒超声检查。结果 大动脉炎患受累血管分布为头臂动脉9例，其中锁骨下动脉9例，颈总动脉8例；腹主动脉5例，肾动脉3例，肺动脉1例，病变血管壁厚度2．0～5.0mm，管腔不同程度狭窄、闭塞及出现盗血现象。结论 超声诊断可较全面显示多发性大动脉炎形态学改变并可了解其血流动力学改变，应作为临床诊断多发性大动脉炎常规方法。

Ultrasonographic diagnosis on peripheral vessels in patients with aortoarteritis

Objective To explore the morphology of peripheral vessel in 10 aortoarteritis (Takayasu's arteritis) patients. Methods GE VIVID 3 computed sonography 7.5 MHz. 10 patients with aortoarteritis were diagnosed by duplex and color Doppler ultrasonography. Results Among 10 aortoarteritis patients, peripheral arteries involved including in 9 brachiocephalic arteries (9 sub-clavian and 8 common carotid), 5 abdominal aorta, 3 renal arteries, 1 pulmonary artery. The thickness of the involved artery wall was 2.0-5.0mm, involved vessels had charged in thickened vessel and stenosis or occlusion of vessel cavity. Conclusion Ultrasonography can be the method of routine diagnosis of aortoarteritis, because it can show the change of morphology and blood dynamics.
