超声诊断多发性大动脉炎外周动脉病变的价值

目的 探讨超声诊断多发性大动脉炎外周动脉血管病变的价值。方法 采用Aeuson 128 XP 10型彩色超声诊断仪，探头频率5．0～7．5MHz，对33例多发性大动脉炎患者外周血管进行二维超声及彩色多普勒超声检查，分析病变动脉的二维及彩色多普勒声像图指标。结果 33例大动脉炎患者受累血管分布为：颈总动脉21例，锁骨下动脉14例，腹主动脉5例，肾动脉11例，股动脉1例，髂外动脉1例。病变血管壁厚度2．0～5．2mm。管腔不同程度狭窄或闭塞并出现盗血现象。结论 超声检查可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，是诊断大动脉炎的有力手段，可作为临床诊断多发性大动脉炎的常规方法。

Diagnostic Value of Color Doppler Ultrasonography for Peripheral Arterial Lesions in Patients with Aorto-arteritis

Objective To evaluate the effects of color Doppler sonography for the diagnosis of peripheral arterial lesions in patients with aorto-arteritis.Methods Acuson 128 XP 10 ultrasonic device with transducer frequency 5.0-7.5 MHz was applied.The lesions of peripheral arteries in 33 cases with aorto-arteritis were scanned with 2-D sonography.Results In 33 cases with aorto-arteritis,the peripheral lesions were:common carotid artery(21 cases),subclavicular artery(14 cases),abdominal aorta(5 cases),renal artery(11 cases),femoral artery(1 case) and external iliac artery(1 case).The thickness of the arterial wall was 2.0-5.2 mm,luminal stenosis or occlusion was in various degrees and blood steal syndrome occurred occasionally.Conclusions Color Doppler ultrasonography can play a key role in the diagnosis of aorto- arteritis with multiple peripheral arteritis.
