【摘要】 目的:探讨多发性大动脉炎外周血管病变的超声表现,提高对本病的认识。方法:采用美国泰索尼彩色多普勒超声诊断仪,探头频率10MHz,对9例大动脉炎患者外周血管进行二维及彩色多普勒超声检测。结果:9例大动脉炎患者受累血管分布为头臂动脉7例,其中锁骨下动脉7例,颈总动脉6例,腹主动脉2例,肾动脉2例,混合型2例。表现为病变动脉管壁不规则增厚、管腔狭窄或闭塞。根据狭窄程度不同,彩色多普勒呈高速湍流、低速血流及无血流信号。结论:超声诊断多发性大动脉炎外周血管病变有确切的价值,可作为临床诊断多发性大动脉炎的首选方法。更多还原

【Abstract】 Objective:To explore morphology of peripheral vessel in takayasu’s arteritis so as to improve our understanding of this disease.Methods:By DIASONICS color ultrasound,transducer frequency 10 MHz,9 patients of takayasu’s arteritis were diagnosed by duplex and color doppler ultrasonography.Results:Among 9 cases,peripheral arteries were involved including in 7 brachiocephalic arteries(7 subclavian and 6 common carotid),2 abdominal aorta,2 renal arteries,2 mixed type.Aorticarch vascular lesions displayed irregular thickening intima and stenosis and occlusion with 2-D ultrasound,turbulent flow in high velocity,flow in low velocity and no flow signals with color doppler ultrasonnography.Conclusion:Ultrasonographic diagnosis is valued on peripheral vessels in takayasu’s arteritis,which can be the first method for routine diagnosis of takayasu’s arteritis.更多还原
