多发性大动脉炎的彩色多普勒超声诊断价值

The Value of Color Doppler Ultrasonic Examination in the Diagnosis of Multi-Takayasu Arteritis

目的探讨多发性大动脉炎的二维及彩色多普勒超声特征.方法回顾分析昆明医科大学附属延安医院影像科14例经临床证实的多发性大动脉炎患者周围血管和心脏的彩色多普勒超声影像资料.结果 (1)病变段动脉内膜-中层弥漫性增厚,回声偏低,管腔狭窄或闭塞,病变段与非病变段分界清晰,彩色多普勒显示相应的血流动力学改变;(2)受累心脏心腔增大,室壁增厚、运动减弱,左心室收缩、舒张功能减低.结论彩色多普勒超声可实时、准确、直观地显示多发性大动脉炎患者受累血管及心脏的病变性质、范围和程度,是临床诊断多发性大动脉炎的首选检查方法.

Objective To explore the characteristics of two dimensional and color Doppler ultrasonic examination in the diagnosis of multi-Takayasu arteritis. Method Color Doppler ultrasonic images of the peripheral vascular and heart were retrospectively analyzed in 14 cases with multi-Takayasu arteritis proved by clinical manifestation. Results（1） The ultrasonic characteristics of the lesions were listed as diffused thickening of intima-media（IMT）, low-echo and stenosis or occlusion of the involved vessels,clear demarcation between lesion segments and non-lesion ones, the respective changes of the blood rheology revealed by the color Doppler.（2） The increasement of the affected heart chamber, thickening and motion abatement of ventricular walls,abatement of left ventricular diastolic and systolic function. Conclusion The color Doppler ultrasound can reveal lesion characteristics,extent and degree of cases with this disease accurately and visually in real time,is the first choice for diagnosis of multi-Takayasu arthritis in clinic.
