彩色多普勒超声诊断锁骨下动脉窃血综合征

Diagnosis of subclavian steal syndrome with color Doppler ultrasonography

目的探讨彩色多普勒超声对锁骨下动脉窃血综合征的诊断价值。方法应用彩色多普勒超声观测颈动脉、颅内外段椎动脉、锁骨下动脉、无名动脉、基底动脉及大脑后动脉的声像图特征及血流动力学的状况。结果锁骨下动脉窃血综合征主要由动脉粥样硬化和多发性大动脉炎所致,且两种原因在年龄组成、性别分布、好发部位上差异有统计学意义。锁骨下动脉窃血综合征患侧血供的代偿主要来自对侧的椎动脉。结论彩色多普勒超声对绝大多数锁骨下动脉窃血综合征可明确诊断。

Objective To evaluate the diagnostic value of color Doppler ultrasonography in subclavian steal syndrome（SSS）.Methods The sonographic appearance and the hemodynamic data of carotid, extracranial and intracranial vertebral, subclavian, innominate, basilar and posterior cerebral arteries were displayed with color Doppler ultrasonography.Results The main causes of SSS were atherosclerosis and takayasu＇s arteritis. There was significant difference in age composition, sex distribution and predilection site between them. The blood supply of the ipsilateral artery in most of the SSS patients was compensated by that of contralateral vertebral artery. Conclusion Most of the SSS patients could be diagnosed by color Doppler ultrasonography.
