经颅多普勒与彩色多普勒超声对锁骨下动脉盗血综合征的诊断价值

目的:探讨经颅多普勒(TCD)与彩色多普勒超声对锁骨下动脉盗血综合征(SSS)的诊断价值。方法:应用彩色多普勒超声检测32例SSS患者的椎动脉颅外段、颈动脉、锁骨下动脉(SubA)、无名动脉的彩色血流形态,内-中膜厚度及狭窄程度;TCD检测椎动脉颅内段与基底动脉血流方向及频谱的改变。结果:32例中SubA中度狭窄11例,重度狭窄12例,闭塞9例。TCD检查Ⅰ期盗血11例(34%);Ⅱ期盗血11例(34%);Ⅲ期盗血10例(32%)。结论:彩色多普勒超声与TCD联合应用,通过对SubA及无名动脉的内-中膜厚度、狭窄程度及椎-基底动脉频谱形态的测量,有利于对SSS病因及程度的诊断。

Diagnostic value of TCD and color Doppler ultrasound in subclavian artery steal syndrome

Objective： To investigate the diagnostic value of subclavian artery steal syndrome （SSS） using transcranial Doppler （TCD） combined with color Doppler ultrasound. Methods： Applied color Doppler ultrasound to detect the degree of stenosis and color flow from 32 cases of patients with SSS in extracranial vertebral artery, carotid artery, subclavian artery and innominate artery of the tunica intima. Applied TCD to detect the blood flow direction and the spectrum changes in intracranial vertebral artery and basilar artery. Results： In 32 cases of subclavian artery, 11 cases were moderate stenosis, 12 cases were severe stenosis, 9 cases were occlusion. TCD examination stage Ⅰ steal 11 cases （34%）; Ⅱ period steal 11 cases （34%）; Ⅲ period steal 10 cases （32 %）. Conclusion： Application of color Doppler ultrasound and TCD is good for the diagnosis of etiology and extent of the subclavian steal syndrome by detecting the tunica intima of subclavian artery and innominate artery , the degree of stenosis and the spectrum shape measurement of vertebral-basilar artery.
