摘　　要：目的探讨锁骨下动脉窃血综合征患者的椎动脉频谱类型与锁骨下动脉或无名动脉狭窄程度的关系。方法回顾性分析了经数字减影血管造影(DSA)证实的41例锁骨下动脉窃血综合征(SSS)患者的椎动脉多普勒超声表现,将锁骨下动脉或无名动脉的狭窄程度与椎动脉频谱类型进行对照分析。结果 41例SSS患者中,DSA诊断的轻度狭窄8例,中度狭窄16例,重度狭窄或闭塞17例,超声检查椎动脉频谱类型中窃血前期表现者11例,部分窃血表现者18例,完全窃血表现者12例,所有椎动脉窃血程度与同侧锁骨下动脉或无名动脉狭窄程度相关(r s=0.472,P<0.05)。结论 SSS患者椎动脉的频谱表现与锁骨下动脉或无名动脉的狭窄程度密切相关,但对于多发狭窄的患者应综合分析,避免低估狭窄程度。Objective To examine the relationship between the spectral categories of vertebral artery retrograde blood flow and subclavian artery stenosis in patients with subcleavian steal syndrome （SSS）. Methods We analyzed the spectral characteristics of vertebral artery in 41 patients with SSS confirmed by, digital subtraction angiography （DSA）, which entailed comparison on the spectral categories of vertebral artery retrograde blood flow by stratification of the degree of subclavian artery or innominate artery stenosis. Results Of 41 patients with SSS, 8 had mild, 16 moderate and 17 severe stenosis of subclavian artery or innominate artery. There were 11, 18 and 12 patients with premature, partial and complete manifestations of SSS, as evidenced by Doppler spectra. The degree of retrograde flow in vertebral artery was positively correlated with that of stenosis of ipsilateral subeclavian or innominate artery （rs= 0.472, P〈0.05）. Conclusion The degree of in subclavian or innominate artery stenosis is closely associated with the spectral categories of vertebral artery retrograde blood flow in Doppler ultrasonography in patients with SSS. A com- prehensive algorithm should be applied for patients with multiple artery stenosis, thus reducing the risks of underesti- mation.
