摘　　要：目的探讨椎动脉多普勒频谱形态改变与锁骨下动脉(Sub-A)近段病变程度之间的关系。方法 119例确诊为Sub-A近段狭窄/闭塞患者,分析其椎动脉频谱形态与Sub-A狭窄程度之间的关系,并进行分组比较;同时观察颈总动脉、颈内动脉、椎动脉及对侧Sub A狭窄情况,分析其对窃血的影响。结果 (1)Sub-A轻度狭窄组的窃血发生比例明显低于中度以上狭窄组(P<0.0.001);Sub-A中度狭窄组的显性窃血比例明显低于重度以上狭窄组(P<0.001)。(2)单纯一侧Sub-A狭窄患者的窃血发生比例明显高于合并颈总动脉、颈内动脉、椎动脉和对侧Sub-A狭窄者(P<0.05)。结论 Sub-A近端狭窄是决定椎动脉窃血频谱的主要因素,头颈部其他动脉病变对该频谱也有影响。Objective To study the correlation of Vertebral artery waveform alteration and the degree of subclavian artery（Sub-A） stenosis. Methods 119 patients with Sub-A proximal stenosis/occlusion were reviewed, the relationship of VA steal waveform and Sub-A stenosis was analyzed, data of different groups were compared; Stenosis of carotid artery, vertebral artery and contralateral subclavian artery were also studied, and their influence on the Vertebral artery steal waveform was analysed. Results （1） The group with mild Sub-A stenosis has a lower ratio of Vertebral artery steal spectrum than the group with Sub-A stenosis above mild （P〈0. 001） ; The group with moderate Sub- A stenosis has a significantly lower ratio of dominant steal spectrum than the group with Sub-A stenosis above moderate（P〈0. 001）. （2） Patient group with simply unlateral Sub-A stenosis has a higher ratio of Vertebral artery steal spectrum than the group with complicated carotid artery, Vertebral artery or contralateral Sub-A stenosis （P〈0. 05）. Conclusions Vertebral artery steal Doppler spectrum was mainly decided by proximal Sub-A stenosis, and was affected by other extracranial cerebral arteries.
