Partial steal has been regarded as a classic ultrasound appearance of subclavian steal syndrome. We report a case with the vertebral artery origin stenosis and intact subclavian artery, which showed the similar partial steal ultrasound features. The following computerized tomography angiography confirmed the stenosis. Therefore, when an alternating flow in the vertebral artery is detected, the investigation of its origin must be performed besides the ipsilateral subclavian artery.
部分盗血一直被认为是锁骨下窃血综合征的经典超声表现。我们报告了一例椎动脉起始段狭窄而锁骨下动脉完整的病例，其表现出相似的部分盗血超声特征。随后的计算机断层血管造影证实了狭窄的存在。因此，当检测到椎动脉出现交替血流时，除了对同侧锁骨下动脉进行检查外，还必须对椎动脉的起源进行调查。
