Two cases with vertebro-basilar infarcts associated with severe stenosis of the vertebral artery in its cervical part is reported. Complete thrombosis of the vertebral artery was observed after a short delay in both cases. As the carotid arteries were normal and the controlateral vertebral artery was dominant, an embolic mechanism was suspected. No new event occurred in the following one and three years respectively after the stroke. These two cases demonstrate the possibility of embolism from severe stenosis of the cervical vertebral artery. This mechanism could explain some of the infarcts related to vertebral artery occlusion.
报告了2例伴有椎动脉颈部严重狭窄的椎基底动脉梗死病例。2例均在短时间后观察到椎动脉完全血栓形成。由于颈动脉正常且对侧椎动脉占优势，怀疑存在栓塞机制。中风后分别在接下来的1年和3年未发生新的事件。这2例病例证明了颈椎椎动脉严重狭窄导致栓塞的可能性。这一机制可以解释一些与椎动脉闭塞相关的梗死。
