We report three patients who developed delayed (ie, more than a week after the injury) symptoms of vertebrobasilar ischemia following motor vehicle accidents. The patients all had angiographic evidence of vertebral artery dissection and, upon further evaluation, occult fractures of the second cervical vertebra that were not detected by simple cervical spine radiography and required polytomography or CT for diagnosis. Vertebral artery dissection can result from occult cervical spine fractures and may present with delayed symptoms of brain ischemia.
我们报告了三名在机动车事故后出现椎基底动脉缺血延迟症状（即受伤一周后）的患者。所有患者均有椎动脉夹层的血管造影证据，进一步评估发现，第二颈椎隐匿性骨折通过简单的颈椎X线摄影未被检测到，需要断层摄影或CT来诊断。椎动脉夹层可由隐匿性颈椎骨折引起，并可能出现脑缺血的延迟症状。
