The Author reports 2 cases presenting vertebro-basilar insufficiency. In the first one, surgery was interrupted due to the hyperflexed positioning of the head which caused cardiorespiratory disorders and increased vertebro-basilar insufficiency. In the second case the patient, placed in a different position, survived the operation. The postoperative angiographic control confirmed the disobstruction of the vertebral flow at the level of the malformation. Electromyography detected the presence of innervation of tongue muscles.
作者报告了2例出现椎基底动脉供血不足的病例。在第一例中，由于头部过度屈曲的体位导致心肺功能障碍并加重了椎基底动脉供血不足，手术被迫中断。在第二例中，患者处于不同体位，手术成功。术后血管造影检查证实畸形部位椎动脉血流恢复通畅。肌电图检测到舌肌存在神经支配。
