We report the case of a patient who suffered iatrogenic vertebral artery injury (VAI) during a cervical spine posterior fixation procedure. The patient suffered massive bleeding and hemorrhagic shock at the time of screws placement in C1 lateral mass and C2 pedicle. The postoperative MRI and CT angiography showed a pseudoaneurysm 7.0 cm in diameter in the cervical spine. The iatrogenic VAI during posterior screw fixation is extremely rare. But, it can cause catastrophic consequences. We discuss the causes for the iatrogenic VAI and review the preventative measures and suitable management to avoid iatrogenic complications.
我们报告了一例在颈椎后路固定手术中发生医源性椎动脉损伤（VAI）的患者病例。该患者在C1侧块和C2椎弓根置入螺钉时发生大量出血和失血性休克。术后MRI和CT血管造影显示颈椎有一个直径7.0厘米的假性动脉瘤。后路螺钉固定过程中的医源性VAI极为罕见。但是，它可能会导致灾难性后果。我们讨论了医源性VAI的原因，并回顾了预防措施和适当的处理方法以避免医源性并发症。
