The vertebral artery (VA) has an intimate relationship with the bones of the craniovertebral junction. An exact understanding of the VA anatomy in general and in the specific surgical case in particular is absolutely necessary in order to avoid intraoperative vascular injury. The course of the VA on the inferior aspect of the superior facet of the C2 vertebra makes it susceptible to damage during transarticular and interarticular fixation with the screw insertion in the adjacent lateral mass. The consequences of the intraoperative VA injury will depend on the patency of other arteries supplying the brain. In case of this complication, quick decision-making is essential to avoid excessive blood loss and to preserve adequate cerebral blood flow.
椎动脉（VA）与颅颈交界部的骨骼关系密切。为了避免术中血管损伤，了解 VA 的解剖结构，尤其是特定手术病例中的 VA 解剖结构，是绝对必要的。VA 在 C2 椎体上关节突的下方走行，使其在经关节突和关节内固定以及相邻侧块螺钉插入时容易受到损伤。术中 VA 损伤的后果将取决于供应大脑的其他动脉的通畅情况。在发生这种并发症的情况下，快速决策至关重要，以避免过度失血和保持足够的脑血流。
