Patients with craniovertebral junction anomalies are more likely to undergo craniovertebral junction procedures because of neurologic complications. Vertebral arteries (VAs) are more prone to injury in these cases because of an often anomalous course, with potentially disabling or grave sequel. In our patient with partially occipitalized atlas, CT angiogram revealed that 1 of the VAs passed through the bony canal in the occipitalized and/or fused bone, whereas the VA on unfused side was also unexpectedly anomalous and of C2 segmental type. To the best of our knowledge, such anomaly has never been reported in studies of patients with occipitalized atlas in the literature.
由于神经并发症，颅颈交界区异常的患者更有可能接受颅颈交界区手术。在这些病例中，椎动脉（VA）更容易受到损伤，因为其走行常常异常，可能导致致残或严重的后果。在我们这位部分枕化寰椎的患者中，CT血管造影显示其中一条椎动脉穿过枕化和/或融合骨中的骨性管道，而未融合侧的椎动脉也意外地出现异常，属于C2节段类型。据我们所知，这种异常在文献中关于枕化寰椎患者的研究中从未有过报道。
