PURPOSE
To present case of vertebral artery duplication surrounding the posterior arch of atlas.
METHODS
The vertebral artery variation was encountered during dissection of specimen from the body of a 62-year-old man.
RESULTS
The vertebral artery formed a circle located extraduraly, surrounding the posterior arch of atlas vertebra. Topography and morphometry of the finding is described. Embryology and clinical significance based on literature review are discussed.
CONCLUSIONS
Precise diagnostic imaging is necessary before surgical interventions at the level of cranio-spinal junction in order to avoid conflict with rare vascular variations.
目的
报告一例椎动脉在寰椎后弓周围重复走行的病例。
方法
在对一名62岁男性尸体标本进行解剖时发现了椎动脉变异。
结果
椎动脉在硬膜外形成一个环绕寰椎后弓的环。描述了该发现的局部解剖和形态测量情况。基于文献综述讨论了其胚胎学及临床意义。
结论
在颅颈交界区进行手术干预前，需要精确的诊断性影像学检查，以避免与罕见的血管变异发生冲突。
