Abstract
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.
