Background: Anomalies associated with the vertebral arteries are relatively rare. The vertebral arteries arise from the first part of the Subclavian artery and pass through the transverse foramina of C6 through C1.
Case presentation: However, in this article, we describe a unique variation in the anatomical orientation of the right vertebral artery during a routine cadaveric neck dissection where the right vertebral artery gives an oblique branch from the extradural segment (C2) forming a fenestrated Vertebral artery.
Conclusion: Despite the lack of established clinical significance, multiple co-morbid vascular malformations are yet associated with the Vertebral artery fenestration with a possibility of iatrogenic injuries if not taking into cognisance.
