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.
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.
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.
与椎动脉相关的异常相对罕见。椎动脉起自锁骨下动脉第一段，穿过C6至C1的横突孔。
然而，在本文中，我们描述了在一次常规尸体颈部解剖过程中右椎动脉解剖方向的一种独特变异，即右椎动脉从硬膜外段（C2）发出一条斜支，形成一条有窗孔的椎动脉。
尽管尚未明确其临床意义，但椎动脉窗孔仍与多种合并存在的血管畸形相关，如果未加以认识，可能会导致医源性损伤。
