Variations of major arterial vessels are of clinical significance. The vertebral artery(VA) normally arises from the subclavian artery. The present report describes an anomalous origin of the left vertebral artery(LVA) from the aortic arch between the origin of left subclavian and left common carotid artery. The artery was crossed superficially form medial to lateral side by left sympathetic chain. The left and right VA entered the foramen on the transverse process of fifth cervical vertebrae. Though the anamolous origin of VA is known .its origin and entry through the foramen transversarium and its relation with sympathetic trunk are of importance during clinical and vascular procedures in the head and neck region like carotid stents,VA stents and intracranial interventions.
