Vertebral artery arises from the upper surface of the first part of subclavian artery on both sides. The morphological variations of the vertebral artery are of immense importance in surgery, angiography and all non-invasive procedures. During the routine dissection of a male cadaver aged about 65 years, we observed a variation in the branching of arch of aorta. The arch of aorta gave off four branches-brachiocephalic trunk, left common carotid artery (CCA), left vertebral artery (LVA) and left subclavian artery. LVA was arising between left CCA and left subclavian artery.The knowledge of variations in the vertebral artery is of great clinical interest to the neurosurgeon and radiologist for diagnostic investigation and surgical procedures of the neck.
