Arterial variations in the branching pattern of arch of aorta are uncommon and may occur as a result of developmental changes in the fusion and absorption of various pharyngeal arch arteries into the aortic sac. The present case report describes a finding in a male cadaver aged between 6065 years about the origin of left vertebral artery directly from the arch of aorta. Such variations should be kept in mind during surgical procedures in the superior mediastinum.
