A left vertebral artery arising from the aortic arch: a cadaveric study

ABSTRACT

Variations in the major arteries and their branches of the thoracic region have been well described with variations of the aortic arch, pulmonary trunk, common carotid arteries and vertebral arteries being among the most common in the thoracic region. During routine dissection of the thoracic and neck regions, the left vertebral artery in a 58-year-old female cadaver was found to arise from the arch of the aorta between the left common carotid and the left subclavian arteries. The left vertebral artery was traced along its course and was observed to enter the transverse foramen of the fifth cervical vertebral body. With such variation, the findings can influence predisposition to diseases, symptomatology, clinical examination, investigation and patient management, including operative surgery
