Abstract


Although the vertebral artery (VA) is a type of artery with a lot of variations, its origin from the common carotid artery (CCA) is one of the rarities that deserves to be presented.Microdissection of injected arteries in the thorax and neck of human fetuses under the operating microscope was used and documented in the workbook and photos. The origin of the left VA from ipsilateral CCA, and its entry into the transverse foramen of the fourth cervical vertebra (C IV), associated with the normal vascular arrangement of branches of the aortic arch were the main features of this case. Simultaneously, the right VA of normal (subclavian) origin entered the C V transverse foramen. A present case of the left VA−CCA variant is the only one discovered in human fetuses, respectively, in total it is the tenth human case in the literature. However, the future findings could show whether the right aortic arch and the carotid stenosis discovered in half of known adult cases can be possible causal and/or consequent abnormalities of the left VA−CCA variant.
