Left Vertebral Artery, Aortic Arch, Anatomy, Anatomical VariationAbstract
The aortic arch has three branches. The brachiocephalic trunk, the first and largest branch, ascends toward the right side of the trachea, dividing into the left common carotid and left subclavian arteries. The second and third branches, respectively, are the right common carotid and right subclavian arteries, with their respective branches, and may frequently present anatomical variations. One of the branching patterns observed in the aortic arch is a direct origin of the left vertebral artery between the left common carotid and left subclavian arteries, which is of great clinical importance. This case report describes an anatomical variation of the left vertebral artery, which originated from the aortic arch between the left common carotid and subclavian arteries. This was observed during dissection of the anatomical specimen in the Human Anatomy Laboratory of the School of Health Sciences of the Amazonas State University.
