During the dissection of the cervico-thoracic region of a 25-year-old female cadaver, 2 main trunks originating from the convex aspect of the aortic arch with additional variations were encountered. The brachiocephalic trunk and left common carotid artery arose from the first trunk. The other trunk was formed by the left subclavian artery and left vertebral artery. Additionally, the external carotid artery and its branches coursed in front of the hypoglossal nerve on the right side and on the left side, and the left vertebral artery ran through the transverse foramina of the C7 vertebrae.
