WebIt is most commonly a normal variant. The aorta starts at the hearts left ventricle, arches upwards towards the neck, then curves back downward, extending into the abdomen. Gross anatomy Normally, the aorta ascends in the superior mediastinum to the level of the sternal notch before arching posteriorly and descending in the left hemithorax. There may be additional branches that arise directly from the arch: thyroidea ima artery, usually between the brachiocephalic and left common carotid, left vertebral artery, usually between the left common carotid and the left subclavian arteries, rarely the right subclavian and right common carotid arise independently, ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Treasure Island (FL): StatPearls Publishing; 2021 Jan-. In order from proximal to distal the branches are: brachiocephalic trunk or artery (innominate artery) which goes on to divide into the right subclavian and right common carotid arteries, the aortic arch can be divided by the brachiocephalic trunk into "proximal" and "distal" portions 3, just beyond the last branch, the aortic isthmus represents a minor narrowing at the site of the ligamentum arteriosum, which runs between the undersurface of the aortic arch and the terminal pulmonary trunk,this ligament represents the obliterated foetal ductus arteriosusand due to this attachment, this represents the site of the majority of thoracic aortic injuries when the body undergoes significant deceleration.
