Question: the new classification or type of aortic arch? I want to ask the classification of aortic arch(morphyology or angiography).Maybe three types in my memory.PS:not Coarctation or dissection. Thanks! I want to ask the classification of aortic arch(morphyology or angiography). In my memory, Maybe three types and have something about the main branch of aortic arch(carotid artery,subclavian artery,brachiocephalic artery).PS:not Coarctation or dissection. Thanks! In my memory, The latest concept has three types and has something to do with the main branch of aortic arch (carotid artery,subclavian artery,brachiocephalic artery). But the only reference I can find in the internet was a paper in 1994 and the aortic arch was divided into two types. Type â… : the innominate artery, left common carotid artery and left subclavian artery originate from the highest site of aortic arch. Type â…¡: the innominate artery, left common carotid artery and left subclavian artery originate from the site before the highest of aortic arch. Thank you very much for your answer! I wait for it urgently! Thanks! In my memory, The latest concept has three types and has something to do with the main branch of aortic arch (carotid artery,subclavian artery,brachiocephalic artery).

Answer: For descriptive purposes, aorta is divided into three main parts:-(1) the ascending aorta, (2) the arch of aorta, and (3) the descending aorta. The descending aorta is subdivided into (a) the descending thoracic aorta and (b) the abdominal aorta.
