    There are a number of causes, [3] Aneurysms in patients younger than 40 usually involve the ascending aorta due to a weakening of the aortic wall associated with connective tissue disorders like the Marfan and Ehlers-Danlos syndromes or congenital bicuspid aortic valve. Younger patients may develop aortic aneurysms of the thoracoabdominal aorta ...

[ 6 ] The predictors include if a patient is older than 50, was an unrestrained patient, has hypotension, has a thoracic injury requiring thoracotomy, has a ...

[1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer.

  9. Hemodynamics of the aorta - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics_of_the_Aorta

    As the blood moves into the aortic arch, the area with the highest velocity tends to be on the inner wall. Helical flow within the ascending aorta and aortic arch help to reduce flow stagnation and increase oxygen transport. [4] As the blood moves into the descending aorta, rotations in the flow are less present.
