The difference between a thoracic aortic aneurysm and a pseudo aneurysm.

The difference between a thoracic aortic aneurysm and a pseudoaneurysm. Do you know much about that? So I guess the question is, a true aneurysm of a blood vessel involves all three layers and blood vessels have three layers which are the intima, the media and the adventitia. aortic aneurysms will grow from the lumen out. If the aneurysm doesn't contain all three layers then it is referred to as a pseudoaneurysm. A broad range of conditions can cause a pseudoaneurysm, for example a road traffic accident which causes a disruption of the throes of the aorta will cause a kind of bubble of blood around the aorta and that's referred to as a pseudoaneurysm. an infection can sometimes cause damage to the side of the aortic wall and then there will be a contained rupture that will be a pseudorheanism. So I think that there are different ways that a pseudorheanism can present in the throat aorta and in the same way that it can present in any artery.
