Aortic Dissection Animation
- An aortic dissection occurs when a tear develops on the inner layer of the aorta. The pressure of the blood pumping through the aorta causes the blood
to surge through the tear and into the middle layer of the aorta, creating a false lumen for the blood.
- Sometimes there is a second tear through which the blood re-enters
the true lumen, but if the false lumen ruptures through the outside aortic wall, aortic dissection can be fatal.
