It is a form of aneurysm Kendall. The aorta has three layers and what happens is that a tear in one layers opens up and literally rips down the aorta to some point where it stops. It is generally fatal because it will stop the blood supply to the brachial or renal arteries or the dissection continues into the femoral artery OR actually extends into the heart itself. The survival rate is very low for obvious reasons and any dissection will eventually cause death. The only real scenario for someone to survive the initial dissection is if it happens in a way as to properly continue to feed the brachial and renal arteries and stops below the aortic arch and above the femoral artery.
