A tear in the aorta's inner walls lets blood leak into the middle layer of the wall, causing the layers to separate. This is called dissection or tear. If this happens where the aorta rises out of the heart (a Type A dissection), it is life threatening and requires emergency surgery.

This damage to the inner wall of the aorta is known as an aortic dissection (ADD), in which a tear in the wall creates two channels. The blood continues to travel in one channel but is stagnant in the other, causing the rupture to balloon and push on other branches of the aorta, constricting their blood flow.
