As in the arteries, the walls of veins have three layers, or coats: an inner layer, or tunica intima; a middle layer, or tunica media; and an outer layer, or tunica adventitia. If a rupture occurs in the inside lining of the aorta, the tunica intima, it can lead to blood being forced between the tunica intima and the tunica media (the inside and middle layers of the aorta).
