An enlarged aorta is defined by its location on the blood vessel, the size of the bubble and what shape it takes. It is possible for the aorta to become enlarged in all directions or simply develop a small bulge on one side of the blood vessel.
The aorta is the main blood vessel that carries blood to the rest of the body. In patients with Marfan Syndrome, the walls of the aorta are weaker than normal. This can cause the aorta to enlarge and stretch. An abnormal bulge in the wall of the aorta (an aneurysm) may develop. The inner and outer layers of the aortic wall can also separate (a dissection).
