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.
Introduction. An abdominal aortic aneurysm (AAA) is a swelling (aneurysm) of the aorta â the main blood vessel that leads away from the heart, down through the abdomen to the rest of the body. The abdominal aorta is the largest blood vessel in the body and is usually around 2cm wide â roughly the width of a garden hose.However, it can swell to over 5.5cm â what doctors class as a large AAA. Large aneurysms are rare, but can be very serious.n aneurysm is a bulge in a blood vessel caused by a weakness in the blood vessel wall. As blood passes through the weakened blood vessel, the blood pressure causes it to bulge outwards.
