An aortic aneurysm is a general term for any swelling (dilatation) of the aorta, usually representing an underlying weakness in the wall of the aorta at that location. In general, if the diameter of the aorta increases more than 1.5 times its normal size, the condition is called an aneurysm.

Most intact aortic aneurysms do not produce symptoms. As they enlarge, symptoms such as abdominal pain and back pain may develop. Untreated, aneurysms tend to become progressively larger, although the rate of enlargement is unpredictable for any individual.

Aneurysm is 5 times more common in men than in women.

Although an aneurysm can develop anywhere along the aorta, abdominal aneurysms are more common than thoracic ones. The risk of rupture also depends on the location of the aneurysm.

When detected in time, an aortic aneurysm can usually be repaired with a surgery. The goal of treatment is to prevent aneurysm’s rupture.
