Causes
The exact cause of an abdominal aortic aneurysm has not been identified. However, the following are possible risk factors:
- Atherosclerosis: This is due to damage to the vessel as a result of substances accumulating on the lining.
- Blood vessel disease: This disease can cause inflammation which may make the vessel more prone to an aneurysm.
- Trauma: Trauma to the abdominal area may affect the vessel and make an aneurysm more likely.
- Tobacco use: Tobacco may weaken and damage the walls of the aorta, making them more likely to bulge.
- High blood pressure: High blood pressure can weaken the aorta walls increasing the risk of a bulge forming.
- Aorta infection: While rare, it is possible for an infection to increase the risk of an aneurysm.
- Heredity: In some cases, experts believe that abdominal aortic aneurysms may run in families.
