Causes of Abdominal Aortic Aneurysm
An AAA develops because of an underlying weakening in the wall of your aorta. This impairment is caused by a combination of inherited and environmental causes. In general, it’s unclear why precisely they form.
For instance, smoking results in the loss of structural proteins in the wall of your aorta. It loses strength as a result. Another factor that might weaken the wall of your aorta is plaque accumulation, or atherosclerosis. In the layers of the arterial wall, plaque development and expansion over time can result in inflammation and cell death. The disintegration of aortic wall building blocks makes the aorta weaker and more susceptible to aberrant enlargement.
