In brief: Medial necrosis
Cystic medial necrosis induced by arteriosclerotic obliteration of the vasa vasorum of the aorta is the most common cause.

The cause of aortic aneurysm development is NOT entirely understood. There are many biochemical changes, and some inflammatory reactions that are thought to be associated with development. There is a higher risk of aneurysms with first degree family members having aneurysms. Aneurysm risk also increases with smoking, age, and male gender.

The three greatest risk factors for AAAs are being MALE, > 65 yrs, and having ever smoked.

Dr Oliver Aalami makes a very good point about smoking in addition to age and genes

In brief: .? AAA
They are a bulge in the wall of the aorta (your main artery running through your abdomin and ultimately supplying the blood to your legs) from a weakness.
They can be thought of like a bulge in your garden hose. The exact cause is still under investigation.

The vast majority of AAA are caused by atherosclerotic disease. There are some rare other causes. Reducing the risks of atherosclerosis will reduce the risks of AAA
