Atherosclerosis: Some theories about collagen, ischemic wall etc, but most are in atherosclerotic vessels in abdomen or elsewhere.
Aneurysms can happen in any blood vessel, but AAA is the most common.
Some rare infections , congenital, traumatic.

Several theories: Most common belief is that aneurysms develop due to some inherent weakness in the artery's muscular layer due to an imbalance of collagen metabolism or genetic collagen abnormalities. The only independent risk of aneurysm growth is high blood pressure and smoking.
