Several things: About 5% of men over the age of 65 have abdominal aortic aneurysms. Risk factors include: increasing age, male sex, family history of aneurysm (may increase your risk 4-fold), hypertension, and history of smoking. Dissecting aneurysms can be caused by localized damage to to the artery from hypertension or trauma (deceleration or sheering-type injury) or catheter injury from an angiogram.

Many: "causes" are associated problems that are thought to be the reasons. Remember, though, that association is not necessarily causation. That said, more important is what to do about presence of aneurysm. Since there is weakness in the "pipe", this needs to be evaluated whether treatment is necessary, urgent or elective, or not at all. Seeing a vascular surgeon for an opinion is needed.

Known risk factors: Certain aneurysms are caused by genetic predispositions that is caused by such conditions as marfan's syndrome. Otherwise the usual cardiovascular risk factors such as hypertension, diabetes, hypercholesterolemia and smoking.

Unknown : There are factors thought to be associated with the development of an aortic aneurysm such as genetic problems with an enzyme called elastase, other types of collagen disorders, and possibly hypertension. It is difficult, if not impossible, to detect the specific cause for most individual patients.
