Aortic Aneurysms: It is not entirely clear exactly what causes aortic aneurysms, but we know of a few risk factors, probably the most significant of which is smoking. Other risk factors include atherosclerosis and high blood pressure. There is also a hereditary component, so these can run in families. There are also genetic syndromes such as Marfan's or ehlers-danlos which are associated. See a vascular surgeon.

Occur not caused: Congenital familial rare Marfan etc atherosclerosis and wall deterioration over time with dilation some after dissection some after trauma- more pseudoaneurysms from that.

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.

Abdominal (AAA)?: We are not quite sure what actually causes an AAA to form in some people. The leading thought is that the aneurysm may be caused by inflammation in the aorta, which may cause its wall to weaken or break down. Most believe that this inflammation can be associated with atherosclerosis (also called hardening of the arteries) or risk factors for atherosclerosis, such as high blood pressure and smoking.

Aortic aneurysms: Aortic aneurysms are commonly associated with high blood pressure. They also have a familial ncidence probably due to collagen structure. Some genetic syndromes commonly are associated with aortic aneurysms. Some inflammatory diseases can involve the aortic wall and cause aneurysms. Atherosclerotic disease can also be an association.

What could cause an aortic aneurysm to burst?

Ruptured aneurysm: An abdominal aneurysm can rupture for many reasons. Most common is size. As the aneurysm enlarges the wall gets weaker. We know that aneurysms over 5 cm have a higher rupture rate and those should be operated on electively. Other factors making rupture more likely would be uncontrolled high blood pressure and infection in the wall of aneiurysm.

Lot of things: Atherosclerosis (hardening of arteries), aging, infection (syphilis for one), traujma, some congenital problems such as marfan's or ehlers-danlos where there is inherited weakness in the artery wall, and inflamation. Hypertension can cause a "dissecting aneruysm" ( a tear in the aorta).
