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.

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.
