Abstract
An aortic aneurysm forms when a part of the thoracic or abdominal aorta weakens and the wall stretches and expands like a balloon. As it balloons outward, the wall of the aorta becomes thinner and weaker. If the wall becomes too thin it may tear open or rupture causing massive internal bleeding which is a life threatening situation. Once an aneurysm reaches a certain size, the risk of rupture exceeds the risk of elective repair. (Inova; 2006).
Anuerysmal disease has been increasing during the past 30 years as population survives to an older age. This increase represents a true growth in disease incidence, rather than an artifact of more widely available screening or increasing volumes of vascular surgery.(Bengtsson H, et aI., 1992).
