Abdominal Aortic Aneurysm (AAA) is a dilation of the aorta of at least 50% increase in diameter, or an aortic diameter over 3 cm. If left untreated, an AAA will increase in size until rupture of the aortic wall causes a life threatening hemorrhage [1]. The current criterion for a repair procedure is a maximum diameter of the AAA of at least 5.5 cm. However, the diameter is not adequate for some small AAAs that rupture early [2]. Therefore, multiple studies have focused on and published data on patient-specific wall stress analyses. Fillinger et al. (2002) found higher peak wall stresses in ruptured AAAs than in electively repaired AAAs [3].
