Abstract
  • In this study, we have characterized a series of patient Abdominal Aortic Aneurysms (AAAs) based on their geometric parameters, wall pressure distributions and ages. Abdominal aortic aneurysms (AAAs) are localized aortic dilations that have been estimated to occur in 5 to 7 percent of the U.S. population over age 60. At present, surgical repair is recommended when lesion maximum diameter exceeds 5 cm, regardless of other geometric properties. However, in addition to maximum diameter, many other geometric features, including length, curvature, tortuosity, thrombus distribution and lumenal index can also affect wall stress and thereby alter rupture risk.
