How it Works

Rupture of the Abdominal Aortic Aneurysm (AAA) is the 15th leading cause of death in the United States and is one of the most fatal surgical emergencies, with an overall mortality rate of 90%, according to the National Library of Medicine. Clinical repair is needed before an AAA rupture. 

Iowa Technology Institute scientists are using a collaboration of numerical modeling and simulation to investigate how rupture of AAA initiates and propagates. The research attempts to predict the rupture location and direction so that the surgery can be conducted to prevent rupture.
