Earlier diagnosis of life-threatening abdominal aortic aneurysm (AAA) rupture may be on the horizon thanks to research by the University of Manitoba's David Kuhn. AAA rupture is a catastrophic event that results in a death rate of over 90%. Kuhn, a Professor in the Department of Mechanical and Manufacturing Engineering, is using direct numerical simulation (DNS) to study the physiological blood flow in AAA.

Previous studies have shown that blood flow hemodynamics play a significant role in both the biological and mechanical factors that predispose AAA formation and rupture. Using realistic patient-derived 3D models to simulate and assess pulsatile flow, Kuhn aims to better understand the role of hemodynamics on the growth of AAA.

WestGrid and Compute Canada systems are critical to this simulation and assessment of these compute-intensive models. In addition to contributing to new insights into the relationships between hemodynamics and AAA rupture, Kuhn's research also has the potential to assist surgeons in identifying AAA that are at a high risk of rupture.
