Numerical AAA flow models generate hypotheses on pulsatile hemodynamics; leaves open validation before any clinical application.
Mechanical forces from pulsatile blood flow, particularly maximum shear stress and pressure at the distal end, may play an important role in the development and growth of abdominal aortic aneurysms.
Viswanath et al. (1997) studied Abdominal aortic aneurysms. Pulsatile blood flow vs. Quasi-steady state was evaluated on Wall shear stress and pressure distribution. Numerical simulation of pulsatile blood flow in abdominal aortic aneurysm models demonstrated that the distal end of the aneurysm is subjected to maximum shear stress and pressure during the cycle.
