Vortex formation dominates aneurysm flow models; leaves open its role in rupture risk without clinical validation.
Mathematical modeling of arterial aneurysms reveals vortex formation and high pressure gradients at the downstream end of the expansion.
S.Ø. Wille (1981) studied Arterial aneurysm. Mathematical simulation using Navier-Stokes equations was evaluated on Pressure and flow patterns. Mathematical simulation of pulsatile flow in an arterial aneurysm demonstrated vortex formation during most of the cardiac cycle, nearly constant pressure, and high downstream pressure gradients.
