Modal analysis of blood flows in saccular aneurysms

What've we done?

High-fidelity Computational Fluid Dynamics simulations were performed and systematically coarsened to generate 72 cases with varying spatial and temporal resolutions. The Hankel DMD method was then used to identify dominant flow modes and instabilities within the aneurysm sac.

What've we found?

The results demonstrate that DMD analysis reveals unique patient-specific 3D flow structures independent of aneurysm geometry, and the energy pseudo-spectrum effectively captures flow dynamics even at low resolutions comparable to clinical imaging (CT or MRI). Aneurysmal hemodynamics can be categorized into 'laminarized flows' and 'transient dynamics' based on cumulative energy curves, offering a new quantitative tool that could significantly improve clinical rupture risk assessment.
