Computational simulation of blood flow in a DeBakey type I aortic dissection

摘要: The main purpose of this study is to examine how flow field in aortic dissection affected by its geometry and condition. Two models DeBakey type I dissection, which involves the entire aorta, were analyzed. Patient-specific geometries reconstructed, based on Computed tomography (CT) scan images, order obtain 3D finite element meshes. Computational fluid dynamics (CFD), uses numeric methods algorithms for simulation blood solving Navier-Stokes equations computational meshes, enhances understanding disease progression. For that purpose, major dynamic parameters indicators progression, such as velocity field, pressure shear stress, computed results showed higher velocities ascending inlet outlet tears iliac arteries, case both models. distribution high zones while stress low aneurysm part, In summary, presented can be extended a larger patient group longitudinal with goal determine potential value CFD simulations prediction aneurysmal growth rupture.
