AB Introduction: Abdominal aortic aneurysm (AAA) is defined as a localized, progressive andpermanent dilation of the aortic wall. Usually are thought to be the end results of irreversiblepathological remodelling of the arterial connective tissue, which causes changes, over time, inAAA geometry, in the constitutive formulation an in the failure criterion. Simple geometricparameters, those obtained directly from the computed tomography CT, can define the AAAfrom a geometrical point of view. It is well documented that aneurysm shape, defined by meansof appropriate relations between simple parameters which are known as GeometricBioDeterminants (GBDs) [1], has strong influence on flow patterns and consequently on wallstress distribution (peak values and locations). Therefore, it has been recognized that the AAAmorphology has a significant influence in its rupture potential. Aim of this study was tocharacterize the influence of the main geometric parameters of the AAA (simple and GBDs) inthe hemodynamic stresses (Wall Shear Stress-WSS and Hemodynamic Pressure-HP) acting on intimal layer
