Aneurysm rupture rates are often associated with factors such as size, location, and patient specific risks such as age and health. However, the actual physiological causes of the pathogenesis, enlargement, and rupture are unclear. Many studies have shown aneurysm formation to be mechanically mediated. Hemodynamic forces such as wall shear stress (WSS), pressure, and flow patterns have been examined as causes for aneurysm development and eventual rupture [1]. Geometric factors such as the aneurysm size, shape, and aspect ratio may also be important in predicting rupture [2,3].
