Analysis of hemodynamics of intracranial saccular aneurysms.
The aim of this paper is to present the impact of artery curvature and neck size of aneurysms on growth rate and effectiveness of treatment of aneurysms. The dynamics of three-dimensional (3D) lateral aneurysms on arteries of different curvature were analysed using Comsol Femlab software. The simulations were performed for both steady as pulsatile flows. The effect of artery curvature and neck size of aneurysms on parameters such as flow velocity, aneurysm wall shear stress, size of the area of blood reaction (impact area) during the cardiac cycle were evaluated as well as relations between the size of impact area and artery curvature or neck size of aneurysms were provided.
