Hemodynamic analysis of cerebral saccular aneurysms across sizes and cardiac cycle stages via computational technique

In the present study, the variations in hemodynamic parameters within distinct cerebral saccular aneurysms during different stages of the cardiac cycle are comprehensively investigated. By comparing these parameters, the research aims to elucidate potential differences in hemodynamic behavior across aneurysm types and cardiac cycle phases. A computational technique is applied for the evaluation of the blood flow inside cerebral aneurysms. The primary attention is to investigate the change of main hemodynamic factors related to the haemorrhage of the aneurysm in six different patients with different sac sizes. The Casson Model is used for the estimation of blood viscosity in our simulations. The findings offer insights into the hemodynamic intricacies of cerebral saccular aneurysms, shedding light on how these variations might influence the pathology and potential treatment strategies for such conditions. Our finding shows that the wall shear stress is high near the ostium region and increasing the sac volume decreases the critical high Wall shear stress region near the neck area.
