Abstract
The present article investigates geometrical features of an aneurysm, particularly the sac centreline length (SCL), in determining the hemodynamic environment within the aneurysm for evaluation of the haemorrhage risk. Indeed, understanding how these geometric characteristics influence blood flow patterns is essential for assessing rupture risk and optimizing treatment strategies. Computational fluid dynamic is used to perform computational modelling of the blood hemodynamic in ACA cases. Wall shear stress (WSS), OSI and pressure over sac surface are investigated and compared for selected saccular aneurysm to evaluate risk of aneurysm rupture when sac centreline length is varied. Comparison of the results show that the inverse relationship between sac centerline length and these key hemodynamic parameters (OSI, velocity, WSS) underscores the importance of geometrical factors in assessing aneurysm rupture risk. Longer sac centerline lengths appear to be associated with more stable flow dynamics and reduced mechanical stress, while shorter sac lengths correlate with more disturbed and high-stress conditions.
