The geometric characteristics of a saccular aneurysm play a crucial role in its rupturing. This article thoroughly investigates the impact of the sac centerline on aneurysm rupture, with a focus on identifying significant factors related to rupture at different time intervals. The study employs comprehensive computational simulations of six models of the ICA with varying coiling porosities and blood HCTs, using CFD analysis to examine WSS, OSI, pressure, and velocity within the saccular aneurysm for different sac centerlines.

Article Synopsis
  • - The research focuses on how placing a stent affects the internal carotid artery (ICA) aneurysms, specifically looking at changes in the parent vessel and the resulting blood flow dynamics.
  • - Using computational fluid dynamics (CFD) and one-way fluid-solid interaction (FSI), the study examines four ICA aneurysms with different characteristics to visualize blood flow and measure important hemodynamic factors.
  • - The findings indicate that stent-induced deformations can limit blood flow into the aneurysm sac, leading to decreased blood velocity and wall shear stress, which could be more significant in cases with higher oscillatory shear index (OSI) values on the aneurysm wall.

One of the effective treatment options for intracranial aneurysms is stent-assisted coiling. Though, previous works have demonstrated that stent usage would result in the deformation of the local vasculature. The effect of simple stent on the blood hemodynamics is still uncertain.

The formation and progress of cerebral aneurysm is highly associated with hemodynamic factors and blood flow feature. In this study, comprehensive efforts are done to investigate the blood hemodynamic effects on the creation and growth of the Internal Carotid Artery. The computational fluid dynamic method is used for the visualization of the bloodstream inside the aneurysm.
