Summary: | Recent aneurysm studies have focused on the correlation between different parameters and rupture
risk; however, there have been conflicting findings. Computational fluid dynamics (CFD) allows for
better visualization but idealized aneurysm models may neglect important variables such as aneurysm
shape and blood flow conditions. In this paper, one case of an aneurysm was studied with CFD using
a non-Newtonian Power Law Model to investigate the correlation between wall shear stress and blood
cells distribution. Results show that velocity of blood flow decreased as it entered the aneurysm and
the neck of the aneurysm experienced a greater magnitude of wall shear stress than the remainder of
the cerebral artery. Besides, the blood cells generally begin at low velocities and increase after the first
curve of the artery. Findings and further studies with larger cases of patients will improve treatment
and prevention of aneurysm ruptures.
