Key result
3D computational fluid dynamics analysis demonstrated that the highest wall shear stress (4.37 Pa) corresponded to the most severely stenotic segment during systole, while ulceration appeared downstream.

Resolution limits hinder CFD for severe carotid stenosis; leaves open higher-resolution validation in neurointervention.
Purpose: Computational fluid dynamics (CFD) applications for atherosclerotic carotid stenosis have not been widely used due to limited resolution in the severely stenotic lumen as well as small flow dimension in the stenotic channel.

Oh et al. (2010) conducted a case report in Severe carotid bulb stenosis with ulceration (n=1). Computational Fluid Dynamics (CFD) modeling was evaluated on Hemodynamic characteristics (wall shear stress, flow velocity, wall pressure). 3D computational fluid dynamics analysis demonstrated that the highest wall shear stress (4.37 Pa) corresponded to the most severely stenotic segment during systole, while ulceration appeared downstream.
