Key result
Simulated 45% stenosis indicates higher thrombosis risk than aneurysms due to increased viscous stress.
Why the study?
The danger of rupture for severe cases of stenosis and aneurysms requires investigation through numerical computation forecasting hemodynamic rupture risks.
Computational modeling indicates that for an equivalent 45% depth, arterial stenosis creates more severe hemodynamic disruptions and higher thrombosis risk than an aneurysm.

The danger of rupture for severe cases of stenosis and aneurysms is extensively studied by healthcare professionals and researchers. Numerical researchers have likewise played a role in forecasting this rupture. This study offers a numerical computation of a time-dependent three-dimensional arterial flow of Newtonian fluid, examining the influence of stenosis and aneurysm on atherosclerosis-related hemodynamics. The pulsatile blood flow simulation has been executed with the software code of COMSOL Multiphysics using a finite element approach. Results indicate that the stenotic model creates hemodynamic conditions associated with a higher risk of thrombosis compared to the aneurysm model. A higher viscous stress is found in the stenotic model compared to that of the aneurysm model. Higher magnitudes of velocity and pressure are estimated for the stenotic model. It can be concluded that for the same height of stenosis and aneurysm, the stenosis model poses a severe risk to humans.

Md. Jashim Uddin (2025) studied Atherosclerosis (Stenosis and Aneurysm). Stenosis model (45% depth) vs. Aneurysm model (45% depth) was evaluated on Hemodynamic risk parameters (TAWSS, OSI, RRT, velocity, pressure). A computational simulation showed that a 45% depth stenotic model creates hemodynamic conditions with higher viscous stress and pressure, indicating a higher thrombosis risk than an aneurysm model.
