Key result
Severe carotid stenosis disrupts hemodynamics, increasing maximum blood flow velocity ~5-fold versus healthy arteries.
Why the study?
Cardiovascular disease driven by atherosclerosis carries a high risk of transient ischemic stroke, and irregular blood flow at the carotid bifurcation and bulb may promote plaque progression.
How does 80% stenosis in the carotid bulb region alter haemodynamic and structural parameters compared to a healthy carotid artery?
Population
Patient-specific carotid artery models
Comparison
Healthy vs stenosed carotid artery with 80% blockage in the carotid bulb region
Design
Two-way fluid-structure interaction analysis

Alerts to elevated wall stress in severe carotid stenosis models; leaves open applicability to human plaque rupture risk.
How does 80% stenosis in the carotid bulb region alter haemodynamic and structural parameters compared to a healthy carotid artery?
Computational fluid-structure interaction analysis demonstrates that 80% carotid stenosis profoundly alters bio-fluid dynamics, increasing wall stress six-fold compared to healthy arteries.
Abhilash et al. (2024) studied Carotid artery stenosis (n=2). 80% carotid artery stenosis vs. Healthy carotid artery was evaluated on Hemodynamic and structural parameters (velocity, pressure, von Mises stress). An 80% carotid artery stenosis significantly disrupted hemodynamics, increasing maximum blood flow velocity fivefold to 3.6 m/s and elevating maximum von Mises stress to 227 kPa compared to 37.7 kPa in a healthy artery.
