Key result
Ultrasound-based CFD demonstrates feasibility for personalized risk mapping of disturbed flow in severe stenosis.
Why the study?
Carotid atherosclerosis increases stroke risk, but treatment decisions rely primarily on stenosis degree, which poorly reflects individual vulnerability.
Observational (n=8)
An ultrasound-driven computational fluid dynamics framework is feasible for personalized risk mapping of carotid hemodynamics, highlighting helicity as a potential diagnostic marker.
Does not yet support routine carotid risk stratification with ultrasound CFD; leaves open whether helicity enhances stenosis-based stroke prediction.
Atherosclerosis in the carotid arteries increases stroke risk, yet current treatment decisions rely mainly on stenosis degree, which poorly reflects individual vulnerability. We present an ultrasound-based computational fluid dynamics (CFD) framework for patient-specific hemodynamic assessment. Using tracked 2D ultrasound and automated segmentation, we reconstructed carotid geometries for five healthy subjects and three patients with severe stenoses. CFD simulations quantified TAWSS, OSI, RRT, and helicity, visualized through risk maps. Healthy arteries showed localized risk near bifurcations, whereas stenosed geometries exhibited extensive disturbed flow and altered helicity patterns. This approach demonstrates the feasibility of ultrasound-driven CFD for personalized risk mapping and highlights helicity's potential as a diagnostic marker.

Piek et al. (2026) conducted an observational in Carotid artery stenosis (n=8). Ultrasound-based computational fluid dynamics (CFD) was evaluated on Hemodynamic assessment (TAWSS, OSI, RRT, and helicity). Ultrasound-based computational fluid dynamics demonstrated feasibility for personalized risk mapping, revealing extensive disturbed flow and altered helicity in 3 patients with severe stenoses.
