Key result
A downstream peripheral vascular impedance model using computational fluid dynamics successfully assessed atherosclerosis hemodynamics and transient flow division in patient-specific carotid bifurcations.
A novel CFD model incorporating downstream peripheral vascular impedance allows for hemodynamic assessment of carotid atherosclerosis when outlet boundary conditions are unavailable.

May support virtual intervention planning in carotid disease; leaves open prospective clinical validation before adoption.
Dong et al. (2012) studied Carotid bifurcation atherosclerosis. Downstream peripheral vascular impedance CFD model was evaluated on Hemodynamic parameters (time-averaged wall shear stress, oscillatory shear index, relative residence time) and flow division. A downstream peripheral vascular impedance model using computational fluid dynamics successfully assessed atherosclerosis hemodynamics and transient flow division in patient-specific carotid bifurcations.
