Warrants caution against uniform wall shear stress assumptions; extends site-specific hemodynamic insights in aortic bifurcation models.
In an in vitro model of a human aortic bifurcation, intimal thickness generally correlated positively with maximum instantaneous wall shear stress, though this relationship was reversed at the flow divider tip.
Hayashi et al. (1996) studied Hemodynamics and intimal thickness (n=1). Wall shear stress was evaluated on Correlation between wall shear stress and intimal thickness. Wall shear stress showed a positive correlation with intimal thickness overall, but a negative correlation at the circumference of the flow divider tip in a human aortic bifurcation model.
