Key result
A computational fluid dynamic analysis of the aortic arch showed higher spatial shear stress at the inner wall and major vessel origins, with highly skewed velocity patterns on transversal sections.
Complex fluid dynamics in the aortic arch, characterized by high shear stress at the inner wall and branch origins, may contribute to endothelial responses and inflammatory events.

May link arch hemodynamics to endothelial activation; leaves open in vivo clinical relevance.
Gaudio et al. (2006) studied Aortic arch hemodynamics. Non-Newtonian fluid model vs. Newtonian fluid model was evaluated on Spatial and temporal distribution of shear stress and velocity patterns. A computational fluid dynamic analysis of the aortic arch showed higher spatial shear stress at the inner wall and major vessel origins, with highly skewed velocity patterns on transversal sections.
