Should not change clinical aortic management; leaves open whether dynamic low wall shear stress predicts branch vessel disease in humans.
Computational simulation of the thoracic aorta reveals complex, highly dynamic flow patterns, with low wall shear stress and pressure along the proximal walls of the arch branches.
Laı́n et al. (2017) studied Thoracic aorta blood flow dynamics. Unsteady blood flow dynamics simulation was evaluated on Velocity contours, secondary flow, pressure and wall shear stress distributions. Simulation of unsteady blood flow in a thoracic aorta model demonstrated highly dynamic wall shear stress that was lowest along the proximal walls of the arch branches.
