Does an additional re-entry tear affect flow, pressure and wall shear stress distribution in a 3D aorta model of Stanford Type B aortic dissection?
Computational fluid dynamics simulation suggests that an additional re-entry tear in Stanford Type B aortic dissection decreases false lumen pressure but increases local wall shear stress, which may promote distal tear extension.
Naim et al. (2013) studied this question.
