The human aortic arch has significant torsion in addition to its large curvature. It has pointed out that the torsion may be related to the development of the thoracic aneurysms. It is also known that the torsion affects the blood flow, which is suspected to be associated with various vascular diseases. In this study, a realistic three-dimensional computational fluid dynamics model of a human aortic arch was constructed based on a set of MR images and the blood flow in the arch was simulated. The results showed that the torsion of the aortic arch led to a complex localized distribution of the wall shear stress.
