Numerical study on hemodynamic in an s-type arterial end-to-side anastomosis with taylor patch

In order to clarify the influence of Taylor patch on the flow field in a new (S-type) arterial end-to-side anastomosis, a numerical investigation was carried out in terms of the flow patterns, wall shear stresses, and wall shear stresses gradients. The numerical results showed that the Taylor patch had an great effect on the flow field at the distal anastomosis. At the distal anastomosis, more smooth distributions of flow patterns were obtained, and the second flow and the wall shear stress gradients decreased almost 34.48% and 52.22%, respectively, to improve the haemodynamics, while at the artery bottom the wall shear stress was reduced about 30.33% to promote atherosclerosis. Therefore, it can not be concluded that the Taylor patch has superior treatment in S-type bypass graft by only considering haemodynamic factors. Moreover, a lot of animal and clinical experiments are needed to be carried out with numerical study.
