Possibility of Atherosclerosis in an Arterial Bifurcation Model

Omid Arjmandi-Tash, Seyed Esmail Razavi & Ramin Zanbouri
Introduction: Arterial bifurcations are susceptible locations for formation of atherosclerotic plaques. In the present study, steady blood flow is investigated in a bifurcation model with a non-planar branch. Methods: The influence of different bifurcation angles and non-planar branch is demonstrated on wall shear stress (WSS) distribution using time-dependence three-dimensional Navier–Stokes equations. Results: The WSS values are low in two locations at the top and bottom walls of the mother vessels just before the bifurcation, especially...
