Abstract
To investigate the difference of the hemodynamics of aneurismal model in the circle of Willis virtually treated with closed cell and open cell stent, two kinds of stents were constructed. One is Enterprise stent (Closed-cell), and the other is Neuroform stent (open-cell). Five treatment strategies based on the combination of two kinds of stents were used. The computational fluid dynamics of these five different treatment strategies was calculated and the corresponding hemodynamic characteristics of aneurismal model were analyzed. In particular, the effects of different structural stents and their combinations on the blood flow characteristics (streamline, wall shear stress) of the aneurysm cavity were discussed.
