Аннотация

In this study we considered the effect of formation of cerebral bypass for the real clinical case. Three configurations of vessels of the circle of Willis for the real patient was constructed in the pre-operative, post-operative and the alternative (virtual-without bypass formation) treatment cases. All calculations were carried out in the commercial software ANSYS CFX 17.2. It is shown that after installation of the bypass the stagnation zone in patient's vessel was formed with the consequent thrombus formation that required an urgent re-operation. The changes of hemodynamic parameters (blood flow velocity, WSS and viscous dissipation energy values) before and after operation as well as after alternative treatment were analysed. For the first time, a quantitative difference in hemodynamic characteristics between cases of the real and virtual (alternative) methods of the operation was shown.
