BACKGROUND: Endovascular intervention using a stent is a mainstream treatment for @entity438 . To assess the effect of intervention strategies on @entity439 hemodynamics, we have developed a fast virtual stenting (FVS) technique to simulate stent deployment in @entity1 -specific @entity439 . However, quantitative validation of the FVS against experimental data has not been fully addressed. In this study, we performed in vitro analysis of a @entity1 -specific model to illustrate the realism and usability of this novel FVS technique. METHODS: We selected a @entity1 -specific @entity439 and reproduced it in a manufactured realistic aneurismal phantom. Three numerical simulation models of the @entity439 with an Enterprise stent were constructed. Three models were constructed to obtain the stented @entity439 : a physical phantom scanned by micro-CT, fast virtual stenting technique and finite element method. The flow in the three models was simulated using a computational fluid dynamics software package, and the hemodynamics parameters for the three models were calculated and analyzed. RESULTS: The computational hemodynamics in the @entity1 -specific @entity439 of the three models resembled the very well. A qualitative comparison revealed high similarity in the wall shear stress, streamline, and velocity plane among the three different methods. Quantitative comparisons revealed that the difference ratios of the hemodynamic parameters were less than 10%, with the difference ratios for area average of wall shear stress in the @entity439 being very low. CONCLUSIONS: In conclusion, the results of the computational hemodynamics indicate that FVS is suitable for evaluation of the hemodynamic factors that affect treatment outcomes.
