Stent deployment in aneurysmatic cerebral vessels: Assessment and quantification of the differences between Fast Virtual Stenting and Finite Element Analysis

Abstract : To assess the efficacy of stenting procedure in the treatment of cerebral aneurysms, a tool predicting accurately and with fast execution time the stent released configuration could be very useful. The aim of this work is to propose a first validation of the Fast Virtual Stenting method by comparing its results with the ones achieved with Finite Element Analysis. A series of parametric models has been set varying the geometries of the stent, the vessel and the aneurysmal neck, and the differences between the two methods have been evaluated comparing the released configurations in corresponding models. Results show a quite fine match between the two methodologies, accompanied by a significant reduction in the computational costs gained with FVS. In this way, this method seems to be a promising tool to help clinicians choosing the best treatment option.
