Individualized Analysis of the Stent Implantation Performance Based on the Vascular Reconstruction

Abstract

More and more researchers pay attention to the method of using stents treats the intracranial aneurysms through the way of minimally invasive surgery. Due to individual differences between patients and complexity of stenosis lesion, there is not an acknowledged criterion on stenting scheme, which mainly depends on clinicians’ experience. Otherwise, inappropriate stenting scheme may lead to severe complications such as intravascular restenosis after a certain period of time after surgery. By means of simulation to explore this problem is a simple and effective way, but most simulation studies only focus on the design of stent structure and ignore the importance of building a real blood vessel model. The use of idealized vascular model will inevitably affect the simulation accuracy, and it leads to a large difference between the theoretical effect and the actual effect of the stent. Therefore, reconstructing the accurate blood vessel model is the crucial work in this study. In order to research the mechanical properties of stents, the model is constructed by the OpenCASCADE kernel. It provides reference for assessing surgical plan and illuminating biomechanical mechanism of in-stent restenosis. At the same time, it may contribute to novel stent development and optimization design, assist doctor to make better surgical scheme as well as predict surgical results.
