Purpose: The Contour Neurovascular System (CNS) is a novel intrasaccular flow disruptor for the endovascular treatment of wide-necked aneurysms. While more longitudinal studies are needed to fully assess its efficacy, initial study results over the past few years have been promising. However, no studies have yet assessed the CNS’s robustness to deformation over time, and few have assessed its effect on the morphology of intrac...

Purpose Image-based blood flow simulations are increasingly used to investigate the hemodynamics in intracranial aneurysms (IAs). However, a strong variability in segmentation approaches as well as the absence of individualized boundary conditions (BCs) influence the quality of these simulation results leading to imprecision and decreased reliability. This study aims to analyze these influences on relevant hemodynamic paramete...
