Computational Fluid Analysis of Stented Cerebral Aneurysm in Smokers

Abstract

Recent studies say that 6.5 million people have unruptured cerebral aneurysms. Modern treatment for unruptured cerebral aneurysms uses newly devised flow diverters like pCONus, pulse rider, eCLIPs, etc.. Among these, eCLIPs has been the subject for many studies and has been proved to be more effective than others. CFD analysis is used to investigate blood flow post the placement of flow diverters. There is no detailed CFD study for smokers with aneurysms post endovascular treatment with flow diverters. In our study, we considered both smokers and non-smokers and analysed blood flow post-treatment with eCLIP using CFD. The properties of blood vessels and blood flow vary for smokers due to the presence of chemicals like nicotine. Here the blood vessel with eCLIP is modelled and visualised using Blender software. The blood vessel with and without aneurysm is modelled for various conditions using COMSOL software for CFD analysis. The velocity and pressure variation are analysed for different areas in the blood vessel.
