Patient specific fluid-structure interaction study of cerebral aneurysm

The recent developments in computational methods can be useful in observing the detailed haemodynamics in cerebral aneurysms for understanding not only their formation and rupture but also for clinical evaluation and treatment. However, important hemodynamic quantities are difficult to measure in vivo. The present study deals with a patient specific case of having a large aneurysm on left side internal carotid bifurcation (ICA) bifurcation and right side is normal. The simulation of FSI results provides a comparison of flow behaviour between normal and aneurysm models. It demonstrates the significance of flow analysis in understanding the haemodynamics at crucial sites and agrees well with the available literature and clinical observation.
