Abstract:

The core of the thesis work has been dedicated to the study of intracranial aneurysms using fluid dynamics simulations. To attain high-fidelity representations of the bio-mechanical interactions, a computational framework has been designed, including new additions to the field of simulation techniques, validation cases and meshing routines. The framework has then been adapted to the special environment of brain arteries considering medical and anatomical aspects. In addition, a virtual flow-diverter deployment has been developed to permit the analysis of complex cases involving the post-treatment remodelling. Lastly, the framework is exploited to simulate the fluid dynamics in several patient cases, suffering rare and complex forms of aneurysms that are still poorly understood.
