Intra-aneurysmal haemodynamics and endovascular device modelling

Technological advances in medical imaging and availability of cerebral angiographies have increased the detection of asymptomatic unruptured aneurysms. Unfortunately, the mechanisms for which the aneurysm wall fails remain unclear and therefore, preventive treatments has grown as a valid option. Since there are several therapies that can be performed, it is not easy to elucidate which one is the most suitable, feasible and reliable for a patient-specific brain aneurysm. To face this challenge, computational modelling arises as a powerful tool to support clinicians, thanks to their predictive capability, speed, relative low costs and full control. This presentation shows how biophysics modelling can be used to model endovascular therapies and to study their impact on intra-aneurysmal haemodynamics. Two examples are provided: First, a virtual coiling technique is presented and used to study its effect on aneurysm local haemodynamics. Secondly, biophysical modelling is used to investigate the impact of arterial flow rate and flow diverter stents on intra-aneurysmal haemodynamics.
