Cerebral aneurysms are abnormal bulges of an artery found at branches and bifurcations of the flow domain. Their rupture is of primary concern to neuro-trauma care providers. Aneurysm management options include clipping, coiling, stenting etc. Determination of rupture status as well as rupture risk would be of immense clinical value in patient management. Such a risk is often determined based on population cohort studies on the clinical data of patients and morphological features derived from the radiological inputs etc. Shape based information is often described with the aid of parameters such as Dome height, Size ratio, Ellipticity index, undulation index, maximum size, aspect ratio, neck width etc. Unfortunately, not all these parameters have been found to be useful in assessing either rupture status or rupture risk. In view of this lacune, present study proposes to develop a morphological parameter that can holistically represent a wide spectrum of aneurysm morphologies. The proposed study would assess the influence of this parameter by performing detailed hemodynamic simulations to derive various hemodynamic indicators such as Wall shear stress, oscillatory shear index and relative residence time etc. This study proposes to benchmark the utility of the novel parameter using both CFD and FSI based patient-specific simulations to aid the clinicians in the decision making process.
