Hemodynamics Analysis of Several Stent Treatments of a Patient Specific Anterior Communicating Artery Aneurysm

CFD predictions of the flow in cerebral aneurysms can help to analyze the mechanisms of growth and rupture and the degree of stress for a given flow conditions and to compare and to propose different stenting treatments. In this work we simulated the flow in a model of cerebral aneurysms of a real patient in six different conditions. One case corresponds to the flow conditions in the aneurysm without treatment and the other five cases correspond to different options or strategies of treatment with open cell stents (OCS) and closed cell stents (CCS) to hold the coil. The aneurysm is located in the anterior communicating artery (AComA). The effect of the treatment on the hemodynamics is quantified and reported.
