Abstract

Computer simulation is carried out for unsteady hemodynamics in a cerebral aneurysm of a blood vessel. Using the data of a real patient obtained in medical examination and during surgery, we reconstruct the 3D geometry of the anomaly, calculate hydrodynamic parameters of blood flow (flow velocity, streamline distribution, pressure, shear stress on walls, energy flux) and the deformation and stresses of the vessel walls. The calculations were performed for the following three cases: in the presence of an aneurysm, immediately after stent deployment changing the geometry of the vessel, and one year after the surgery. It is shown what changes of hydrodynamic and mechanical quantities characterize a successful surgery.
