Abstract
Abstract A three-dimensional model of the aqueduct of Sylvius (AS) is used to simulate the behavior of pressure and velocity of cerebrospinal fluid (CSF). Magnetic resonance imaging (MRI) of the brain, obtained from databases were used for the reconstruction of the model. Boundary conditions from different authors were use in order to prove the proposed model. Computational Fluid Dynamics (CFD) tools predicted that the maximal velocity occurs at the narrowest point of the AS. On the other hand, the inclusion of the third and fourth ventricles in the models is not significant on both pressure drop and velocity profiles. This work allows to analize variations in pressure and velocity in the AS with different boundary conditions.
