Abstract : We propose a dynamic model of cerebrospinal fluid circulation and intracranial pressure regulation. In this model, we investigate the coupling of biological parameters with a 3D model, to improve the mechanical behavior of the brain in surgical simulators. The model was assessed by comparing the simulated ventricular enlargement evolution with a patient case study of communicating hydrocephalus. In our model, cerebro-spinal fluid production-resorption system is coupled with a 3D representation of the brain parenchyma. We introduce a new bi-phasic model of the brain tissue allowing for fluid exchange between the brain extracellular space and the venous system. The time evolution of ventricular pressure has been recorded on a symptomatic patient after closing the ventricular shunt. A finite element model has been built based on a CT scan of this patient, and quantitative comparisons between measures and simulated data are proposed.
