Cerebrospinal Pulsation Hydrodynamics in A 2d Simulation of Brain Ventricles

In this article, dynamics of the cerebrospinal fluid (csf) was studied, using computational fluid dynamics.using mri images of two special cases, a 2-dimensional model of the ventricular system was made. csfvelocity and pressure distribution in ventricular system have high importance since the flow pattern of thisliquid has an important effect on intracranial pressure, i.e., icp, which has a key role in treatment of patientssuffering from brain trauma. the pulsatile nature of csf production, which is a result of arterial bloodpressure in choroid plexuses, is considered for the first time. finite element analysis of ventricular area withcfd analyzer software was processed using adina 8.2. pressure distribution in different conditions of csfproduction, i.e., constant input flow rate and pulsatile input flow rate, were compared. comparison betweenthe simulation results and reported experimental data depicted that modeling csf with pulsatile productionnature is more realistic.
