title: Computer modelling of CSF flow in the subarachnoid space.
abstract: Computer modelling has been undertaken to determine the resistance to flow in the subarachnoid space (SAS) and to investigate its contribution to the total pressure drop. A Computational Fluid Dynamics model has been used to determine the pressure drop as a function of both the flow rate and the permeability of the subarachnoid space. The conclusion is that the SAS contributes about 1-5% of the total CSF flow resistance. However, scarring of the arachnoid fibres could increase the flow resistance considerably.
