Post-traumatic hydrocephalus: influence of craniectomy on the CSF circulation

Shapiroet al 2 attempted to offer an interesting but conceptually difficult hypothesis that the time constant (resistance to CSF outflowxcompliance of cerebrospinal space) of cerebrospinal system hydrodynamics has a tendency to remain constant. [...]a mechanistic increase in compliance after craniec...

Description
Summary:Shapiroet al 2 attempted to offer an interesting but conceptually difficult hypothesis that the time constant (resistance to CSF outflowxcompliance of cerebrospinal space) of cerebrospinal system hydrodynamics has a tendency to remain constant. [...]a mechanistic increase in compliance after craniectomy tends to be followed by a decrease in the resistance to CSF outflow. Overnight ICP monitoring or CSF infusion study should be performed after cranioplasty, when CSF circulatory reserve decreases dramatically. [...]a prolonged period without a bone flap may encourage ventricular dilatation.
