Hydrocephalus

Hydrocephalus is defined as the abnormal buildup of cerebrospinal fluid in the ventricles of the brain. Cerebrospinal fluid is a colorless saline solution that acts as a “cushion” or buffer for the cortex providing a mechanical protection to the brain. It is produced in the choroid plexus of the ventricles at a rate of 500 ml/day and has a continuous circulation. There are about 150 ml of cerebrospinal fluid in the brain.

The cerebrospinal fluid is basically located in two regions of the nervous systems: in the ventricles where it is produced, and in the subarachnoid space (below the arachnoid meninges) where the cerebrospinal fluid is reabsorbed. There is continuous flow through the ventricular system into the subarachnoid space and finally exiting into the venous ...
