Abstract
Some patients with raised intracranial pressure (ICP) occasionally deteriorate following ventriculography. This deterioration has been considered to be due to the irritating effect of a gas causing overproduction of the cerebrospinal fluid (1), changes in the brain volume due to hyperemia subsequent to the needling of the brain and withdrawal of cerebrospinal fluid (CSF) (2) and mass displacement of the brain (3). Whatever the mechanism, it has been shown that adding volume to the intracranial contents will cause rise in ICP (4,5). As the intracranial volume (ICV) is disturbed during ventriculography, a study was undertaken to determine the magnitude of changes of ICP and to assess the effects on other variables such as heart rate, blood pressure, cortical available oxygen (O2a) and the cerebral blood flow (CBF).
