<P> Severely raised ICP, if caused by a unilateral space - occupying lesion (e.g. a hematoma) can result in midline shift, a dangerous sequela in which the brain moves toward one side as the result of massive swelling in a cerebral hemisphere . Midline shift can compress the ventricles and lead to hydrocephalus . </P> <P> The most definitive way of measuring the intracranial pressure is with transducers placed within the brain . A catheter can be surgically inserted into one of the brain's lateral ventricles and can be used to drain CSF (cerebrospinal fluid) in order to decrease ICP's . This type of drain is known as an extraventricular drain (EVD). This is rarely required outside brain injury and brain surgery settings . </P> <P> In situations when only small amounts of CSF are to be drained to reduce ICP's (e.g. in IIH), drainage of CSF via lumbar puncture can be used as a treatment . Non-invasive measurement of intracranial pressure is being studied . </P> <P> The treatment for IH depends on the cause . In addition to management of the underlying causes, major considerations in acute treatment of increased ICP relates to the management of stroke and cerebral trauma . </P>
