Hydrocephalus is a condition where there is a build-up of cerebrospinal fluid (CSF) within the normal fluid-filled chambers within the brain (ventricles).
These operations are performed under general anaesthetic and normally take 60-90 minutes.
Lumbar puncture (LP) is a procedure involving the use of a needle inserted into the lower part of the spinal canal.
A meningioma doesn’t always require immediate treatment. However some meningioma tumours can grow and start to affect the brain.
A subarachnoid haemorrhage (SAH) occurs when bleeding takes place into the subarachnoid space, the layer surrounding the brain which contains cerebrospinal fluid (CSF).
This is bleeding into the subarachnoid space - a layer of membrane that lies beneath the skull protecting the brain.
