What is the term used for drawing fluid from a hydrocephalus head?

The term used for drawing fluid from a hydrocephalic head is "ventriculostomy." This procedure involves creating an opening in the ventricles of the brain to allow for the drainage of excess cerebrospinal fluid (CSF) and alleviate pressure. Another common procedure is "lumbar puncture," which can also be performed to remove CSF from the spinal canal.
