Cerebrospinal fluid is produced by the choroid plexus in the ventricular system. It fills the ventricles and subarachnoid space, and surrounds the brain and spinal cord. It has the functions of protecting the brain and spinal cord from external mechanical damage and regulating intracranial pressure. The purpose of cerebrospinal fluid puncture is to check whether there is intracranial hemorrhage, whether there are irritation symptoms in the meninges, brain metastases of leukemia, and certain neurological symptoms.

Generally, patients are required to lie on their side on a flat bed and bend their body as much as possible to unfold the lumbar vertebrae.
