Lumbar Punctures & Drains

A lumbar puncture is a minimally invasive diagnostic test that involves the removal of a small amount of cerebrospinal fluid (CSF), the fluid that surrounds the brain and spine. The procedure is performed by a small puncture into the region of the spine using x-ray guidance.

A lumbar drain is similar to a lumbar puncture except that a small, soft tube is placed in the lower back to remove CSF. The drain is then carefully monitored to control the flow of CSF for a period of time.
