Lumbar-peritoneal shunt
Shunt for hydrocephalus
If you have excessive cerebrospinal fluid (CSF), our expert neurosurgeons can treat you with a lumbar peritoneal shunt
What is hydrocephalus and how can it be treated?
Our neurosurgeons can carry out a lumbar peritoneal shunt to drain the fluid so it doesn't pose a risk.

What happens during surgery? icon plus
A lumbar peritoneal shunt is a small device that aims to relieve pressure on the brain, caused by a build-up of fluid on the brain. The procedure is carried out under general anaesthetic.
Your neurosurgeon will start by making a small incision in your lower back, before inserting a shunt (thin tube) into your spinal canal. The shunt will be joined to a one-way valve and then attached to another tube that travels under the skin to the abdomen. This allows the fluid on your brain to drain into a cavity in your abdomen, where it can reabsorb into your body naturally. -
How to prepare icon plus
Your neurosurgeon will explain your lumbar peritoneal shunt procedure to you and answer any questions you might have. As you'll be having general anaesthetic, they'll let you know how long you should avoid eating and drinking before surgery. You may also be asked to attend a nurse led pre-assessment clinic.
Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you. -
Afterwards icon plus
After your lumbar peritoneal shunt, you'll be transferred to our recovery ward, where you’ll be looked after by a specialist team. Your neurosurgeon will explain your recovery time to you and when you can expect to get back to your usual routine.
