Ventriculoperitoneal Shunt Surgery: Before Your Surgery

What is ventriculoperitoneal shunt surgery?

Ventriculoperitoneal (VP) shunt surgery drains extra fluid out of the brain. The extra fluid moves into the belly and is absorbed by the body. This helps control the pressure in the brain so the brain can work as it should.

Some health problems can cause swelling and pressure in the brain. These include brain tumours and hydrocephalus, which is extra fluid in the brain.

The surgery is done in two parts. First, the doctor drills a small hole in your skull. A thin tube is then placed in the brain's fluid-filled part. Then the doctor threads a thin tube from a cut in your belly to your chest and neck. The two tubes are then connected with a valve. This allows the fluid to drain into the belly.

You will be asleep during this surgery. It usually takes 1 to 2 hours. After the surgery, you will probably stay in the hospital for 2 to 7 days and need to take at least a week off from work. But how long you take off from work depends on the type of work you do and how you feel.

You can do all of your normal activities with the shunt in place. You will have a lump on your head where the valve is. But it may not show after your hair grows back.

You probably will have your VP shunt for life. After several years, you may need to replace it. You may also need to replace it if it stops working well.
