Surgery: What to Expect – Implanting a Ventriculoperitoneal (VP) Shunt

Need Caption

Detail - Ventriculoperitoneal (VP) shunt placement

Your neurosurgeon will walk you through the surgical process for shunt implantation, which includes important steps before, during, and after the procedure.

Before the Procedure

In order to help prevent infection, some of the hair on your head may need to be shaved. The medical team will wash your head and body with special soap. 

Your neurosurgeon will make sure you understand the procedure, and answer any questions you may have.

During the Procedure

The neurosurgery team performs the surgery in sterile conditions in theatre under general anaesthesia. The operation usually takes less than an hour. It generally involves the following steps:

  1. A small incision will be made in the scalp. A small hole will then be made in the skull.
  2. A tiny opening will be made in the protective coverings of the brain. These openings accommodate the catheter placement in the lateral ventricle.
  3. The neurosurgeon will make two or three small incisions to place the shunt valve (usually above or behind the ear).
  4. The catheter will be tunneled under the skin.
  5. The end of the catheter will be carefully placed in the appropriate receiving cavity (usually the abdomen).
  6. Following the operation, small sterile bandages will be applied to each incision.

After the Procedure

Immediately after surgery, you will be taken to the recovery room. You will stay there for close observation for an hour or so and then be taken to their ward. Most patients leave the hospital within 2 to 7 days, depending on their progress.

Although this is the usual procedure when a shunt is placed, each individual may have a slightly different experience based upon their neurosurgeon, hospital, and their particular medical needs.
