A ventriculoperitoneal (VP) shunt placement is surgery to insert a draining device from inside the skull to the abdomen. It allows excess fluid to drain from the brain into the abdomen. The fluid can be reabsorbed in the abdomen.
Reasons for Procedure
The interior of the brain has 4 spaces called ventricles. The ventricles hold a fluid that bathes and cushions the brain and spinal cord. Certain health conditions and injuries can cause an excess amount of this fluid, called
hydrocephalus. Excess fluid creates too much pressure and can lead to brain damage.
VP shunt placement is done to treat hydrocephalus. Half of the ventriculoperitoneal shunts that are placed can successfully drain the excess fluid.

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Blockage of the shunt
- Excess bleeding
- Blood clots
- Damage to normal brain tissue
- Adverse reaction to anesthesia
- Soreness in throat
- Nausea and vomiting
- The need for additional surgery
Smoking may increase your risk of complications.
What to Expect
Prior to Procedure
The doctor may do the following:
- Physical exam and medical history
- Blood tests
Talk to your doctor about your medications. You may be asked to stop taking some medications up to 2 weeks before the procedure.
Before the procedure, you should:
- Arrange for a ride home from the hospital.
- Arrange for help at home, as you recover.
- Eat a light meal the night before your surgery. Do not eat or drink anything after midnight unless told otherwise by your doctor.
- Talk to your doctor if you take any medications, herbs, or supplements.
Description of the Procedure
The hair over the area will be shaved. A small incision will be made in the scalp. It may be just past the hairline, on back of the head, or behind the ear. A small hole is then made in the skull. A tube is passed through the hole into a ventricle. A valve is placed on the tube to manage the flow of fluid. A small incision may be made behind the ear to help pass the tube. Another tube is attached to the other side of the valve and is guided under the skin of the skull until it reaches the abdomen. A small incision will also be made in the abdomen to help guide the tube into the correct place in the abdomen. After the tube is in place, the incisions are closed.
Immediately After Procedure
After the operation, you will be taken to the recovery room for observation.
How Long Will It Take?
About 2 hours
How Much Will It Hurt?
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
Average Hospital Stay
This is done in a hospital. The usual length of stay is 2-7 days. If you have any problems, you may need to stay longer.
To help with your recovery at home:
- Avoid pushing, pulling, and lifting anything heavy for 4 weeks.
- Do not participate in sports or exercise until your doctor says it is okay.
- Do not drive for 2 weeks.
- Follow any instructions on caring for the ventriculoperitoneal shunt.
Call Your Doctor
Contact your doctor if your recovery is not progressing as expected or you develop complications such as:
- Evidence of valve blockage as described by your doctor
- Redness, swelling, increasing pain, excessive bleeding, or discharge from the incision site
- Signs of infection, including fever and chills
- Pain that you cannot control with the medications that you were given
- Nausea and vomiting
- Lightheadedness and fainting
- Severe headache
- Changes in vision
- Memory loss
- Difficulty speaking
- Clear fluid draining from the incision site
If you think you have an emergency, call for emergency medical services right away.
