Definition

Shunt – ventriculoperitoneal; VP shunt; Shunt revision

Ventriculoperitoneal shunting is surgery to treat excess cerebrospinal fluid (CSF) in the brain ( hydrocephalus ).

Description

This procedure is done in the operating room under general anesthesia. It takes about 1 1/2 hours.

The procedure is done as follows:

  • An area of hair on the head is shaved. This may be behind the ear or on the top or back of the head.
  • The surgeon makes a U-shape cut behind the ear. Another small surgical cut is made in the belly.
  • A small hole is drilled in the skull. A thin tube called a catheter is passed into a ventricle of the brain. This can be done with or without a computer as a guide. It can also be done with an endoscope that allows the surgeon to see inside the ventricle.
  • Another catheter is placed under the skin behind the ear. It is sent down the neck and chest, and usually into the belly area. Sometimes, it stops at the chest area. The doctor may make a small cut in the neck to help position it.
  • A valve (fluid pump) is placed underneath the skin behind the ear. The valve is connected to both catheters. When extra pressure builds up around the brain, the valve opens, and excess fluid drains through the catheter into the belly or chest area. This helps lower intracranial pressure.
  • The person is taken to a recovery area and then moved to a hospital room.

Why the Procedure Is Performed

This surgery is done when there is too much cerebrospinal fluid (CSF) in the brain and spinal cord. This is called hydrocephalus. It causes higher than normal pressure on the brain. It can cause brain damage.

Children may be born with hydrocephalus. It can occur with other birth defects of the spinal column or brain. Hydrocephalus can also occur in older adults.

Shunt surgery should be done as soon as hydrocephalus is diagnosed.

Risks

Risks of anesthesia and surgery in general are:

  • Reactions to medicines or breathing problems
  • Bleeding , blood clots, or infection

Risks of ventriculoperitoneal shunt placement are:

  • Blood clot or bleeding in the brain
  • Brain swelling
  • Hole in the intestines (bowel perforation), which can occur later after surgery
  • Leakage of CSF fluid under the skin
  • Infection of the shunt, brain, or in the abdomen
  • Damage to brain tissue
  • Seizures

The shunt may stop working. If this happens, fluid will begin to build up in the brain again. As a child grows, the shunt may need to be repositioned.

Before the Procedure

If the procedure is not an emergency (it is planned surgery):

  • Tell the health care provider what medicines, supplements, vitamins, or herbs the person takes.
  • Take any medicine the provider said to take with a small sip of water.

Ask the provider about limiting eating and drinking before the surgery.

Follow any other instructions about preparing at home. This may include bathing with a special soap.

After the Procedure

The person may need to lie flat for 24 hours the first time a shunt is placed.

How long the hospital stay is depends on the reason the shunt is needed. The health care team will closely monitor the person. IV fluids, antibiotics, and pain medicines will be given if needed.

Follow the provider’s instructions about how to take care of the shunt at home. This may include taking medicine to prevent infection of the shunt.

Outlook (Prognosis)

Shunt placement is usually successful in reducing pressure in the brain. But if hydrocephalus is related to other conditions, such as spina bifida, brain tumor, meningitis, encephalitis, or hemorrhage, these conditions could affect the prognosis. How severe hydrocephalus is before surgery also affects the outcome.

 

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Rest, drink safe water, and observe symptoms carefully.
  • Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.
  • Seek medical care quickly if symptoms are severe, worsening, or unusual for the patient.

OTC medicine safety

  • For mild pain or fever, ask a registered pharmacist or doctor before using common over-the-counter pain/fever medicines.
  • Do not combine multiple pain medicines without advice, especially if you have kidney disease, liver disease, stomach ulcer, asthma, pregnancy, or take blood thinners.
  • Do not give adult medicines to children unless a qualified clinician advises it.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Severe symptoms, confusion, fainting, breathing difficulty, chest pain, severe dehydration, or sudden weakness need urgent medical care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider
Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
