Hydrocephalus is a condition where extra fluid collects inside the brain and puts pressure on it. This pressure can cause headaches, memory loss, balance problems, and vision issues. It can affect babies, children, and adults. If untreated, hydrocephalus may cause serious complications. 

The most common hydrocephalus treatment is VP shunt surgery (ventriculoperitoneal shunt placement). In this surgery, a small tube drains the extra fluid safely from the brain into the abdomen.

This blog will explain the causes of hydrocephalus, describe how VP shunt surgery is performed, outline possible risks, discuss recovery, and provide information on life after surgery, so that you know exactly what to expect.

Understanding Hydrocephalus and Its Causes

The word hydrocephalus means “water on the brain.” Instead of water, the extra fluid is cerebrospinal fluid (CSF), which normally cushions the brain and spinal cord. CSF is continuously produced and absorbed, but in hydrocephalus, either too much is made or the normal drainage system is blocked.

Common Causes of Hydrocephalus

• Congenital factors – birth defects such as spina bifida
• Infections – meningitis or encephalitis can scar pathways and block CSF flow
• Brain tumours – tumours can physically block fluid circulation
• Head injury or bleeding – trauma may damage or block drainage channels
• Normal Pressure Hydrocephalus (NPH) – in older adults, fluid buildup may mimic dementia, causing memory loss, walking problems, and bladder issues

If untreated, hydrocephalus leads to increased intracranial pressure (ICP), which can cause headaches, vomiting, blurred vision, imbalance, and, in severe cases, brain damage.

“Many patients don’t realise they have hydrocephalus until symptoms worsen,” says Dr. Vikas Gupta. “That’s why early diagnosis and VP shunt surgery are so important; it can save brain function and improve quality of life.” 

What Is VP Shunt Surgery?

A VP shunt (ventriculoperitoneal shunt) is a small medical device used to divert excess CSF from the brain’s ventricles to the abdominal cavity. The body then reabsorbs the fluid naturally.

The system includes:

• A ventricular catheter – placed in the brain’s ventricle
• A valve – to regulate the flow of fluid, preventing too much or too little drainage
• A distal catheter – under the skin to the abdomen, where the fluid drains

When Is VP Shunt Surgery Needed?

Ventriculoperitoneal shunt placement is typically recommended when:

• Hydrocephalus symptoms are worsening
• Imaging (MRI/CT scans) shows enlarged ventricles
• Increased intracranial pressure is affecting daily function
• Medications or less invasive treatments aren’t effective

It’s considered the gold-standard hydrocephalus treatment, especially for patients who need long-term management.

The parents of a patient shared, “My son was diagnosed with congenital hydrocephalus as a baby. He had frequent vomiting and was always irritable. When we contacted Dr. Vikas Gupta, he explained VP shunt surgery in detail, which gave us confidence. The surgery went smoothly, and today Aarav goes to school like any other child.”

Another patient from the UAE shared, “I had been experiencing constant headaches and difficulty walking for months before I was diagnosed with Normal Pressure Hydrocephalus. Travelling to India for VP shunt surgery was a difficult decision, but Dr. Vikas Gupta explained every step, which reassured me. The surgery changed my life, my headaches improved, I could walk without help, and I finally felt like myself again.”

The VP Shunt Surgery Procedure

Although the idea of brain surgery sounds overwhelming, VP shunt surgery is a standard neurosurgical procedure performed routinely worldwide.

Step-by-Step: How It’s Done

1. Anesthesia – The patient is given general anesthesia to remain asleep and pain-free
2. Incisions – A small opening is made in the scalp and skull to access the brain’s ventricle. Another small incision is made in the abdomen
3. Catheter placement – A thin tube (catheter) is inserted into one of the brain’s ventricles
4. Valve attachment – The catheter connects to a valve that regulates CSF flow
5. Tunneling – A long tube runs under the skin from the head, behind the ear, down the neck, and into the abdominal cavity
6. Connection – The ventricular catheter and the abdominal catheter are connected via the valve system
7. Closure – Incisions are closed with stitches, and a bandage is applied

The entire surgery usually takes 1–2 hours. Most patients stay in the hospital for several days for monitoring.

Dr. Vikas Gupta adds, “The goal of VP shunt surgery is simple: relieve pressure on the brain and restore normal function. With modern techniques, most patients recover well and quickly.” 

Risks and Complications of VP Shunt Surgery

Like all surgeries, a ventriculoperitoneal shunt procedure carries some risks. However, it’s important to note that complications can often be managed successfully with timely medical attention.

Possible Risks Include:

• Infection: May need antibiotics or shunt change
• Blockage: Can bring back hydrocephalus symptoms
• Over/Under-drainage: May cause headaches or dizziness
• Abdominal problems: Pain or swelling where fluid drains

The good news is that modern shunt systems are highly reliable, and most patients do well after surgery with proper care.

VP Shunt Recovery: What to Expect

Immediate Recovery in Hospital

• Stay: 3–7 days depending on age and health
• Monitoring: Doctors check for infection, healing, and shunt function
• Pain relief: Mild incision pain is common but manageable

At-Home Recovery

• Patients may experience weakness or fatigue for a few weeks
• Gradual return to daily activities is advised
• Heavy lifting and strenuous activity should be avoided initially
• Children often return to school in 2–3 weeks; adults may return to work depending on job type

Long-Term Recovery Process

• VP shunt recovery means adjusting to life with the device
• Symptoms such as headaches, walking difficulties, or memory issues often improve
• Some patients need rehabilitation therapies (physical, speech, or occupational) for full recovery

Follow-Up Appointments

Regular follow-up appointments are essential after VP shunt surgery. During these visits:

• Imaging tests (CT/MRI) may be ordered
• Programmable shunts may be adjusted
• Any new symptoms are reviewed

Patients are also taught to watch for warning signs: fever, redness at the incision, worsening headaches, vomiting, or confusion. These may signal infection or malfunction and need urgent care.

Living with a VP Shunt

Most people live normal, active lives after ventriculoperitoneal shunt placement.

• Some may need shunt revisions during their lifetime, but modern systems last longer
• For older adults with Normal Pressure Hydrocephalus (NPH), surgery can dramatically improve memory, walking ability, and bladder control
• For children, early shunt placement supports normal growth and learning

Living with a VP shunt is about balance: regular check-ups, awareness of warning signs, and a positive outlook. With this, patients can lead full lives,” says Dr. Vikas Gupta.

Final Thoughts

VP shunt surgery has transformed the treatment of hydrocephalus. Draining excess CSF relieves increased intracranial pressure (ICP) and prevents brain damage.

While risks such as infection or malfunction exist, most patients benefit significantly from this procedure. The recovery process may take weeks, but with proper wound care, monitoring, and regular follow-up appointments, patients typically experience significant improvements in their quality of life.

If you or your loved one is facing hydrocephalus, remember that with timely diagnosis and expert neurosurgical care, living with a VP shunt is not only possible but can mean a safe return to healthy, independent living.

FAQs About VP Shunt Surgery

1. Will I feel the VP shunt inside my body?

You may feel a small bump under the scalp where the valve is placed, but over time, you may adjust quickly and not notice it daily.

2. Can hydrocephalus return even after VP shunt surgery?

The shunt manages fluid buildup, but regular follow-ups are essential since complications or blockages can cause symptoms to return.

3. What happens if the shunt gets infected?

Shunt infections may cause fever, redness at incision sites, abdominal pain, or worsening neurological symptoms. Treatment often involves antibiotics or shunt replacement.

4. How long does a VP shunt usually last?

VP shunts can last many years, but they may require revision if they become blocked, infected, or if the patient outgrows the device.

5. Is VP shunt surgery different for infants, children, and adults?

The surgical steps are similar, but valve types, catheter lengths, and follow-up care are tailored according to the patient’s age and growth needs.
