This guide will help you get ready for your surgery to have your programmable or nonprogrammable ventriculoperitoneal (VP) shunt placed at Memorial Sloan Kettering (MSK). It will also help you understand what to expect during your recovery.
Read through this guide at least once before your surgery and use it as a reference in the days leading up to your surgery.
Bring this guide with you every time you come to MSK, including the day of your surgery. You and your healthcare team will refer to it throughout your care.Back to top
About Your Surgery
A VP shunt is used to drain extra cerebrospinal fluid (CSF) from your brain. CSF is the fluid that surrounds your brain and spinal cord. It’s made in the ventricles (hollow spaces) inside your brain.
CSF protects your brain and spinal cord by acting as a cushion. However, when you have too much of it, it puts pressure on your brain and skull. Extra CSF fluid can be caused by different things, such as a brain tumor or it can be present when you’re born. This extra fluid also makes your ventricles grow bigger (see Figure 1). This is called hydrocephalus (hy-dro-ceph-a-lus).
The most common symptoms of hydrocephalus include:
- Fatigue (feeling more tired or weak than usual), drowsiness (not able to stay awake or focus), or both
- Nausea (feeling like you’re going to throw up) and vomiting (throwing up)
- Irritability (feeling angrier than usual)
- Problems with thinking and memory, such as confusion
- Trouble with balance and walking
- Not being able to control when you urinate (pee)
To help drain the extra CSF from your brain, a VP shunt will be placed into your head. The VP shunt works by taking the fluid out of your brain and moving it into your abdomen (belly), where it’s absorbed by your body. This lowers the pressure and swelling in your brain.
A VP shunt has 3 parts (see Figure 2):
- A one-way valve with a reservoir.
- A short catheter (thin, flexible tube)
- A long catheter
The valve controls the flow of CSF fluid. It’s attached on one end to the short catheter so it can drain the fluid away from your brain. The short catheter can be placed in the front, back, or side of your head.
The reservoir collects a small amount of CSF which your doctor can use to sample your CSF for tests if needed.
The long catheter is attached to the other end of the valve. The long catheter is placed under your skin, behind your ear, down your neck, and into your abdomen.
As the VP shunt drains extra CSF and lessens the pressure in your brain, it may ease some of your symptoms. Some symptoms will stop right after the VP shunt is inserted. Others will go away more slowly, sometimes over a few weeks.
The amount of fluid that’s drained by your VP shunt depends on the settings on the shunt. If you have nonprogrammable VP shunt, your doctor will program the settings in advance and they can’t be changed. If you have a programmable VP shunt, the settings can be changed by your doctor if needed.
Your doctor will decide which type of VP shunt is best for you.
VP Shunt Surgery
Your VP shunt surgery will take place in the operating room while you’re asleep.
The surgery will take about 1 hour.
Once you’re asleep, the doctor will shave off some hair near the area where they will make the incision (surgical cut) on your head. Your entire head won’t be shaved.
Your doctor will make 3 small incisions: 1 in your head, 1 in your neck, and 1 in your abdomen. These incisions will help guide the catheter so it can be placed correctly. The doctor will close the incisions with stitches or staples.
You won’t be able to see the catheter because it will be under your skin. However, you may be able to feel the shunt catheter along your neck.
Once all the parts of the shunt are connected, it will start draining the excess CSF as needed to reduce the pressure in your brain.Back to top
Before Your Surgery
The information in this section will help you get ready for your surgery. Read through this section when your surgery is scheduled and refer to it as your surgery date gets closer. It has important information about what you need to do before your surgery.
Write down your questions and be sure to ask your doctor or nurse.
Getting Ready for Your Surgery
You and your healthcare team will work together to get ready for your surgery.
Help us keep you safe during your surgery by telling us if any of the following statements apply to you, even if you aren’t sure.
- I take a blood thinner. Some examples are aspirin, heparin, warfarin (Coumadin®), clopidogrel (Plavix®), enoxaparin (Lovenox®), dabigatran (Pradaxa®), apixaban (Eliquis®), and rivaroxaban (Xarelto®). There are others, so be sure your healthcare provider knows all the medications you’re taking.
- I take prescription medications (medications prescribed by a healthcare provider), including patches and creams.
- I take over-the-counter medications (medications I buy without a prescription), including patches and creams.
- I take dietary supplements, such as herbs, vitamins, minerals, or natural or home remedies.
- I have a pacemaker, automatic implantable cardioverter-defibrillator (AICD), or other heart device.
- I have sleep apnea.
- I have had a problem with anesthesia (medication to make you sleep during surgery) in the past.
- I am allergic to certain medication(s) or materials, including latex.
- I am not willing to receive a blood transfusion.
- I drink alcohol.
- I smoke.
- I use recreational drugs.
About Drinking Alcohol
The amount of alcohol you drink can affect you during and after your surgery. It’s important to talk with your healthcare providers about how much alcohol you drink. This will help us plan your care.
- If you stop drinking alcohol suddenly, it can cause seizures, delirium, and death. If we know you’re at risk for these complications, we can prescribe medications to help keep them from happening.
- If you drink alcohol regularly, you may be at risk for other complications during and after your surgery. These include bleeding, infections, heart problems, and a longer hospital stay.
Here are things you can do before your surgery to keep from having problems:
- Be honest with your healthcare providers about how much alcohol you drink.
- Try to stop drinking alcohol once your surgery is planned. If you develop a headache, nausea (feeling like you’re going to throw up), increased anxiety, or can’t sleep after you stop drinking, tell your healthcare provider right away. These are early signs of alcohol withdrawal and can be treated.
- Tell your healthcare provider if you can’t stop drinking.
- Ask your healthcare provider questions about drinking and surgery. As always, all of your medical information will be kept confidential.
If you smoke, you can have breathing problems when you have surgery. Stopping even for a few days before surgery can help. If you smoke, your nurse will refer you to our Tobacco Treatment Program. You can also reach the program by calling 212-610-0507.
About Sleep Apnea
Sleep apnea is a common breathing disorder that causes you to stop breathing for short periods of time while sleeping. The most common type is obstructive sleep apnea (OSA). With OSA, your airway becomes completely blocked during sleep. OSA can cause serious problems during and after surgery.
Please tell us if you have sleep apnea or if you think you might have it. If you use a breathing machine (such as a CPAP machine) for sleep apnea, bring it with you the day of your surgery.
Within 30 Days of Your Surgery
Presurgical Testing (PST)
Before your surgery, you will have an appointment for presurgical testing (PST). The date, time, and location of your PST appointment will be printed on the appointment reminder from your surgeon’s office.
You can eat and take your usual medications the day of your PST appointment.
During your appointment, you will meet with a nurse practitioner (NP) who works closely with anesthesiology staff (doctors and specialized nurses who will give you anesthesia during your surgery). Your NP will review your medical and surgical history with you. You will have tests, including an electrocardiogram (EKG) to check your heart rhythm, a chest x-ray, blood tests, and any other tests needed to plan your care. Your NP may also recommend that you see other healthcare providers.
Your NP will talk with you about which medications you should take the morning of your surgery.
It’s very helpful to bring the following things to your PST appointment:
- A list of all the medications you’re taking, including prescription and over-the-counter medications, patches, and creams.
- Results of any tests done outside of MSK, such as a cardiac stress test, echocardiogram, or carotid doppler study.
- The name(s) and telephone number(s) of your doctor(s).
Identify Your Caregiver
Your caregiver plays an important role in your care. You and your caregiver will learn about your surgery from your healthcare provider. After your surgery, your caregiver should be with you when you’re given your discharge instructions so they’re able to help you care for yourself at home. Your caregiver will also need to take you home after you’re discharged from (leave) the hospital.
Complete a Health Care Proxy Form
If you haven’t already completed a Health Care Proxy form, we recommend you complete one now. A health care proxy is a legal document that identifies the person who will speak for you if you can’t communicate for yourself. The person you identify is called your health care agent. For more information about health care proxies and other advance directives, read the resource Advance Care Planning.
If you’re interested in completing a Health Care Proxy form, talk with your nurse. If you have completed one already, or if you have any other advance directives, bring them to your next appointment.
Do Breathing and Coughing Exercises
Practice taking deep breaths and coughing before your surgery. You will be given an incentive spirometer to help expand your lungs. For more information, read the resource How to Use Your Incentive Spirometer. If you have any questions, ask your nurse or respiratory therapist.
Try to do aerobic exercise every day. Examples of aerobic exercise include walking at least 1 mile (1.6 kilometers), swimming, or biking. If it’s cold outside, use stairs in your home or go to a mall or shopping center. Exercising will help your body get into its best condition for your surgery and make your recovery faster and easier.
Follow a Healthy Diet
Follow a well-balanced, healthy diet before your surgery. If you need help with your diet, talk with your doctor or nurse about meeting with a clinical dietitian nutritionist.
Tell Us if You’re Sick
If you develop any illness before your surgery, call the doctor who scheduled your surgery. This includes a fever, cold, sore throat, or the flu.
10 Days Before Your Surgery
Stop Taking Vitamin E
If you take vitamin E, stop taking it 10 days before your surgery. Vitamin E can cause bleeding. For more information, read the resource Common Medications Containing Aspirin, Other Nonsteroidal Anti-inflammatory Drugs (NSAIDs), or Vitamin E.
Buy Hibiclens® Skin Cleanser, If Needed
If instructed by your doctor, buy Hibiclens Skin Cleanser. Hibiclens is a skin cleanser that kills germs for 24 hours after you use it (see figure). Showering with Hibiclens before your surgery will help lower your risk of infection after surgery. You can buy Hibiclens at your local pharmacy without a prescription.
7 Days Before Your Surgery
Stop Taking Certain Medications
If you take aspirin, ask your doctor if you should stop taking it. Aspirin and medications that contain aspirin can cause bleeding. You should also stop taking nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil®, Motrin®) and naproxen (Aleve®). These medications should be stopped at least 7 days before your surgery. For more information, read the resource Common Medications Containing Aspirin, Other Nonsteroidal Anti-inflammatory Drugs (NSAIDs), or Vitamin E.
Stop Taking Herbal Remedies and Other Dietary Supplements
Stop taking herbal remedies and other dietary supplements 7 days before your surgery. If you take a multivitamin, ask your doctor or nurse if you should keep taking it. For more information, read the resource Herbal Remedies and Cancer Treatment.
Watch a Virtual Tour
This video will give you an idea of what to expect when you come to Memorial Hospital (MSK’s main hospital) on the day of your surgery.
1 Day Before Your Surgery
Note the Time of Your Surgery
A staff member from the Admitting Office will call you after 2:00 pm the day before your surgery. If your surgery is scheduled for a Monday, they will call you on the Friday before. If you don’t get a call by 7:00 pm, please call 212-639-5014.
The staff member will tell you what time to arrive at the hospital for your surgery. They will also tell you where to go. This will be the following location:
Presurgical Center (PSC) on the 6th floor
1275 York Avenue (between East 67th and East 68th Streets)
New York, NY 10065
B elevator to 6th floor
The Night Before Your Surgery
Shower with Hibiclens, If Needed
If instructed by your doctor, shower with Hibiclens the night before your surgery. Wash behind your ears, neck, and abdomen. Don’t put it on your head or face. For instructions on showering with Hibiclens, read the resource How to Shower Using Hibiclens®. After showering, don’t put any products in your hair such as hair spray or hair gel.
Go to bed early and get a full night’s sleep.
Instructions for eating and drinking before your surgery
Do not eat or drink after midnight.
The Morning of Your Surgery
Take Your Medications
If your doctor or NP told you to take certain medications the morning of your surgery, take only those medications with a sip of water. Depending on what medications you take and the surgery you’re having, this may be all, some, or none of your usual morning medications.
If you didn’t shower the night before with Hibiclens, shower and wash your hair with baby shampoo the morning of your surgery. Don’t use conditioner or any other hair products such as hair spray or hair gel. After showering, don’t put on any lotion, cream, deodorant, makeup, powder, perfume, or cologne.
Things to Remember
- Wear something comfortable and loose-fitting.
- If you wear contact lenses, wear your glasses instead. Wearing contact lenses during surgery can damage your eyes.
- Don’t wear any metal objects. Remove all jewelry, including body piercings. The equipment used during your surgery can cause burns if it touches metal.
- Don’t put on any lotion, cream, deodorant, makeup, powder, perfume, or cologne.
- Leave valuable items (such as credit cards, jewelry, and your checkbook) at home.
- Before you’re taken into the operating room, you will need to remove your hearing aids, dentures, prosthetic device(s), wig, and religious articles.
What to Bring
- Your breathing machine for sleep apnea (such as your CPAP machine), if you have one.
- Your portable music player, if you choose. However, someone will need to hold it for you when you go into surgery.
- Your incentive spirometer, if you have one.
- Your Health Care Proxy form and other advance directives, if you have completed them.
- Your cell phone and charger.
- Only the money you may want for small purchases (such as a newspaper).
- A case for your personal items (such as eyeglasses, hearing aid(s), dentures, prosthetic device(s), wig, and religious articles), if you have one.
- This guide. Your healthcare team will use this guide to teach you how to care for yourself after your surgery.
Where to Park
MSK’s parking garage is located on East 66th Street between York and First Avenues. If you have questions about prices, call 212-639-2338.
To reach the garage, turn onto East 66th Street from York Avenue. The garage is located about a quarter of a block in from York Avenue, on the right-hand (north) side of the street. There’s a tunnel that you can walk through that connects the garage to the hospital.
There are also other garages located on East 69th Street between First and Second Avenues, East 67th Street between York and First Avenues, and East 65th Street between First and Second Avenues.
Once You’re in the Hospital
When you get to the hospital, take the B elevator to the 6th floor and check in at the desk in the PSC waiting room.
You will be asked to say and spell your name and birth date many times. This is for your safety. People with the same or a similar name may be having surgery on the same day.
Get Dressed for Surgery
When it’s time to change for surgery, you will get a hospital gown, robe, and nonskid socks to wear.
Meet With Your Nurse
You will meet with your nurse before surgery. Tell them the dose of any medications (including patches and creams) you took after midnight and the time you took them.
Your nurse may place an intravenous (IV) line into one of your veins, usually in your arm or hand. If your nurse doesn’t place the IV, your anesthesiologist will do it later once you’re in the operating room.
Meet With Your Anesthesiologist
Your anesthesiologist will:
- Review your medical history with you.
- Ask you if you’ve had any problems with anesthesia in the past, including nausea or pain.
- Talk with you about your comfort and safety during your surgery.
- Talk with you about the kind of anesthesia you will have.
- Answer your questions about your anesthesia.
Get Ready for Your Surgery
Once your nurse has seen you, 1 or 2 visitors can keep you company as you wait for your surgery to start. When it’s time for your surgery, your visitor(s) will be taken to the waiting area. Your visitors should read the resource Information for Family and Friends for the Day of Surgery.
You will either walk into the operating room or be taken in on a stretcher. A member of the operating room team will help you onto the operating bed. Compression boots will be placed on your lower legs. These gently inflate and deflate to help blood flow in your legs.
Once you’re comfortable, your anesthesiologist will give you anesthesia through your IV line and you will fall asleep. You will also get fluids through your IV line during and after your surgery.
During Your Surgery
After you’re fully asleep, a breathing tube will be placed through your mouth and into your windpipe to help you breathe. You may also have a urinary (Foley®) catheter placed to drain urine from your bladder.
Once your surgery is finished, your incision will be closed with staples or sutures (stitches). Your incisions may be covered with a bandage. Your breathing tube is usually taken out while you’re still in the operating room.Back to top
After Your Surgery
The information in this section will tell you what to expect after your surgery, both during your hospital stay and after you leave the hospital. You will learn how to safely recover from your surgery.
Write down your questions and be sure to ask your doctor or nurse.
In the Post-Anesthesia Care Unit (PACU)
When you wake up after your surgery, you will be in the Post-Anesthesia Care Unit (PACU).
A nurse will be monitoring your body temperature, pulse, blood pressure, and oxygen levels. You may be getting oxygen through a thin tube that rests below your nose or a mask that covers your nose and mouth. You will also have compression boots on your lower legs.
While you’re in the PACU, your pain will be managed with medications.
Your visitors can see you briefly in the PACU, usually within 90 minutes after you arrive there. A member of the nursing staff will explain the guidelines to them.
Moving to Your Hospital Room
Once you recover from the anesthesia, you will be taken to your hospital room. The length of time you will stay in the PACU may also depend on when your hospital bed is ready for you.
In Your Hospital Room
The length of time you’re in the hospital after your surgery depends on your recovery. Most people stay in the hospital for 1 to 2 days.
When you’re taken to your hospital room, you will meet one of the nurses who will care for you while you’re in the hospital. While you’re in the hospital, your nurses will teach you how to care for yourself while you’re recovering from your surgery.
For the first few days after your surgery, your nurses will do simple tests to make sure your brain is working well. They will do things such as:
- Ask you questions such as where you are and what time of day it is.
- Ask you to move your arms and legs.
- Shine a small light into your eyes to check the response of your pupils.
Read the resource Call! Don't Fall! to learn about what you can do to stay safe and keep from falling while you’re in the hospital.
Managing Your Pain
You may have a mild headache or feel discomfort around your incision for the first few days after your surgery.
At first, you will get pain medication in your IV line. Once you’re able to eat normal food, you will get oral pain medication (medication you swallow).
Your doctor and nurse will ask you about your pain often and give you medication as needed. If your pain isn’t relieved, tell your doctor or nurse. It’s important to control your pain so you can use your incentive spirometer and move around. Controlling your pain will help you recover better.
You will be given a prescription for pain medication before you leave the hospital. Talk with your doctor or nurse about possible side effects and when you should start switching to over-the-counter pain medications.
Moving Around and Walking
Moving around and walking will help lower your risk for blood clots and pneumonia. It will also help stimulate your bowels so they start working again. Your nurse, physical therapist, or occupational therapist will help you move around if needed.
Exercising Your Lungs
It’s important to exercise your lungs so they expand fully. This helps prevent pneumonia.
- Use your incentive spirometer 10 times every hour you’re awake. For more information, read the resource How to Use Your Incentive Spirometer.
- Do coughing and deep breathing exercises. A member of your care team will teach you how to do these exercises.
Eating and Drinking
You will be given ice chips to eat after your surgery. You will start with a liquid diet and then you can start eating your normal foods again, as tolerated.
If you have questions about your diet, ask to see a clinical dietitian nutritionist.
To make sure your shunt is in the right place, you may have a computed tomography (CT) scan (imaging scan) of your head 1 to 2 days after your surgery. Your nurse will give you more information about the scan before it’s done.
Caring for Your Incision
You will have bandages over your incision. Your doctor will take them off 1 to 2 days after your surgery. After that, you can leave them uncovered. Don’t get your incision wet, and don’t put any lotions, creams or powders on it for 5 days after your surgery.
Planning for Your Discharge
A physical therapist will work with you before you leave the hospital and help decide if you need help at home, such as special medical equipment or a home care nurse. If needed, your case manager will work with you to arrange for home care visits after you’re discharged from the hospital.
A caregiver should help you at home for a few days after your surgery while you recover.
Leaving the Hospital
By the time you’re ready to leave the hospital, your incision will have started to heal. Before you leave the hospital, look at your incision with your nurse and caregiver. Knowing what your incision looks like will help you notice any changes later.
On the day of your discharge, you should plan to leave the hospital around 11:00 am. Before you leave, your doctor will write your discharge order and prescriptions. You will also get written discharge instructions. Your nurse will review these instructions with you before you leave.
If your ride isn’t at the hospital when you’re ready to be discharged, you may be able to wait in the Patient Transition Lounge. A member of your healthcare team will give you more information.
Read the resource What You Can Do to Avoid Falling to learn about what you can do to stay safe and keep from falling at home and during your appointments at MSK.
Managing Your Pain
People have pain or discomfort for different lengths of time. You may still have some pain when you go home and will probably be taking pain medication. Some people have soreness, tightness, or muscle aches around their incision for 6 months or longer. This doesn’t mean that something is wrong.
Follow the guidelines below to help manage your pain at home.
- Take your medications as directed and as needed.
- Call your doctor if the medication prescribed for you doesn’t ease your pain.
- Don’t drive or drink alcohol while you’re taking prescription pain medication.
- As your incision heals, you will have less pain and need less pain medication. An over-the-counter pain reliever such as acetaminophen (Tylenol®) or ibuprofen (Advil®) will ease aches and discomfort.
- Follow your doctor or nurse’s instructions for stopping your prescription pain medication.
- Don’t take more acetaminophen than the amount directed on the bottle or as instructed by your doctor or nurse. Taking too much acetaminophen can harm your liver.
- Pain medication should help you resume your normal activities. Take enough medication to do your exercises comfortably. However, it’s normal for your pain to increase a little as you start to be more active.
- Keep track of when you take your pain medication. It works best 30 to 45 minutes after you take it. Taking it when your pain first begins is better than waiting for the pain to get worse.
Pain medication may cause constipation (having fewer bowel movements than what’s normal for you).
Caring for Your Incisions
- Check your incisions daily for any signs of infection, including redness, swelling, or drainage.
- Keep your incisions clean and dry for 5 days after your surgery. Don’t shower for 5 days after your surgery. Avoid baths, hot tubs, and swimming pools until your doctor tells you it’s okay.
- Don’t use a hair dryer, creams, ointment, or hair products on your incisions until they’re completely healed. This takes about 6 weeks.
It’s normal for the skin below your incisions to feel numb. This happens because some of your nerves were cut during your surgery. The numbness will go away over time.
Call your doctor’s office if:
- The skin around your incisions is very red.
- The skin around your incisions is getting more red.
- You see drainage that looks like pus (thick and milky).
If you go home with staples or stitches in your incisions, your doctor will take them out during your first appointment after surgery. This is usually 7 to 10 days after your surgery.
Do not shower for 5 days after your surgery. You may take a sponge bath during this time, but don’t get your incision wet. Don’t use dry shampoo, creams or lotions near your incisions.
After 5 days, take a shower every day to clean your incision. If you have staples in your incision, it’s okay to get them wet.
Use a mild shampoo, such as baby shampoo and soap during your shower.
After you shower, pat the area dry with a clean towel and leave your incision uncovered. Don’t put any creams, lotions, or powders on your incision.
Physical Activity and Exercise
When you leave the hospital, your incision will look like it’s healed on the outside, but it won’t be healed on the inside. For the first 4 to 6 weeks after your surgery:
- Don’t lift anything heavier than 10 pounds (about 4.5 kilograms).
- Don’t do any strenuous activities (such as jogging and tennis).
- Don’t play any contact sports (such as football).
Doing aerobic exercise, such as walking and stair climbing, will help you gain strength and feel better. Walk at least 2 to 3 times a day for 20 to 30 minutes. You can walk outside or indoors at your local mall or shopping center.
It’s normal to have less energy than usual after your surgery. Recovery time is different for each person. Increase your activities each day as much as you can. Always balance activity periods with rest periods. Rest is an important part of your recovery.
Ask your doctor when you can drive. Most people can start driving again 4 to 6 weeks after surgery. Don’t drive while you’re taking pain medication that may make you drowsy. You can ride in a car as a passenger at any time after you leave the hospital.
Going back to work
Talk with your doctor or nurse about your job and when it may be safe for you to start working again. If your job involves lots of movement or heavy lifting, you may need to stay out a little longer than if you sit at a desk.
You can travel by bus, train or car. Don’t travel on an airplane until your doctor says it’s okay.
When traveling a long distance, don’t sit for long periods of time. Stop every 2 hours and walk around. This will help keep blood clots from forming in your legs.
Managing Your Feelings
After surgery for a serious illness, you may have new and upsetting feelings. Many people say they felt weepy, sad, worried, nervous, irritable, and angry at one time or another. You may find that you can’t control some of these feelings. If this happens, it’s a good idea to seek emotional support.
The first step in coping is to talk about how you feel. Family and friends can help. Your nurse, doctor, and social worker can reassure, support, and guide you. It’s always a good idea to let these professionals know how you, your family, and your friends are feeling emotionally. Many resources are available to you and your family. Whether you’re in the hospital or at home, the nurses, doctors, and social workers are here to help you and your family and friends handle the emotional aspects of your illness.
MyMSK (my.mskcc.org) is your MSK patient portal account. You can use MyMSK to send and receive messages from your healthcare team, view your test results, see your appointment dates and times, and more.
If you don’t already have a MyMSK account, you can sign up by going to my.mskcc.org. For more information about signing up for a MyMSK account, watch our video How to Enroll in the Patient Portal: MyMSK. You can also contact the MyMSK Help Desk by emailing firstname.lastname@example.org or calling 800-248-0593.
Going back to your normal activities
You can go back to doing your normal activities when your doctor tells you it’s okay. If you plan to exercise, ask your doctor if it’s safe.
You will then have regular visits with your neurologist, neurosurgeon, or both. They will check on the function of your VP shunt over time.Back to top
Safety Precautions for Your VP Shunt
Precautions with magnets
The pressure setting of some VP shunts may accidentally change if you get too close to a magnet. This depends on the VP shunt model.
Ask your doctor if you need to take precautions (safety measures) when coming into contact with magnets. Be sure to follow the VP shunt manufacturer’s guidelines for magnet precautions specific for your type of shunt. Your doctor will go over these guidelines with you.
Here are some general rules for many shunts:
- Keep all products with magnets at least 2 inches away from the valve implant site (your head).
- Don’t use magnetic therapy pads and pillows.
Precautions with magnetic resonance imaging (MRI)
If you need to have magnetic resonance imaging (MRI), you must tell your MRI technologist that you have a VP shunt before you have the test. Your technologist will need to know the model of your shunt and its setting.
Your nurse will give you a wallet card with this information. Carry it with you at all times. You can show your technologist the wallet card.
Depending on the type of VP shunt you have, the magnet in the MRI machine may change your shunt’s pressure setting. In this case, after your MRI, the pressure setting will need to be checked and may need to be reprogrammed by your doctor or nurse practitioner. In some cases, you may need to have x-rays to find out if the pressure setting has changed.
Some types of VP shunts aren’t affected by MRI. Ask your doctor or nurse if your shunt will need to be reprogrammed after an MRI. No matter what type of VP shunt you have, you won’t need to take any precautions if you’re having a computed tomography (CT) scan, positron emission tomography (PET) scan, or an x-ray.
If your VP shunt needs to be reprogrammed after you have an MRI, you must schedule an appointment with your doctor or nurse to reprogram your VP shunt after your MRI.Your shunt should be reprogrammed within 4 hours after your MRI.
Precautions for abdominal surgery
If you ever need to have abdominal surgery, you must tell your doctor so that precautions can be taken. Tell your doctor if you have peritonitis (a condition in which the tissue that covers your abdomen is inflamed) or diverticulitis (a condition in which small, bulging pouches develop in the intestines or colon) and you need emergency surgery or antibiotics..
You should always wear a MedicAlert® bracelet or necklace that says you have hydrocephalus and a VP shunt. If you’re ever very sick or hurt and need medical help, MedicAlert jewelry will let emergency service workers know about your VP shunt.
You can purchase this type of bracelet or necklace at most drug stores. For more information, visit the MedicAlert® website at: www.medicalert.org.Back to top
Contact your doctor or nurse if:
Call your doctor or nurse if you have any of the following signs and symptoms that your VP shunt isn’t working properly:
- Vomiting with little or no nausea
- A constant headache that won’t go away
- Problems with your vision (eyesight) (blurry vision, double vision, or loss of vision)
- Loss of coordination or balance
- Swelling, redness, or both, of the skin that runs along the shunt path
- Difficulty waking up or staying awake
Call your doctor or nurse if you have signs and symptoms of a VP shunt infection.
A VP shunt infection can happen when bacteria infect the tissue around your VP shunt. When the tissue is infected, it can cause your VP shunt to stop working properly and increase pressure in your brain.
The signs and symptoms of a VP shunt infection include:
- A fever of 100.4° F (38° C) or higher
- Redness, swelling, or both, of the skin that runs along the shunt path
- Pain around the shunt or around the shunt catheter from the head to the abdomen
These warning signs can happen quickly. If any of these symptoms develop, call your doctor or nurse immediately.
