It is a good idea for a person who has a ventriculoperitoneal shunt to wear a medical bracelet to alert people in case of an emergency.Normally we image the IVC to give us a ballpark assessment of a patient’s volume status, and preload to the right heart. Similarly, if a person has surgery on their abdomen in the future, they should let the doctor know they have a ventriculoperitoneal shunt. If a person needs to have an MRI scan in the future, they should let the MRI operator know that they have a ventriculoperitoneal shunt. Sometimes earphones may affect the effectiveness of a ventriculoperitoneal shunt, so it is a good idea to check the shunt manufacturer’s guidelines before using them. Magnetic fields may affect how the valve on the shunt works. If a person has any signs of infection, they should see a doctor straight away.Īfter having a ventriculoperitoneal shunt inserted, a person should avoid coming into contact with magnets. It is also possible for the ventriculoperitoneal shunt to become infected. If the pump does not drain CSF quickly enough, the symptoms of hydrocephalus might return. If the pump drains CSF faster than the body produces it, a person may experience a brain hemorrhage. If a ventriculoperitoneal shunt stops working correctly, it is possible for it to over- or underdrain CSF. redness or swelling where the catheter passes under the skin.Signs that the device is not working as it should include: Sometimes a ventriculoperitoneal shunt may stop working correctly and need replacing. But some people may experience adverse effects, including: Going under general anesthetic is safe for most people. The following factors can cause hydrocephalus:Ī person with hydrocephalus may experience the following symptoms: an obstruction that stops CSF draining properly.When a person has hydrocephalus, it may mean that there is: Hydrocephalus may cause brain damage or death if left untreated.Īccording to the Hydrocephalus Association, over 1 million people in the United States have the condition. Excess CSF pools in the brain ventricles, which increases the pressure on the brain. When a person has hydrocephalus, this process does not happen correctly. It then drains out of the base of the brain, and the blood reabsorbs it. To do this, CSF passes through cavities in the brain called ventricles, bathing the brain in the fluid. Hydrocephalus is a condition where cerebrospinal fluid (CSF) pools in the cavities in a person’s brain.ĬSF delivers essential nutrients to the brain and drains away waste. A programmable shunt, however, has an external, adjustable valve that the doctor can readjust at any time according to the person’s needs.ĭoctors often use a ventriculoperitoneal shunt to treat hydrocephalus, which is also known as water on the brain. It is not possible to adjust a nonprogrammable shunt after insertion. With a nonprogrammable shunt, the doctor programs the valve so that it activates whenever the fluid reaches a certain volume. There are two types of ventriculoperitoneal shunt The valve, also known as a pump, controls the shunt so that it drains fluid as needed. The other runs under the skin, taking the fluid to a drainage site elsewhere in the body. One catheter drains fluid from the brain out of a small hole the doctor makes in the skull. Ventriculoperitoneal shunts consist of a valve and two tubes, called catheters, which drain the fluid. A ventriculoperitoneal shunt drains excess brain fluid, reducing brain pressure to a safe level. Fluid buildup can increase brain pressure, which can be harmful. The purpose of a ventriculoperitoneal shunt is to remove excess fluid from a person’s brain. Share on Pinterest A ventriculoperitoneal shunt is either programmable or nonprogrammable.
