What are the different types of shunts for hydrocephalus?

What Is a Shunt? Shunt for Hydrocephalus

• A ventriculoperitoneal shunt moves fluid from the ventricles of the brain to the abdominal cavity.
• A ventriculoatrial shunt moves fluid from the ventricles of the brain to a chamber of the heart.
• A lumboperitoneal shunt moves fluid from the lower back to the abdominal cavity.

How long do shunts for hydrocephalus last?

Shunting is successful in reducing pressure in the brain in most people. VP shunts are likely to require replacement after several years, especially in small children. The average lifespan of an infant’s shunt is two years. Adults and children over the age of 2 may not need a shunt replacement for eight or more years.

What are CSF shunts?

Placement of cerebral spinal fluid (CSF) shunt systems to treat hydrocephalus is a common medical procedure and a life-saving treatment for many patients. These shunt systems drain excess fluid from the brain to another part of the body where the fluid is absorbed as part of the circulatory process.

What are shunts used for in the brain?

A shunt is a hollow tube surgically placed in the brain (or occasionally in the spine) to help drain cerebrospinal fluid and redirect it to another location in the body where it can be reabsorbed.

Does a shunt stay in forever?

VP shunts do not work forever. When the shunt stops working: The child can have another buildup of fluid in the brain. Another surgery is needed to fix it.

How often should shunts be checked?

All younger patients with a shunt should probably be encouraged to seek a neurosurgical check up at least every three years, ideally at a dedicated hydrocephalus follow up clinic.

How often do VP shunts fail?

It’s estimated up to 4 in 10 shunts will malfunction in the first year after surgery. Sometimes, a scan after the operation shows the shunt is not in the best position and further surgery is needed to reposition it.

What are the side effects of a shunt?

Shunt infection

• redness and tenderness along the line of the shunt.
• a high temperature.
• headache.
• vomiting.
• neck stiffness.
• tummy pain if the shunt drains into your tummy.
• irritability or sleepiness in babies.

Do VP shunts stay in forever?

VP shunts do not work forever. When the shunt stops working: The child can have another buildup of fluid in the brain.

How often do shunts fail?

The risk of shunt failure is greatest within the first year of insertion, estimated to be 10% to 20%, depending on the underlying cause of the hydrocephalus. The subsequent failure rate is about 5% per year after this. Infection is a dreaded complication, especially in patients who are shunt dependent.

How does a shunt treat normal pressure hydrocephalus (NPH)?

How is normal pressure hydrocephalus treated? A commonly used treatment for NPH is surgery to place a tube, called a shunt, into the brain to drain the excess fluid . The shunt is usually inserted into a ventricle in the brain and then passed under your skin from your head through your neck and chest to your abdomen.

What is the recovery time after brain shunt surgery?

You may need to stay in hospital for a few days after the operation to recover. A shunt is a hollow tube surgically placed in the brain (or occasionally in the spine) to. Hydrocephalus symptoms may improve within days of shunt surgery, or may take weeks to.

What are the problems with a shunt?

Shunt infection is a common problem and can occur in up to 27% of patients with a shunt. Infection can lead to long term cognitive defects, neurological problems, and in some cases death. Common microbial agents for shunt infection include Staphylococcus epidermidis , Staphylococcus aureus , and Candida albicans .

What are the side effects of shunt placement?

Unlike most surgical procedures, in which the risks are highest during the operation itself, most of the common problems associated with shunting can and do occur at a later time. The most common complications with shunting are obstruction, infection, and overdrainage of cerebrospinal fluid.
