Babies younger than 1 year old still have their “soft spot” because their skull bones have not fully grown together yet. In them, hydrocephalus usually leads to bulging at the soft spot, increasing head size, and large scalp veins. Older children with hydrocephalus usually complain of headache.

Hydranencephaly is a rare birth defect that drastically affects brain development. Babies born with this neurological condition are missing the right and left hemispheres of the cerebrum. The cerebrum normally forms the front of the brain.

Hydrocephalus is typically detected through a prenatal ultrasound between 15 and 35 weeks gestation. Our specialists are able to confirm this diagnosis with a fetal magnetic resonance imaging (MRI) exam, which provides more detailed images of the brain.

Surgery may be needed for some cases of hydrocephalus. Surgery usually involves placing a mechanical shunting device into the baby’s head to help drain the extra CSF from the brain and redirect the extra fluid to another part of the body to be absorbed. A common type of shunt is the ventriculoperitoneal shunt.

Most of the newborns born with hydrocephalus will have a normal lifespan, and approximately 40 to 50 percent will have normal intelligence. Seizure disorders have been diagnosed in about 10 percent of children with hydrocephalus. The mortality rate for infants is approximately 5 percent.

Hydrocephalus typically affects visual acuity, coordination, judgment, and concentration, all of the skills which are necessary to drive. Just learning how to coordinate between controlling the steering wheel and applying the accelerator or brake can be a daunting task when you have poor motor skills.

After making a small hole in the floor of your brain to drain the fluid, the endoscope is removed and the wound is closed using stitches. The procedure takes around 1 hour.

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’ll make the incision (surgical cut) on your head.

A shunt blockage can be very serious as it can lead to an build-up of excess fluid in the brain, which can cause brain damage. This will cause the symptoms of hydrocephalus. Emergency surgery will be needed to replace the malfunctioning shunt.

Shunt Malfunction Signs

• Headaches.
• Vomiting.
• Lethargy (sleepiness)
• Irritability.
• Swelling or redness along the shunt tract.
• Decreased school performance.
• Periods of confusion.
• Seizures.

In many cases, diagnostic imaging, such as CT scans or X-rays, is performed to rule in or rule out shunt dysfunction. These imaging tests expose patients to radiation, and many times these tests indicate that the shunt is in fact working properly.

A shunt blockage from blood cells, tissue, or bacteria can occur in any part of the shunt. Both the ventricular catheter (the portion of the tubing placed in the brain) and the distal part of the catheter (the tubing that drains fluid to another part of the body) can become blocked by tissue.

A shunt is simply a device that diverts CSF around the obstructed pathways. This stops it accumulating and returns it to the bloodstream. It consists of a system of tubes with a valve to control the rate of drainage and prevent back-flow.

However, people with LP shunts should avoid any activity which involves twisting at the waist, as this can dislodge the shunt.

• Martial arts. Any activity that involves being grabbed around the neck is not advised, as the shunt tubing in the neck can crack.
• Rugby.
• Gymnastics and dance.
• Water sports.
• Golf.
• Other activities.

It is possible that the puncture of the ventricle or the opening of the dura will result in an intracranial hemorrhage. It is possible that if too much CSF is removed from the ventricles, either during a drainage procedure or when the ventricle is first punctured, the ventricle may collapse and occlude the catheter.
