Endoscopic Third Ventriculostomy
for Obstructive Hydrocephalus

What is Obstructive Hydrocephalus? (hydro=water, cephalus=head)
This is an increase of cerebral spinal fluid (CSF) in the brain. This happens when there is a
blockage of CSF flow within the brain. The blockage prevents CSF from getting to areas where
it will be reabsorbed. Tumors, cysts, or birth defects can cause this blockage.

When CSF collects in the brain, the pressure in the brain rises. Increased brain pressure can
damage brain tissue. Symptoms of increased brain pressure include:

 Headache  Feeling sleepy
 Vomiting  Blurred or double vision
 Irritability  Increase in infant’s head size
 Decrease in
 “Sunset eyes” (eyes which only look down)
 Clumsiness in older kids and adults

Normal CSF Flow Obstructive Hydrocephalus

Brain surgery treats obstructive hydrocephalus. There are two surgeries for this.

 A VP (Ventriculo-Peritoneal) Shunt is placed into a ventricle of the brain.
 The shunt is a narrow piece of tubing that drains extra CSF from the brain to the
area around the stomach (called the “peritoneum”).
 The CSF is absorbed in the peritoneum.
 In VP Shunt surgery, a small hole is made in the skull bone.
 Shunt tubing is placed through the hole into the ventricle in the brain.
 The tubing starts in the ventricle. Then it goes to a one way valve under the skin.
Then the tubing that goes to the peritoneum it attached to the valve.
 A small incision is also made in the stomach region where the tubing ends.

 An Endoscopic Third Ventriculostomy (ETV) can be made to allow CSF to flow
around the blockage and be reabsorbed.
 A small hole is made in the skull bone.
 A small camera (called an “endoscope”) is placed through this hole.
 The camera views the parts of the brain and the blockage.
 Next, a laser is used to make a small hole in the floor of the third ventricle.
 The CSF will go through the hole and around the blockage

Before Surgery
 You will need a physical exam, health review, and lab tests.
 Please stop aspirin and ibuprofen for two weeks before surgery. It is alright to use
acetaminophen (Tylenol®) if needed.
 You will wash with Sage clothes as instructed.
 You will receive a phone call the day before surgery telling you when to stop eating and
 Do not wear make-up, jewelry, or nail polish to surgery.

After Surgery
 There is mild pain involved with this. Pain relievers can be used to increase comfort.
 When you are eating and drinking normally, you will go home.
 Plan for a 3 to 5 day hospital stay.
 You will have a bandage on your head when you go home. You will need to keep this dry
and clean.
 You will have a clinic visit in 7-10 days. Your bandage and staples will be removed at this
 You should wait at least two weeks after surgery before getting any immunizations.
 You will always need regular follow-up with a neurosurgeon. You will also need MRI
scans to check the size of the ventricles.

When to Call the Neurosurgeon or Nurse Practitioner
Increased pressure in the brain can occur after surgery. Please call right away if you notice any of
these signs and symptoms.
 Frequent headaches or rubbing of the head in young infants.
 Loss of appetite, nausea, or vomiting.
 Irritability
 Feeling sleepy
 Irritability
 Blurred vision
 Sunset eyes
 Clumsiness or balance problems
 Worsening school performance
 Drainage from a wound
 Redness, pain, swelling or drainage at the wound sites
 Sudden or slow change in personality
