Endoscopic Third Ventriculostomy

Endoscopic Third Ventriculostomy

Endoscopic Third Ventriculostomy is a treatment for obstructive hydrocephalus. Hydrocephalus is a condition of increasing cerebrospinal fluid in the brain. It is an alternative procedure to shunt surgery for the treatment of hydrocephalus.

  • Obstructive hydrocephalus, occurs when the flow of CSF is blocked or obstructed.
  • A small hole is made in the skull.
  • An endoscope using small camera is guided into the brain through this hole to identify ventricular surface.
  • When ventricular surface is identified, a tiny perforation is made in the floor of third ventricle.
  • This will create a pathway for CSF and allow it to flow from the blocked ventricles into the cavities in the brain.
  • ETV restores the flow of cerebrospinal fluid in the brain.
  • After all the steps are performed, the wound will be closed with thorough care.


The main advantages of ETV are;

  • It does not leave or implant any mechanical device inside your brain
  • Risk of infection is comparatively less than shunt surgery.
  • Usually ETV is not performed in patients below 2 years old as its success rate in infants is less.

At the same time, this surgery may not be effective in all other patients with obstructive hydrocephalus.

Complications of ETV

  • Inability of brain to re-absorb CSF
  • Hole closure
  • Chance of infection, but lesser
  • Bleeding inside your brain
  • Vision problems
  • Weakness down one side of the body

After Surgery

Pain relievers can be used to get comfort

Keep your wound area dry and clean

Re-visit to clinic after a week for removal of dressings and observing progress. You might have to do regular follow-ups as per the suggestions of your doctor.
