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
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.
