Endoscopic Third Ventriculostomy

What is endoscopic third ventriculostomy?

Endoscopic third ventriculostomy (ETV) is a minimally invasive procedure that uses an endoscope to treat obstructive hydrocephalus, a condition caused by excess build-up of cerebrospinal fluid (CSF), a protective layer found around the brain and spinal cord in the brain.

Obstructive hydrocephalus (also known as non-communicating hydrocephalus) occurs when the fluid is unable to flow properly between the ventricles. This usually happens due to a narrowing of the passage between the ventricles.

The endoscope is used to create an alternate pathway for CSF to flow from the brain downwards to the spine, because the normal pathway through the aqueduct is blocked.

Why do you need an endoscopic third ventriculostomy?

An ETV is considered the treatment of choice for patients diagnosed to have obstructive hydrocephalus, which is caused by blockage in the normal pathways of CSF flow. This leads to excessive CSF in the brain. It is usually caused by congenital or acquired aqueduct stenosis or tumour.

The general benefits of an endoscopic third ventriculostomy are:

  • It is a minimally invasive procedure.
  • It eliminates the need of placing a shunt, which is a small silicone tube that carries cerebrospinal fluid to a different body cavity for reabsorption.

Endoscopic third ventriculostomy success rate

The success rate for an ETV depends on factors such as:

  • Age of the patient
  • Cause of hydrocephalus

For some patients, the success rate may be up to 90%. However, for some, the chances for success may be lower in children under the age of 2.

What are the risks and complications of an endoscopic third ventriculostomy?

Risks associated with the procedure may include:

  • Bleeding from damage to the arteries
  • Fever
  • Formation of a haematoma (blood clot)
  • Neural injuries (e.g. thalamus, fornix, hypothalamus, mid-brain)
  • Leakage of cerebrospinal fluid

Short-term memory loss and endocrine abnormalities may also occur, although both recover with time.
