Endoscopic Third Ventriculostomy (ETV) is a less invasive surgical procedure than shunt placement. ETV is usually only done in patients with certain types of hydrocephalus and is not suitable for all individuals.
ETV is a minimally invasive treatment option for hydrocephalus, without involving a shunt. It is only relevant for individuals where their condition follows certain criteria.
ETV uses a tiny camera called a neuro-endoscope and tiny surgical instruments to make an opening in the floor of the brain’s third ventricle, traditionally a difficult area to reach via surgery. This fibre optic technology allows the neurosurgeon to view the surface of the ventricle. This opening allows CSF to flow out of the ventricles and into the normal pathways of the brain, flowing freely through the ventricular system, reducing the pressure within the brain.
When this procedure is successful, neither a shunt nor further treatment is usually required.
The procedure is minimally invasive and has a lower risk of complications and a shorter recovery time than shunt surgery but is only suitable for particular types of hydrocephalus that meet certain criteria.
