ENDOSCOPIC THIRD VENTRICULOSTOMY (ETV)

Endoscopic third ventriculostomy is a surgical procedure used to treat hydrocephalus and may eliminate the need for a ventriculoperitoneal shunt that is an implant used to divert cerebrospinal fluid (CSF).

WHEN IS ENDOSCOPIC THIRD VENTRICULOSTOMY NECESSARY?

An endoscopic third ventriculostomy is a procedure done to treat hydrocephalus. Hydrocephalus may arise for many different reasons; however, when there is an obstruction to flow of CSF in conditions such as tumours or aqueduct stenosis an ETV is the procedure of choice.  

HOW IS THIS SURGERY DONE?

The aim of this procedure is to create a hole in the floor of the third ventricle to allow CSF to drain from the brain. Prior to surgery, MRI scans are used to diagnose the condition and assess whether an ETV will be suitable. 

During an endoscopic third ventriculostomy, Dr Profyris will use an endoscope fitted with a camera to perform the surgery. The operation is performed through a very small incision and hole in the skull.  The endoscope is inserted into the brains water system and then directed toward the third ventricle.  An opening is made in a thin membrane at the floor of the third ventricle and will relieve the obstruction by allowing CSF to flow below the base of the brain, over the surface of the brain where it can be reabsorbed by the body.
