Endoscopic third ventriculostomy is also an option.

In one case study, an endoscopic third ventriculostomy was performed as a first line procedure to treat the hydrocephalus and also for diagnostic purposes.

An 11-year-old girl in one incident developed peduncular hallucinosis, which included disturbed sleep, after an endoscopic third ventriculostomy was performed on her.

For example, a "third ventriculostomy" is a neurosurgical procedure that creates a hole in the floor of the third ventricule and usually has no indwelling objects.

Jones et al. have treated 4 patients with non-communicating hydrocephalus that suffered VP shunt infections with shunt removal and third ventriculostomy.

He described the surgical technique of ventriculocisternostomy (lateral ventricle to cisterna magna,; a predecessor of today's endoscopic third ventriculostomy), which is also called "Torkildsen's operation".

Endoscopic third ventriculostomy (ETV) is a surgical procedure in which an opening is created in the floor of the third ventricle using an endoscope placed within the ventricular system through a burr hole.

An alternative treatment for obstructive hydrocephalus in selected patients is the endoscopic third ventriculostomy (ETV), whereby a surgically created opening in the floor of the third ventricle allows the CSF to flow directly to the basal cisterns, thereby shortcutting any obstruction, as in aqueductal stenosis.
