third ventriculostomy

third ven·tric·u·los·to·my

an operation to establish an opening from the third ventricle to the prechiasmal and interpeduncular cisterns (Stookey-Scarff operation) or from the third ventricle to the interpeduncular cistern (Dandy operation).

third ventriculostomy

[ventrik′yəlos′təmē]
Etymology: L, tertius, three, ventriculus, little belly; Gk, stoma, mouth
a surgical procedure for draining cerebrospinal fluid into the cisterna chiasmatis of the subarachnoid space in hydrocephalus, usually in the newborn. The procedure is not commonly performed and is used chiefly when the cisterna magna is not available for ventriculocisternostomy. The third ventriculostomy makes an opening on the anterior wall of the floor of the third ventricle into the interpeduncular cistern and is performed to correct an obstructive type of hydrocephalus.

Endoscopic third ventriculostomy (ETV) has been largely accepted as the treatment of choice for the patients with non-communicating hydrocephalus caused by congenital or acquired aqueductal stenosis or obstruction [1,2], due to the low failure rate and less associated morbidity than other therapy modalities, e.

Conclusions: Preoperative endoscopic third ventriculostomy (ETV) control the intracranial pressure (ICP), avoid the necessity of an emergency procedure, allow appropriate scheduling of the operation for tumor removal, and eliminate the risks related to the presence of an external drainage.
