Endoscopic third ventriculostomy (ETV) is a surgical procedure used to treat obstructive hydrocephalus, a condition characterized by the accumulation of cerebrospinal fluid (CSF) in the brain. CSF is produced in the ventricular system of the brain, which consists of four cavities - two lateral ventricles, the third ventricle, and the fourth ventricle - interconnected by channels.
The third ventricle, situated centrally above the base of the skull, plays a crucial role in CSF circulation. In cases of obstructive hydrocephalus, CSF flow is impeded due to blockage, often occurring at the passage between the third and fourth ventricles, known as the cerebral aqueduct.
ETV involves creating a new pathway for CSF to bypass the blockage by making a small hole in the floor of the third ventricle using an endoscope. This allows CSF to flow directly into the subarachnoid space surrounding the brain, relieving pressure and reducing ventricle enlargement.

After surgery, your child will recover in the Post Anesthesia Care Unit (PACU) or the Pediatric Intensive Care Unit (PICU). Your doctor will provide updates on your child’s condition, and the staff will inform you when you can join your child in the PACU or ICU room.
Children usually stay in the hospital for two to three days and can go home once the surgeon confirms the surgery was effective and the following conditions are met:
Your child will need to visit the neurosurgery clinic about two weeks after surgery for a wound check. Depending on the doctor’s preference, an MRI or CT scan may be required before this visit to assess the cerebrospinal fluid (CSF) spaces. Follow-up scans at the three-month mark will determine if the surgical opening remains patent.
