Hydrocephalus, commonly called “water on the brain,” occurs when cerebrospinal
fluid (CSF) accumulates, increasing pressure inside the skull. Traditionally,
this condition is treated with a ventricular shunt, a device that diverts
fluid to another part of the body. At IGEA Brain, Spine, Pain & Orthopedics,
we offer Endoscopic Third Ventriculostomy (ETV)—a minimally invasive procedure
that creates a natural pathway for CSF drainage, eliminating or reducing the
need for a permanent shunt.
What Is Endoscopic Third Ventriculostomy?
ETV is a surgical technique in which a tiny endoscope is inserted into the
ventricles of the brain. A small opening is made in the floor of the third
ventricle, allowing CSF to flow into the subarachnoid space, where it can be
naturally absorbed.
Benefits of ETV Over Shunt Placement
-
Avoids a permanent implant: No plastic tubing or long-term shunt maintenance
-
Reduces infection and malfunction risks: Shunts can become blocked or
infected over time
-
Minimally invasive: Small incision and endoscopic approach allow for faster
recovery
-
Durable solution: Often long-lasting, especially in select types of
hydrocephalus
Who Is a Candidate?
ETV is generally considered for patients with:
-
Obstructive hydrocephalus: Blockage of CSF flow within the ventricular
system
-
Communicating hydrocephalus: Sometimes, in combination with other procedures
-
Patients seeking shunt alternatives: Especially those prone to shunt
complications
The Procedure
- Preoperative Imaging: MRI or CT maps the ventricles and CSF pathways
-
Endoscopic Access: A small burr hole is made in the skull for the endoscope
-
Creating the Ventricular Opening: A tiny hole in the third ventricle floor
allows CSF to bypass obstruction
-
Recovery: Short hospital stay and careful monitoring; most patients resume
normal activities faster than with traditional shunts
Contact IGEA for Advanced Hydrocephalus Care
If you or a loved one has hydrocephalus or increased intracranial pressure,
contact IGEA Brain, Spine, Pain & Orthopedics. Our neurosurgeons evaluate your
condition and discuss whether ETV, a shunt, or a hybrid approach is the safest
and most effective option.
