Endoscopic Third Ventriculostomy (ETV) in India

What is Endoscopic Third Ventriculostomy (ETV)?

Endoscopic Third Ventriculostomy (ETV) is a minimally invasive neuroendoscopic procedure that creates a small fenestration in the floor of the third ventricle, allowing trapped cerebrospinal fluid to bypass an obstructed cerebral aqueduct and drain directly into the prepontine subarachnoid cisterns.

Indications & Common Reasons for Surgery

This advanced neurosurgical intervention is recommended for patients diagnosed with:

• Non-communicating (obstructive) hydrocephalus due to congenital or acquired aqueductal stenosis.
• Posterior fossa tumors or tectal plate gliomas obstructing CSF outflow.
• Malfunctioning or infected VP shunts in patients with favorable anatomical criteria (ETV Success Score).

Surgical Techniques & Precision Modalities

Performed through a single precoronal burr hole using a rigid neuroendoscope; the tuber cinereum is safely perforated and dilated with a Fogarty balloon catheter under direct high-definition vision. The procedure is performed in advanced modular operating suites equipped with 3D neuronavigation, high-definition intraoperative microscopes, neuro-endoscopy, and real-time electrophysiological monitoring to preserve vital neurological functions.

Postoperative Care & Recovery Timeline

Provides natural physiological internal CSF circulation without the lifelong risks of hardware dependency, shunt blockages, or mechanical failure. Patients benefit from specialized neuro-intensive care, personalized neuro-rehabilitation, and multidisciplinary follow-up to support optimal long-term functional outcomes.

Key Clinical Benefits

• Targeted, maximal safe anatomical correction and pathology excision.
• Protection of eloquent brain areas and essential cranial nerve pathways.
• Significant alleviation of neurological symptoms and prevention of secondary brain injury.
• Accelerated recovery supported by modern microsurgical and minimally invasive techniques.
