Endoscopic Third Ventriculostomy (ETV) is a minimally invasive surgical procedure used to treat conditions like hydrocephalus, where excess cerebrospinal fluid accumulates in the brain. During the procedure, a small camera and instruments are inserted through a tiny incision in the skull to create an opening in the third ventricle, allowing fluid to flow freely and reducing pressure on the brain. ETV is often preferred over traditional shunt placement because it avoids the complications associated with implanted devices. The procedure can be performed under general anesthesia and typically requires a shorter recovery time, making it a valuable option for patients, especially children.
