Endoscopic Third Ventriculostomy (ETV)

Endoscopic third ventriculostomy is an alternative surgical procedure that creates a bypass for the cerebrospinal fluid in the head that eliminates the need for a shunt. It is helpful only to people with hydrocephalus that is caused by a blockage of the flow of cerebrospinal fluid.

Endoscopic means that the surgery is performed with the use of an endoscope. An endoscope is a thin tube that has a strong light, a powerful magnifying lens and a passage through which tiny instruments are passed.
