Treatment of hydrocephalus is usually surgical, which is a relatively simple procedure and is not major surgery. If hydrocephalus is significant and the patient has symptoms such as headache, vomiting, decreased muscle strength, incontinence, mental abnormalities, dementia, etc., surgical procedures are required, usually a ventriculoperitoneal shunt or a fistula at the base of the third ventricle. Both of these surgical procedures are minimally invasive, with minimal surgical trauma and quick recovery, and do not cause new complications. A ventriculoperitoneal shunt involves only drilling a hole in the head and inserting a ventricular drainage tube through which cerebrospinal fluid is continuously introduced into the abdominal cavity for absorption. Third ventricular base fistulotomy requires only drilling a hole in the head and inserting a neuroendoscope into the third ventricle to perform a fistula at the base of the third ventricle, which allows hydrocephalus to participate in the circulation of cerebrospinal fluid, thus relieving hydrocephalus. Both procedures are not major surgeries and are moderate.
