Patients with obstructive hydrocephalus can be treated with a minimally invasive endoscopic procedure that bypasses the blockage, restoring appropriate cerebrospinal fluid (CSF) flow.
This procedure helps to avoid placing a ventriculoperitoneal shunt and has less chance of overdrainage complications. Endoscopic third ventriculostomy (ETV) offers a durable surgical option for patients. This internal bypass can, in a minority of patients, close or be ineffective, ultimately requiring a shunt. Overall, this procedure is well tolerated, though complications including infection and bleeding can occur.
