Cerebrospinal fluid shunting, including ventriculo-abdominal/atrial and lumbar-abdominal shunts, is the only treatment available for idiopathic normal pressure hydrocephalus (iNPH). Hybrid valves that combine a programmable pressure valve and an antisiphon device are being widely used for treatment of iNPH, which has significantly minimized surgical complications, such as shunt revision and subdural hematomas associated with overdrainage. Development of novel technologies that can maintain a more physiological intracranial environment after shunting presents a challenge for future research.
