Management of hydrocephalus with programmable valves after traumatic brain injury and subarachnoid hemorrhage

Programmable shunt valves are a recent technological advance that enhance the management of most patients with hydrocephalus secondary to subarachnoid hemorrhage or traumatic brain injury. An improved understanding of the intracranial pressure dynamics occurring both before and after a cerebrospinal fluid diversionary shunt has provided a more scientific basis for the application of these valves.
