What methods are used to treat aSAH-associated hydrocephalus?
Acute hydrocephalus associated with aSAH is usually managed by external ventricular drainage (EVD) or lumbar drainage. EVD for patients with aSAH-associated hydrocephalus is generally associated with neurological improvement. Lumbar drainage for the treatment of aSAH-associated hydrocephalus has been reported to be safe, but it has only been examined in retrospective series. Chronic hydrocephalus associated with aSAH is usually treated with ventricular shunt placement.
