=====Shunt revision=====
There is elevated risk of [[shunt infection]] associated with shunt revisions observed in clinical practice. To reduce risk of [[infection]] risk, further work should optimize revision procedures

The decision to admit a [[shunt]]-treated patient from the emergency department for symptoms related to [[idiopathic intracranial hypertension]] (IIH) is challenging. Knowledge of factors associated with the need for admission and/or shunt revision is required. In a study, factors such as male sex, younger age at presentation, lower number of prior emergency department visits, and performance of a diagnostic LP were independent predictors of admission. In addition, [[papilledema]] was strongly predictive of the need for [[shunt revision]], highlighting the importance of an ophthalmological examination for shunt-treated adults with IIH who present to the emergency department
