Hydrocephalus is seen in 10-15% of patients suffering aneurysmal subarachnoid hemorrhage. The incidence is increased where there is intraventricular hemorrhage in addition. Hydrocephalus may appear soon after the initial ictus but must also be considered as a cause of delayed recovery or neurological deterioration later in the illness. Symptomatic hydrocephalus requires intervention, which, in the first instance, will most commonly be by means of external ventricular drainage. There is some concern that the early re-bleeding rate is higher in those patients requiring drainage.
