    Abstract:
    OBJECTIVE: We investigated the predictors and outcomes of aneurysmal subarachnoid hemorrhage in patients with shunt-dependent hydrocephalus and make a preliminary inquiry into the relationship between the two. METHODS: A consecutive cohort of 202 patients was evaluated, which included 40 shunt-dependent hydrocephalus patients. The basic characteristics on admission, complications of hemorrhage, management before onset of chronic hydrocephalus, and outcomes of shunting were established. The Glasgow Outcome Scale score was used to evaluate the recovery of patients with a ventriculoperitoneal (V-P) shunt. Furthermore, relevant statistical analyses were presented to identify the significance of risk factors and prognostic factors associated with shunt-dependent hydrocephalus. RESULTS: From among 202 patients, 40 (19.8%) developed shunt-dependent hydrocephalus, and 26 (65.0%) of these 40 improved after undergoing a V-P shunt. In the univariate analysis, age, preexisting hypertension, Glasgow Coma Scale score, Hunt-Hess grade, modified Fisher grade, posterior circulation, rebleeding, acute hydrocephalus, intraventricular hemorrhage, vasospasm, nosocomial meningitis, neurosurgical clipping, decompressive craniectomy, external ventricular drainage (EVD), and duration of EVD were significantly related to shunt-dependent hydrocephalus; moreover, age, preexisting hypertension, posterior circulation, acute hydrocephalus, intraventricular hemorrhage, and decompressive craniectomy were independent predictors. Similarly, age, Hunt-Hess grade, Glasgow Coma Scale score, nosocomial meningitis, and duration of EVD could be the prognosticators of a V-P shunt. CONCLUSIONS: Patients who were older, with worse mental function status on admission, nosocomial meningitis, and longer duration of EVD, are susceptible to shunt-dependent hydrocephalus because of ruptured intracranial aneurysm and also have unfavorable outcomes after a V-P shunt. Timely and appropriate treatment can benefit such patients in recovery.
