Risk Factors for Development of Chronic Hydrocephalus Following Aneurysmal Subarachnoidal Hemorrhage

ABSTRACT

OBJECTIVE: Chronic hydrocephalus is a well known sequelae of an aneurysmal subarachnoid hemorrhage (SAH). However, the risk factors of the chronic hydrocephalus after SAH are still not well known. The authors design the study to focus on the incidence of chronic hydrocephalus, causal relationship between the development of chronic hydrocephalus and SAH. METHODS: The analysis of 105 consecutive patients of aneurysmal SAH was done to determine the risk factors significantly related to the development of chronic hydrocephalus needing for shunting. The risk factors for the analysis were age, sex, location of the aneurysm, Hunt-Hess grade at admission, Fisher Grade at admission CT scan, the presence of the acute hydrocephalus. RESULTS: The incidence of chronic hydrocephalus needing for shunt was 13.3%. The high Hunt-Hess grade and intraventricular hemorrhage and acute hydrocephalus were related to need for shunting of chronic hydrocephalus. CONCLUSION: We conclud that the development of chronic hydrocephalus following SAH is multifactorial. The high Hunt-Hess grade, intraventricular hemorrhage and acute hydrocephalus are related to the development of hydrocephalus.
