Factors Related to Chronic Hydrocephalus after Aneurismal Subarachnoid Hemorrhage

Objective To study the factors related to chronic hydrocephalus after aneurismal subarachnoid hemorrhage.Methods Clinical data of cerebral trauma patients who were treated at our hospital from Jan.2002 to Jan.2011 was retrospectively analyzed.They were divided into hydrocephalus group and nonhydrocephalus according to having hydrocephalus or not.9 indicators including gender,age,smoking history,drinking history,hypertension history,if hemorrhage into ventricle occurs,and location of the aneurysm were compared.Logistic regression model was adopted for analysis of the risk factors for chronic hydrocephalus after aneurysmal subarachnoid hemorrhage.Results The incidence of(chronic) hydrocephalus was 19.1%(129/676).Differences in age,hypertension history,intraventricular hemorrhage,aneurysm location,Fisher and Hunt-Hess grade between the patients with hydrocephalus and patients without hydrocephalus were statically significant(P 0.05).Logistic regression analysis showed that the risk factors included hypertension,presence of intraventricular hemorrhage,high Hunt-Hess grade,and high Fisher grade(P 0.05).Conclusion The incidence rate of chronic hydrocephalus is 19.1%,the patients are often combined with situations of hypertension and presence of intraventricular hemorrhage,in which cases the clinicians should take preventive measures according to the risk factors.
