Factors that Affect Postoperative Hydrocephalus Development in Aneurysmal Subarachnoid Hemorrhage: A Clinical Study

Abstract

Aim: Factors affecting the development of postoperative hydrocephalus patients who underwent surgery after aneurysmal subarachnoid hemorrhage were retrospectively assessed.

Material and methods: 201 cases, who underwent aneurysm surgery in our clinic after subarachnoid hemorrhage between 2008 and 2013, were retrospectively assessed. Twenty-one cases with hydrocephalus development were retrospectively examined according to their age, gender, history (hypertension, alcohol, and smoking), blood type, the number and size of aneurysms, aneurysm localization, the presence of ventricular hemorrhage, baseline-final neurological diagnosis, Fisher grading system, history of vasospasm and meningitis. The initial neurological course and Hunt-Hess, and also final neurological course of the patients were evaluated according to World Federation of Neurosurgical Societies (WFNS) Grading Scale.

Results: Age, history of hypertension, aneurysm localization, Hunt-Hess grading, vasospasm, meningitis and Glasgow Outcome Scale (GOS) are determinative factors in hydrocephalus development due to subarachnoid hemorrhage. It was detected that gender, alcohol and tobacco use, blood group, the size and the number of aneurysm, the presence of intraventricular hemorrhage and Fisher grading were not the determinative factors in the patients.

Conclusion: In patients who underwent surgery for subarachnoid hemorrhage, risk factors for postoperative hydrocephalus should be determined and the patients with these risk factors should be closely monitored.
