Predicting the overall management outcome in patients with a subarachnoid hemorrhage accompanied by a massive intracerebral or full-packed intraventricular hemorrhage: a 15-year retrospective study

BACKGROUND: Patients with a subarachnoid hemorrhage (SAH) accompanied by a massive intracerebral hemorrhage (ICH) or a full-packed intraventricular hemorrhage (IVH) have poor outcomes. We evaluated the clinical factors to predict the overall outcome in such patients. METHODS: Data on nontraumatic SAH patients were collected and classified into 3 groups: the pure SAH group (SAH accompanied with neither ICH nor IVH), the ICH group (SAH accompanied with a massive ICH; hematoma 30 mL), and the IVH group (SAH and all ventricles were full-packed with hematoma). One hundred seventy-nine patients were in the ICH group and 109 in the IVH group. We evaluated clinical factors, such as the Hunt & Hess (H&H) score on admission, age, sex, history, rebleeding ratio, and the computerized tomography findings (SAH score). RESULTS: The result of multivariate logistic regression analysis of clinical variables in the ICH group, good and intermediate H&H grades, younger age (<70), no rebleeding, and lower SAH score were associated with a favorable outcome. In the result of the multivariate logistic regression analysis of clinical variables in the IVH group, only a higher SAH score was associated with an unfavorable outcome. CONCLUSIONS: In the ICH group, factors that could be used to predict a favorable outcome included good and intermediate H&H scores (1, 2, and 3) on admission, younger age (<70), and a lower SAH score. In the IVH group, the main factor that could be used to predict a favorable outcome was a lower SAH score.
