    Abstract:
    Intracerebral hematoma (ICH) as a result of ruptured of intracranial aneurysms often arises in patients with subarachnoid hemorrhage. Few studies focused on risk factors for ICH and not the impact of residual hematoma after evacuation on the outcomes of the patients. Therefore, 2 questions need to be answered: does residual hematoma after evacuation have impact on the outcome of patients who present with ICH as a result of ruptured intracranial aneurysms? Is radical pursuit of the hematoma necessary? The study was a single-center longitudinal observational type. Data of 2044 consecutive patients with subarachnoid hemorrhage from January 2009 to December 2019 were reviewed. ICHs were established and the locations of aneurysms as well as hematoma volumes were measured by computed tomographic scan before aneurysm occlusion. Only patients who received aneurysm clipping were included. Patients were stratified into hematoma evacuation without residuals versus residual hematoma after evaluation groups, and outcome was assessed according to the modified Rankin Scale (mRS) at 6 months. Out of the 1365 patients who received clipping, 476 patients presented in poor grade, whereas 889 patients' good grade. Our mRS scores revealed that patients who attained hematoma evacuation without residuals in the good-grade category attained better functional outcome than those with residual hematoma after evacuation. Contrarily, our mRS scores did not establish any significant difference in outcome between the poor-grade patients with hematoma evacuation without residuals and patients with residual hematoma after evacuation. Furthermore, our logistic regression model showed that advance age, poor Hunt-Hess grade, and vascular injury due to surgery were contributing factors for poor outcome of patients with ICH. Our data suggested that aggressive hematoma evacuation may not benefit the poor-grade patients. Majority of poor outcomes were due to surgical complications which were vascular related as a result of excessive pursuit of ICH.
