    Abstract:
    BACKGROUND: Endovascular treatment of ruptured intracranial aneurysms (rIAs) accompanied by intracerebral hematoma (ICH) can be challenging because the ICH can be enlarged due to intraoperative anticoagulation during the endovascular procedure. This retrospective study aimed to compare the outcomes of aneurysmal subarachnoid hemorrhage with and without ICH treated by endovascular procedures. METHODS: We reviewed 62 patients who underwent endovascular treatment of rIAs between January 2015 and April 2023. The patients were divided into 2 groups: those with ICH (group H; n = 13) and those without ICH (group N; n = 49). The patient demographics, aneurysm characteristics, World Federation of Neurosurgical Societies (WFNS) grade, complications (e.g., symptomatic vasospasm, hydrocephalus), and outcomes were assessed stratified by the presence of ICH. In group H, age, sex, complications, WFNS grade, and hematoma volume were also analyzed in relation to the outcomes at discharge. RESULTS: None of these patients required removal of ICH after endovascular treatment of the rIA. We found no significant differences in patient characteristics, aneurysm morphologies, WFNS grade, or overall outcomes between the 2 groups. In contrast, only a poor WFNS grade was significantly associated with poor outcomes (modified Rankin scale score ≥3) in group H (P = 0.04), and the ICH volume was not significantly different between those with good (6.2 ± 5.8 mL) and poor (14.6 ± 10.4 mL) outcomes in group H (P = 0.20). CONCLUSIONS: Endovascular treatment without hematoma evacuation did not adversely affect the outcomes of rIAs with ICH when the clinical condition and aneurysm morphology permitted. Surgical invasion might be avoidable with this less-invasive strategy without worsening the outcomes.
