ObjectiveThis study aims to present the clinical characteristics and surgical treatment in patients with intracranial hemangioblastomas and to investigate risk factors for postoperative functional outcomes.MethodsPatients with intracranial hemangioblastomas who received surgical treatment in our institute between 2011 and 2020 were included. We retrospectively reviewed and analyzed the clinical characteristics, surgical treatment, and postoperative functional status. Risk factors for postoperative functional outcomes were further analyzed using univariate and multivariate analysis.ResultsWe identified 48 patients with 82 intracranial hemangioblastomas resected in this study. There were 22 females and 26 males, and the mean age was 39.3 ± 15.3 years. Total resection was achieved in all the cases. After primary surgery, immediate functional status was improved in 20 patients (41.7%), stable in 9 patients (18.8%), and worsened in 19 patients (39.6%). Forty-two patients (89.4%) had favorable functional status (Karnofsky Performance Scale ≥80) at long-term follow-up. Through univariate and multivariate analysis, body mass index, number of resected tumors per operation, and intraoperative blood loss were independent risk factors for the immediate functional outcome (P = 0.006, P = 0.023, P = 0.038, respectively). Preoperative hydrocephalus was significantly associated with unfavorable long-term functional status (P = 0.047).ConclusionsGenerally, patients can benefit from surgical removal of intracranial hemangioblastomas with favorable functional outcomes. Body mass index, number of resected tumors per operation, and intraoperative blood loss can be used as risk factors for immediate functional outcomes after surgery, and preoperative hydrocephalus for long-term functional status.Copyright © 2022 Elsevier Inc.
