Abstract: Background: Postoperative hemorrhage (POH) is a rare yet serious complication of cranial surgery, potentially resulting in extended hospitalization, neurological impairment, or death. Existing predictive models often encompass diverse cranial pathologies, despite differing mechanisms of POH depending on the underlying condition. There is a lack of large-scale investigations focusing exclusively on POH following surgery for intracranial tumors. This study aimed to assess demographic variables—age, sex, and blood type—and pre-existing medical conditions as potential risk factors for POH in this specific context. Methods: A retrospective review was conducted on medical records of 1862 adult patients who underwent primary surgical resection of intracranial tumors. Univariate and multivariate analyses were applied to identify associations between POH and demographic or clinical characteristics. Results: POH, defined as postoperative hematoma necessitating surgical evacuation, was observed in 31 patients (1.7%). Univariate analysis revealed no statistically significant correlation between POH and demographic factors (age, sex) or pre-existing conditions such as hypertension, diabetes mellitus, cardiac disease, or liver dysfunction. Conclusions: The study found no evidence that demographic variables or pre-existing medical conditions independently contribute to the risk of POH following intracranial tumor resection in adults.
