Simple Summary: Meningiomas are most commonly benign intracranial tumors, and surgical resection represents the treatment modality of choice. However, especially for patients of higher age and with increasing comorbidities, brain surgery might be accompanied by the need for postoperative prolonged intensive care, which might impair intended operative benefit. In the present study, we therefore analyzed prolonged mechanical ventilation (PMV) as an indicator variable for such intensive care treatment with regard to potential effects on mortality after meningioma resection in patients aged 70 years and older. We found that patients with postoperative PMV exhibited a profoundly increased probability to die within 1 year after surgery. Based on these findings, we identified risk factors for postoperative PMV occurrence and developed an easy-to-use score which allows us to estimate the risk of PMV occurrence preliminary to the surgical resection. We believe that this score might help to more sufficiently guide patients in the course of risk–benefit assessment and preoperative counseling. Indication for surgical treatment in patients with intracranial meningioma must include both clinical aspects and an individual risk–benefit stratification, especially in geriatric patients. Prolonged mechanical ventilation (PMV) has not been investigated for its potential effects in patients with meningioma. We therefore analyzed the impact of PMV on mortality in geriatric patients who had undergone meningioma resection. Between 2009 and 2019, 261 patients aged ≥ 70 years were surgically treated for intracranial meningioma at our institution. PMV was defined as postoperative invasive ventilation of >7 days. Postoperative PMV was present in 17 of 261 geriatric meningioma patients (7%). Twenty-five geriatric patients (10%) died within 1 year after surgery. A scoring system ("ACKT") based on the variables of age, preoperative C-reactive protein (CRP) value, Karnofsky performance scale and tumor size supports prediction of postoperative PMV (sensitivity 73%, specificity 84%). PMV is significantly associated with increased mortality after surgical treatment of meningiomas in geriatric patients. Furthermore, we suggest a novel score ("ACKT") to preoperatively estimate the risk of PMV occurrence, which might help to guide future risk–benefit assessment and patient counseling in the geriatric meningioma population.
