    Objective High-grade gliomas are associated with venous thromboembolism (VTE). This retrospective study with a parallel cohort design investigated influence of continuing prophylactic anticoagulation after discharge on rate of VTE and intracranial hemorrhage (ICH) in patients operated on for high-grade glioma. Methods Consecutive adult patients who underwent subtotal or gross total resection for high-grade glioma at a single institution were included. Multivariable logistic regression analysis was used to investigate the association between duration of thromboprophylaxis (dalteparin administered 21 days vs. 0–7 days) and occurrence of VTE and ICH within 21 or 90 days after surgery, corrected for known risk factors. Results Of 301 included patients, 166 received short-term thromboprophylaxis, and 135 received prolonged thromboprophylaxis. In multivariable analysis, prolonged thromboprophylaxis was not significantly associated with occurrence of VTE within 21 days (3.0% vs. 1.2%; P = 0.24) or 90 days (8.9% vs. 4.8%; P = 0.09) after surgery; however, prolonged prophylaxis was associated with occurrence of ICH (5.9% vs. 0.6%; P = 0.03). Additionally, immobility ( P = 0.03) and high body mass index ( P = 0.02) were associated with occurrence of VTE. Conclusions Prophylactic anticoagulation for 21 days postoperatively was not associated with a decreased rate of VTE compared with thromboprophylaxis until discharge. ICH was more common with prolonged thromboprophylaxis. These results provide insufficient evidence to extend duration of prophylaxis beyond hospitalization. Large-scale randomized prospective studies are needed to clarify safety, efficacy, and optimal timing of postoperative thromboprophylaxis in patients with high-grade glioma. Highlights Continuing anticoagulation after discharge was not associated with a lower VTE rate. Prolonged thromboprophylaxis was associated with a higher ICH rate. Immobility and obesity were identified as independent predictors of VTE.
