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.
