Venous thromboembolism (VTE) is a common complication in patients with brain tumors. The management of acute VTE is particularly challenging due to an elevated risk of intracranial hemorrhage (ICH). Risk of developing ICH on anticoagulation is influenced by a number of factors including tumor type, recent surgery, concomitant medications, platelet counts, and radiographic features. In patients with a heightened risk for ICH, the benefits of anticoagulation need to be balanced against a likelihood of developing major hemorrhagic complications. Management decisions include whether to administer anticoagulation, at what dose, placement of an inferior vena cava filter, monitoring for development of hemorrhage or progressive thrombus, and escalation of anticoagulant dose. This article discusses the complexities of treating acute VTE in patients with brain tumors and outlines treatment algorithms based on the presence or absence of ICH at the time of VTE diagnosis. Through case-based scenarios, we illustrate our approach to anticoagulation, emphasizing individualized risk assessments and evidence-based practices to optimize treatment outcomes while minimizing the risks of hemorrhagic events in patients with brain tumors.
