Update on diagnosis and anticoagulant therapy for venous thromboembolism

Venous thromboembolism (VTE) continues to be a common medical problem requiring the need for rapid treatment with anticoagulant therapy. Until the recent availability of the direct oral anticoagulants for treatment of VTE, the option for oral anticoagulation was limited to warfarin therapy. The addition of these new medications has been welcomed, but has led to added complexities in deciding the most appropriate agent for each patient based on individual risk factors. Furthermore, there are several circumstances where optimal duration of therapy is not well established. This article will focus on the diagnosis of VTE, the choice of anticoagulant and treatment duration.
