Answer

Without treatment, one half of patients with deep venous thrombosis (DVT) have a recurrent, symptomatic venous thromboembolism (VTE) event within 3 months. After anticoagulation for an unprovoked VTE event is discontinued, the incidence is 5-15% per year. Presentations are similar, with pain and edema. However, the diagnosis may be difficult (ie, differentiating acute from chronic thrombus). Recurrence increases the risk of postthrombotic syndrome (PTS).
