Burden to Patients: VTE is associated with complications including recurrence of DVT or PE, chronic thromboembolic pulmonary hypertension, death, or the subsequent development of post-thrombotic syndrome. The risk of VTE recurrence is greatest within 6-12 months after the first event and continues for at least 10 years,17 and is a risk factor for death after PE.18 The post-thrombotic syndrome can have devastating effects on the patients' quality of life and is associated with venous hypertension that may cause pain, edema, skin changes, varicose veins, and skin ulcers. Valve dysfunction, which can lead to venous hypertension, is most often caused by a previous DVT.19 The cumulative incidence of the development of postthrombotic syndrome after a VTE event is high: 17% at one year, 23% at 2 years, and 29% at 8 years, with 30% of these cases classified as severe.20
