porvoked VTE ->吃3個月即可 最近有一位病人,CVA長期臥床 約一年前hip fracture, 三個月後DVT(provoked VTE) 在長庚吃coumadin吃到現在 -> 應該不用吃了 Summary and Comment Minimizing Recurrence of VTE Initial presentation of venous thromboembolism and duration of previous anticoagulation were associated with risk for recurrence. How does clinical presentation of venous thromboembolism (VTE) and duration of anticoagulation affect risk for recurrent VTE after anticoagulation is stopped? In this pooled analysis of data from seven randomized trials that involved 2925 participants, investigators addressed this question. Twenty percent of the patients had isolated distal deep venous thrombosis (DVT), 52% had proximal DVT, and 29% had pulmonary embolism (PE). VTE was provoked by a temporary risk factor (e.g., immobilization) in 40%. During mean follow-up of 1.4 years, 312 episodes of recurrent VTE occurred. Risk for recurrent VTE in patients with isolated distal DVT was about half that of patients with proximal DVT
