6 or 3 months of anticoagulant therapy did not differ for treatment failure in patients with DVT, PE, or both

摘要

Anticoagulant therapy with vitamin K antagonists is highly effective fornpreventing recurrent venous thromboembolism (VTE) but is associatednwith increased risk for bleeding. After stopping anticoagulant therapy,nabout 10% of patients have recurrent VTE. The optimal duration ofnoral anticoagulant therapy (i.e., length of treatment that minimizes risksnfor both recurrence and bleeding) is unclear.
