Effect of anticoagulant therapy for 6 weeks vs 3 months on recurrence and bleeding events in patients younger than 21 years of age with provoked venous thromboembolism. The Kids-DOTT randomized clinical trial.

Some 417 patients under 21 years of age were included. Rates of recurrent venous thromboembolism were similarly low after both treatments: 0.66 per cent after six weeks of versus 0.7 per cent after three months of anticoagulation.

Comment: Very low recurrence rates, but six weeks of anticoagulation seems reasonable.
