TO THE EDITOR:
Prandoni and colleagues (1) compared a fixed duration of anticoagulation with a flexible duration in patients with proximal DVT. Fixed-duration anticoagulation was defined according to guidelines as 3 months for secondary DVT and 6 months for unprovoked DVT, whereas flexible-duration anticoagulation was prolonged until complete recanalization occurred for up to 12 months for secondary DVT and 24 months for unprovoked DVT. The topic is interesting, especially because current guidelines (2) recommend reevaluation of patients with DVT after 3 months of anticoagulation but give no clear recommendations about how reevaluation should be performed.
