Answer

Long-term therapy with LMWH has been shown to be as effective as warfarin in the treatment of venous thrombosis, except in those patients with a concurrent malignancy. In this subgroup, LMWH was shown to be more effective than oral therapy. [138, 139] Initial studies have also shown LMWH to be effective in pregnant patients, but long-term, large randomized trials have yet to be completed. [140]
