Management of thrombosis in antiphospholipid antibody syndrome.

Antiphospholipid antibody positive patients are at risk for venous and arterial thrombosis. The risk of recurrent thromboembolism is high. Although the standard of care is high-intensity warfarin after a thromboembolic event, some studies indicate that this degree of anticoagulation is not needed. There is an urgent need of clinical trials to address management of thrombosis in antiphospholipid syndrome.
