[Successful prophylaxis in a pregnancy with thrombophilic states].

It has been observed that the presence of antiphospholipid antibodies (aPL) is associated with a high incidence of fetal loss and this is thought to--a result from the vasculitis of placental circulation and subsequent thrombosis. A 38-year-old woman with second fetal loss had received oral anticoagulant after pulmonary embolism. APL were examined--anticardiolipin antibodies (aCA) were found. The third pregnancy was established and sintrom was stopped and replaced by fraxiparine 0.3 ml/24 h up to the end of the pregnancy even 20 days after delivery of a healthy baby.
