title: Lepirudin for treatment of acute thrombosis during pregnancy.
abstract: BACKGROUND
  Thromboprophylaxis during pregnancy can be challenging when heparin is contraindicated. Limited data exist regarding alternative anticoagulants in the setting of pregnancy.
  
  
  METHODS
  We present a patient with antiphospholipid syndrome who developed heparin-induced thrombosis in the third trimester of pregnancy. She was treated with therapeutic doses of intravenous lepirudin until delivery. Induction of labor, regional anesthesia, and forceps-assisted vaginal delivery were performed with no fetal, neonatal, or maternal complications. Postpartum, the patient was transitioned to warfarin therapy, and at 6 weeks postdelivery neither the patient nor her infant had developed any new problems.
  
  
  CONCLUSIONS
  Intravenous lepirudin use at therapeutic doses in late gestation as an alternative to heparin was accomplished with minimal maternal and fetal morbidity.
