Anticoagulant therapy was administered to 15 pregnant women whose prior pregnancies had been complicated by extensive placental infarctions, intrauterine growth retardation of the fetus, and/or stillbirths. With anticoagulant therapy, 15 live infants were born, none growth retarded, and no severe infarction of placentas was observed. Therapy resulted in no adverse reactions in either the mothers or the neonates.
