Purpose
Preeclampsia (PE) complicates 2-8% of pregnancies. It is associated with an increased risk of adverse maternal (death, eclampsia, abruptio placenta, HELLP syndrome) and perinatal (perinatal death, growth restriction, prematurity) outcomes. The only definite treatment of PE remains pregnancy termination. Therefore, prevention of PE remains an important challenge. Low dose aspirin may be used in the prevention of PE, particularly in women who had a severe preeclampsia before 34 weeks. Its efficiency, however, is very weak. Recently, it has been suggested that low molecular weight heparin might be useful in the prevention of PE.
The aim of this study is to analyze the usefulness of the enoxaparin 4000 UI/day in the prevention of a composite maternal or perinatal morbidity (occurrence of one of the following events: maternal death, PE, fetal growth retardation, abruptio placenta, perinatal death) in women who previously had a severe preeclampsia at less than 34 weeks' gestation. To answer this question, the investigators propose to conduct a multicenter prospective randomized trial that will compare two groups in parallel: a group where women will have an association of enoxaparin 4000 U/day and aspirin 100 mg/day and another group where women would have only aspirin 100 mg/day. The number of patients needed is 255 (amendment n°2-approved 06/12/2011) .

Primary Outcome Measures:
- The primary outcome is a composite morbidity that may occur : maternal death, or perinatal death, or preeclampsia, or abruptio placenta, or fetal growth restriction. [ Time Frame: from randomization until one month after the delivery ]
Secondary Outcome Measures:
- Recurrence of preeclampsia alone [ Time Frame: from randomization until one month after the delivery ]
- Recurrence of severe preeclampsia [ Time Frame: from randomization until one month after the delivery ]
- Fetal growth restriction alone [ Time Frame: from randomization until one month after the delivery ]
- Severe fetal growth restriction (< 5th percentile) [ Time Frame: from randomization until one month after the delivery ]
- Perinatal death alone [ Time Frame: from randomization until one month after the delivery ]
- Neonatal death [ Time Frame: from randomization until one month after the delivery ]
- Abruption alone [ Time Frame: from randomization until one month after the delivery ]
- Maternal death [ Time Frame: from randomization until one month after the delivery ]
- Fetal loss (10-21 weeks) [ Time Frame: from randomization until one month after the delivery ]
- Fetal death [ Time Frame: from 15 weeks to delivery ]
- Recurrence of preeclampsia controlled for thrombophilia analysis (polymorphism of factor V Leiden, prothrombin G20210A gene polymorphism) [ Time Frame: from randomization until one month after the delivery ]
- Recurrence of preeclampsia controlled for angiogenic factors (free VEGF and PlGF, sFlt1, sEng) [ Time Frame: from randomization until one month after the delivery ]
- Neonatal morbidity (NICU transfer, length of hospitalization, mechanical ventilation > 24 hours, respiratory distress syndrome, necrotizing enterocolitis, periventricular leucomalacia, bronchopulmonary dysplasia, intraventricular hemorrhage grade III-IV) [ Time Frame: from randomization until one month after the delivery ]
- Enoxaparin toxicity: hemorrhage, skin reaction, thrombocytopenia (<100000/µL) related to heparin [ Time Frame: from randomization until one month after the delivery ]
- Bone fracture [ Time Frame: from randomization until one month after the delivery ]
