Material and methods: We performed a PubMed search. We included randomized controlled trials, systematic reviews and meta-analyses published between 2003 and 2013 and written in English. The main outcome of interest was preeclampsia. Results: The search identified 174 articles, but only 13 were selected. The control group consisted of patients receiving placebo or no treatment. Aspirin doses were between 40 and 160 mg/day. Aspirin was administered before or after 20 weeks of pregnancy. The effect of aspirin was compared, depending on whether the women had risk factors or if they developed severe preeclampsia or preterm preeclampsia. Conclusion: We recommend the use of low-dose aspirin in high risk pregnancies before 16 weeks of pregnancy.
