A graphical abstract of some of the current notions of PEVs in different obstetric pathologies. As represented, the role of PEVs remains to be further explored in the field of fetal growth restriction, infections and preterm birth. However, some initial results are starting to arise in these conditions, aiding to improve our knowledge of these obstetric complications. Due to the relevance of PEVs in many physiological and pathological processes, we encourage for future studies in these areas.
