Placenta with Pre-Eclampsia: A Systematic Review

The objective of this study was to carry out a systematic review that the amount of anatomopathological alterations in placentas from women who would develop PE would be higher compared to placentas from pregnant women without preeclampsia. In methods, for this systematic review, the keywords (“preeclampsia” and “placenta”) were used, four databases were searched: SciELO, Lilacs, Google Scholar and Embase. In the results obtained, it is observed that, of the Of the 86 registries identified, 6 were eligible. Other findings that, due to their frequency and maternal and fetal adverse outcomes, are very important: microscopic and macroscopic alterations, firstly, excess fibrin, secondly, abundant syncytial knots and, secondly, abundant syncytial knots. Thirdly, heart attacks. Within the macroscopic alterations of the placenta we found: low-weight placentas and finally, the evaluation of the methodological certainty of the six articles that entered the SR; they reached a score of >70%, classifying them as “sufficiently reported” articles. In conclusion, we say that the anatomopathological alterations that occur in the placenta lead to a dysfunctional, hypoxic and ischemic placenta, causing PE and maternal, fetal and neonatal complications.
