ABSTRACT
Introduction:
Hypertensive disorders of pregnancy continue to pose the most important risks for adverse maternal and neonatal outcome. Among histological findings, decidual artery disease is one of the most common, one that has both good reproducibility among observers and whose abnormal vascular remodeling is the sole aspect of preeclampsia pathophysiology on which experts agree. Nevertheless, some aspects of arterial remodeling alterations are still under investigation.Methods:
We selected 720 routine and consecutive placenta case studies, concordant with the Amsterdam consensus. From these studies, we collected maternal and neonatal clinical data and specific placental findings on spiral artery abnormalities. We took into account all criteria for decidual arteriopathy. Two hundred and fifteen (215) cases out of this population presented hypertensive disorders of pregnancy. Additional to expected arterial findings, we noted frequent persistent parietal trophoblast lining.Results:
A large proportion of our population developed hypertensive disorders of pregnancy (30%). Among the histologic findings reported for preeclampsia, we paid particular attention to spiral artery abnormalities, and this interpretive analysis revealed high frequency of arterial remodeling abnormalities. We examined two additional aspects in our routineanalysis:
first, the novel one of parietal trophoblast persistence, and second, the established problem of associated acute inflammation, as a possible pitfall.Conclusion:
In order to better understood, spiral maternal artery remodeling merits further study. The abnormalities in this process provide an objective tool in the study and diagnosis of important pregnancy complications; furthermore, abnormal remodeling is an expression of early pregnancy alteration, and subsequently related to preeclampsia etiology.Palabras clave
