Demographic and morphometric characterization of the Gestational Hypertensives Syndromes

Abstract

The hypertensive disorders of pregnancy (SHG) have variable intensity according to their type. This study aimed to describe the demographic characteristics and maternal-fetal morphometric changes of placenta in different types of SHG by retrospective analysis of medical records of hypertensive patients with placentas evaluated morphologically, processed for immunohistochemistry using monoclonal antibody anti-human CD31 and analyzed morphometrically . The results showed that among the SHG, the groups with chronic hypertension (CH) and Pre-eclampsia superimposed on chronic hypertension (PSHC) showed higher maternal age (p = 0017). The frequency of the SHG was higher among multiparous. Lower gestational age, lower Apgar score and placental weights lower than expected for the population (p <0.05) were observed in cases with pre-eclampsia (PE) and PSHC. There was no difference in the number of vessels of placental stem villi. In the others, there was an increase in cases with PE and gestational hypertension (HGE) and reduction in cases with PSHC. The importance of the study is to describe the demographic and morphological SHG to improve the obstetric care and understanding of different types of SHG. The severity of symptoms of SHG is related to higher maternal and fetal complications and changes in placental vascular patern
