Premature placental aging and perinatal complications

Abstract

Objective: To determine by ultrasound the frequency and type of perinatal complications in pregnant women with grade 3 placenta before 35 weeks. Methods: Analytical, observational, retrospective, cross-sectional, retrospective study that included all pregnant women diagnosed with grade 3 placenta by ultrasound between 23 and before 35 weeks. The pregnant women did not present comorbidity, multiple pregnancy or fetuses with malformations. Results: A total of 235 pregnant women with grade 3 placenta by ultrasound were found, of which 119 were randomly sampled. The frequency of perinatal complications in pregnant women with grade 3 placenta by ultrasound before 35 weeks was 29.4%, the most frequent being low birth weight (18.5%) and respiratory distress syndrome (17.6%). The chi-square test resulted 0.000 for gestational age at birth and 0.015 for gestational age at diagnosis, with significance level p < 0.05 of association of complications in pregnant women with placenta grade 3 before 35 weeks. Conclusion: Ultrasound diagnosis of early placental aging was associated with a high frequency of perinatal complications. Key words: Placenta, Ultrasonography, Pregnancy complications.
