Correlation between placental histopathology and fetal/neonatal outcome: chorioamnionitis and funisitis are associated to intraventricular haemorrage and retinopathy of prematurity in preterm newborns



Correlation between placental histopathology and fetal/neonatal outcome: chorioamnionitis and funisitis are associated to intraventricular haemorrage and retinopathy of prematurity in preterm newborns



Gynecological Endocrinology 27(5): 319-323



Placental anatomopathologic lesions are usually associated with pregnancy complications and neonatal impaired outcome. We included in our study 122 patients with gestational age of 26-35 weeks. From the analysis of three pathological aspects (chorioamnionitis, funisitis and chronic hypoxia), a score was assigned to each lesion depending on the severity of the alteration, to establish a correlation with an impaired neonatal outcome in preterm newborns. We found a correlation between chronic hypoxia and preeclampsia, intrauterine growth restriction and/or small-for-gestational age status at birth. Our results also showed the strong association of fetal placental inflammatory status (chorioamnionitis and funisitis) with premature rupture of membranes, very low birth weight, birth at/before 32 gestational weeks, late-onset sepsis, patent duct arteriosus, intraventricular haemorrhage (IVH) and retinopathy of prematurity (ROP). We confirm that placental lesions are associated with impaired pregnancy and neonatal outcome. During pregnancy it may be useful to identify some markers of inflammatory status and chronic hypoxia for an early diagnosis and a detailed monitoring of pregnancy course. Placental pathological analysis is very important to predict the risk of developing serious complications of preterm birth as ROP and IVH.
