To study the correlation between severe oligohydramnios with perinatal outcome along with histopathology of placenta

Abstract

The aim: To study the correlation between severe oligohydramnios with perinatal outcome and the placenta's histopathology.
 Materials and methods: comprised of 100 patients with oligohydramnios diagnosed after 28 weeks of gestation, admitted on an emergency basis, both booked / unbooked, who were willing to cooperate, were chosen. All patients with oligohydramnios (AFI<5 %) were included in the study.
 Results: 3 cases came with intra-uterine death. All three were totally unbooked cases. 2 preterm babies died neonatal intensive care unit after 4 days due to meconium aspiration syndrome. Thus the perinatal mortality was 5 %. 44 % of neonates required admission into the neonatal intensive care unit. In our study, it was found that neonatal mortality and morbidity increased significantly when oligohydramnios was associated with complications like IUGR and pregnancy-induced hypertension in mothers. All the cases associated with these histopathological changes had adverse perinatal outcomes. Hence estimation of the amount of liquor is important in the antenatal period because oligohydramnios gives insight into the associated maternal complications or fetal anomalies and has a significant bearing on the perinatal outcome. The placental examination will illuminate all the conditions affecting the perinatal outcome. Without associated complications, oligohydramnios does not have adverse perinatal outcomes.
 Conclusions: Thus, in cases of oligohydramnios with no associated complications, expectant management can be tried for a better fetal outcome. Only oligohydramnios may be the first sign of placental insufficiency and an independent manifestation of the placental-related complications spectrum.
