Abstract
Objectives: We aimed to compare perinatal outcomes of oligohydramnios or fetal growth restriction with normal amniotic fluid index and fetal growth in preeclampsia and to compare the outcomes of only oligohydramnios, only fetal growth restriction and oligohydramnios with fetal growth restriction preeclamptic groups.
Material and methods: A total of 743 preeclamptic patients were evaluated between June 2016 and 2020. Patients were divided into two groups: preeclampsia with oligohydramnios or fetal growth restriction (n = 237) and preeclampsia with normal amniotic fluid index and fetal growth (n = 506). Then, the first group was divided subgroups as only oligohydramnios (n = 55), only fetal growth restriction (n = 125) and oligohydramnios with fetal growth restriction (n = 57). Demographic characteristics and perinatal outcomes were recorded.
Results: Gestational age at delivery (p < 0.001), birth weight (p < 0.001), Apgar scores (p < 0.001) and eclampsia (p < 0.001) were lower whereas impaired doppler findings (p < 0.001), cesarean rates (p < 0.001), preterm delivery (p < 0.001), abruptio placenta (p < 0.001), acute fetal distress (p < 0.001), RDS (p < 0.001), NICU requirement (p < 0.001) and neonatal death (p < 0.001) were higher in oligohydramnios or fetal growth restriction preeclamptic group. In subgroup analysis, there were differences between three groups according to the gestational age (p < 0.001), cesarean rates (p = 0.002), preterm delivery (p < 0.001), intensive care unit requirement (p = 0.039), birth weight (p < 0.001), Apgar scores (p < 0.001), RDS (p < 0.001) and NICU requirement (p < 0.001). In pairwise comparison, there was significant difference between only oligohydramnios and only fetal growth restriction group and between only oligohydramnios and oligohydramnios with fetal growth restriction group according to birth weight, Apgar scores, preterm delivery and cesarean rates, presence of RDS, maternal and neonatal intensive care unit requirement. No significant difference was detected between only fetal growth restriction group and oligohydramnios with fetal growth restriction group in terms of all parameters.
Conclusions: We suggest that patients with only oligohydramniosis have more favorable pregnancy outcomes than pregnants with only fetal growth restriction and coexistence of two conditions in preeclamptic patients. We claim that it could be appropriate to recommend close monitorization in preeclamptic patients with only fetal growth restriction and oligohydramniosis and fetal growth restriction.
