Yaprak Uçar E, Uçar İlker. Evaluation of Pregnancy Outcomes of Women with Borderline Amniotic Fluid Index Measured in the Second Trimester. Adv Res Obstet Gynaecol [Internet]. 2023 Dec. 28 [cited 2024 May 18];1(2). Available from: https://arogjournal.org/index.php/arog/article/view/19


Objective: The aim of this study is to evaluate the pregnancy outcomes of pregnant women who were found to have borderline amniotic fluid index (AFI) in second trimester.

Materials and Methods: 71 patients who underwent second trimester ultrasound scan (18-24 weeks) between 1 February and 1 August 2021 at our clinic were investigated retrospectively. Patients with borderline AFI (5-8 cm) and who gave birth in the same center were selected. Pregnancy outcomes such as mode of delivery, gestational age at birth, 1st minute APGAR score and birth weights were examined. All data were obtained from the hospital database. 

Results: In the study sample, the mean age was 28.2±6.7, the mean gravida was 2±1.4 and the mean week of gestation in which AFI was measured was 22±2.5. 38.1% of the pregnancies (27 patients) resulted in cesarean section. 18.3% of births (13 patients) occurred at preterm. 16.9% of pregnancies (12 patients) resulted in low birth weight. APGAR score at 1-minute was 8 and above in all term newborns.

Conclusions: Borderline AFI detected in the second trimester is a challenging issue for the obstetricians in terms of clinical management. There is insufficient evidence in the literature regarding the effect of borderline AFI on pregnancy outcomes, and previous studies have reported controversial results. Compared to the findings of previous studies, our results support the studies reporting adverse effects of borderline AFI on pregnancy outcomes.
