Survival of fetuses with severe oligohydramnios

Abstract

Objective: The aim of the present study was to identify predictive data on the short-term outcomes of fetuses with oligohydramnios. Materials and Methods: A retrospective study of all pregnancies diagnosed with oligohydramnios was performed. Results: A total of 17 fetuses (seven males, seven females, and three unknown) with oligohydramnios were treated from 2004 to 2011. Oligohydramnios was first diagnosed at a 21.6 ± 4.2 weeks gestation. Terminations of pregnancy before 22 weeks were identified in five cases, and intrauterine fetal deaths occurred in two cases. Ten neonates were born alive, five cases survived over 28 days, and five cases died within 48 hours. Prognostic factors for survival included birth weight (2,457 ± 480 grams in survivors vs. 1973 ± 124 grams in non-survivors; p < 0.05) and the mean amniotic fluid index (AFI) (2.32 ± 1.19 cm in survivors vs. 0.46 ± 0.68 cm in non-survivors; p < 0.05). Conclusion: All patients who survived had a mean AFI > 1.0 cm.
