Maternal outcomes of a cohort of pregnancies affected by non-immune hydrops fetalis.

Our study identified several important adverse outcomes of pregnancies complicated by NIHF with negative standard-of-care evaluations, including a high rate of postpartum pre-eclampsia and worsened mental health. We identified a higher rate of cesarean delivery and preterm birth, both primarily for fetal indications. We also observed the known relationship between polyhydramnios, hemorrhage, and atony, but noted that this risk included pregnancies concluding in dilation and evacuation. Counseling after a diagnosis of NIHF should include these adverse outcomes.
