title: Second trimester oligohydramnios, a predictor of poor fetal outcome.
abstract: Twelve cases of severe second trimester oligohydramnios are reported. The outcome of these pregnancies was uniformly poor, with no survivors in the present series. Four patients had therapeutic abortions, one woman had spontaneous labor at 22 weeks' gestation, and seven patients continued to viability. Of these, five patients had severe renal abnormalities incompatible with life. Two infants died at, or shortly after, birth from severe intrauterine growth retardation (IUGR), one of which had a triploid karyotype. Review of the literature shows a similar poor outcome for pregnancies with severe oligohydramnios in the second trimester.
