Limb deformations in Oligohydramnios sequence: effects of gestational age and duration of Oligohydramnios.
American journal of medical genetics, 1999Co-Authors: Caitlin Christianson, Dale Huff, Elizabeth McphersonAbstract:In order to study the pathogenesis of prenatal deformities, we reviewed maternal histories, delivery records, pathology reports, radiographs, and photographs of 90 fetuses with prenatally documented Oligohydramnios at gestational ages from 14 weeks to term. The causes of Oligohydramnios included premature rupture of membranes (44 cases), fetal renal insufficiency (25 cases), idiopathic (15 cases), and twin-twin transfusion (6 cases). The fetuses were grouped according to gestational age at delivery and duration of Oligohydramnios. Sixty-three fetuses (70%) had documented contractures. As expected, contractures were more frequent with earlier onset and longer duration of Oligohydramnios. During the 2nd trimester, the frequency of contractures in fetuses with Oligohydramnios was 77% compared to 52% in the 3rd trimester (chi(2) = 5.33, 1 df, P =.02). Considering all gestational ages together, 57% of fetuses had contractures after less than 2 weeks of Oligohydramnios compared to 81% of fetuses with a longer duration of Oligohydramnios (chi2 = 6.23, 1 df, P

outcome of singleton pregnancies with severe Oligohydramnios in the second and third trimesters
Ultrasound in Obstetrics & Gynecology, 1996Co-Authors: Thomas D Shipp, Bryann Bromley, Stephen G Pauker, F D Frigoletto, Beryl R BenacerrafAbstract:We evaluated the significance of severe Oligohydramnios, or anhydramnios, in the second and third trimesters, by determining the range of etiologies as well as the differences in fetal and neonatal outcome. All prenatal ultrasound results on pregnancies found to have severe Oligohydramnios over a 7.5-year period at 13-42 weeks' gestation were retrospectively collected. Follow-up results were obtained from review of medical records, autopsies and pathology reports. A total of 250 singleton pregnancies met the criteria of having severe Oligohydramnios. A bimodal distribution in gestational age at diagnosis was seen, with more cases diagnosed at 13-21 weeks and at 34-42 weeks. Fetal abnormalities were present in 50.7% of those diagnosed with severe Oligohydramnios in the second trimester and in 22.1% of those in the third trimester. There were 10.2% and 85.3% survivors when severe Oligohydramnios was diagnosed in the second and third trimesters, respectively. The rate of aneuploidy was at least 4.4% for the entire singleton population. A bimodal distribution of pregnancies presenting with severe Oligohydramnios represents two different naturally occurring populations in terms of both etiology and prognosis.
