Official Title: Alterations of the Uteroplacental and Fetal Pulmonary Circulation in Patients With Severe Idiopathic Oligohydramnios Following Amnioinfusion Therapy in a Longitudinal Stud
Brief Summary: The aim of this study is to compare the uteroplacental and pulmonary circulation of the fetuses with severe (AFI<5cm) idiopathic oligohydramnios (with unknown origin) to those in normal controls. Further purpose of the study is to measure the changes of the uteroplacental and fetal pulmonary circulation in patients presenting with severe idiopathic oligohydramnios, managed either with single amnioinfusion or with serial amnioinfusions.
