title: Polyhydramnios with bidirectional fetal ductus arteriosus flow in a fetus with congenital diaphragmatic hernia: case report.
abstract: The etiology of polyhydramnios may be attributed to either increased production of amniotic fluid (fetal polyuria or high-output cardiac failure) or decreased fetal swallowing (obstruction or neurological impairment). Although idiopathic polyhydramnios occurs in nearly half of all cases, it is often associated with fetal abnormalities. Fetal ductus arteriosus flow is normally from right to left. We report a case of antenatally detected bidirectional fetal ductus arteriosus flow diagnosed concomitantly with polyhydramnios. Amnioreduction was performed due to severe maternal symptoms, which resulted in correction of the fetal ductus arteriosus flow. Postnatal diagnosis of a Morgagni diaphragmatic hernia indicates that our sonographic findings collectively may have been a diagnostic clue.
