A 27-year-old G2P1 at 29 weeks’ gestation who is being followed for Rh isoimmunization presents for her OB visit. The fundal height is noted to be 33 cm. An ultrasound reveals fetal ascites and a pericardial effusion.
Which of the following can be another finding in fetal hydrops?
A. OligohydramniosCharacteristics of fetal hydrops include abnormal fluid in two or more sites such as the thorax, abdomen, and skin. Fetal hydrops occurs as a result of excessive and prolonged hemolysis which causes anemia. This stimulates erythroid hyperplasia of the bone marrow and extramedullary hematopoiesis in the liver and spleen. The placenta is also markedly erythematous, enlarged, and boggy. Hydrothorax may be so severe that it may restrict lung development and cause pulmonary compromise after delivery. Ascites, hepatomegaly, and splenomegaly may lead to severe dystocia. Hydropic changes are easily seen on fetal ultrasound.
