Hydrops Fetalis
Pronunciation: HY-drops fe-TAL-is
Abnormal accumulation of fluid in fetal body cavities and tissues, often requiring urgent postnatal surgical intervention.
Full Definition
Hydrops fetalis is a serious fetal condition characterized by abnormal accumulation of fluid in two or more fetal body compartments, including pleural effusion, pericardial effusion, ascites, and subcutaneous edema. The condition is classified as immune (due to maternal antibodies against fetal red blood cells) or non-immune hydrops. Non-immune causes include cardiac anomalies, chromosomal abnormalities, infections, and thoracic masses. In pediatric surgery, hydrops may complicate conditions such as congenital cystic adenomatoid malformation or bronchopulmonary sequestration. Affected neonates often require immediate resuscitation and may need emergent drainage procedures. The overall prognosis depends on the underlying etiology and severity of the condition.
