fetal hydrops
Pronunciation: HIGH-drops
Abnormal accumulation of fluid in fetal tissues and body cavities, indicating severe fetal compromise.
Full Definition
Fetal hydrops is a serious condition characterized by excessive fluid accumulation in fetal tissues and body cavities, including ascites, pleural effusion, pericardial effusion, and skin edema. It is classified as immune hydrops (caused by maternal alloimmunization, particularly Rh disease) or non-immune hydrops (with multiple potential causes including cardiac abnormalities, infections, chromosomal disorders, and twin-to-twin transfusion syndrome). Non-immune hydrops is more common in developed countries due to Rh immunoprophylaxis. The condition carries a poor prognosis, with high rates of intrauterine fetal death and neonatal morbidity. Early diagnosis through ultrasound allows for targeted investigation and potential in-utero treatment.
