hydrops fetalis
Pronunciation: HIGH-drops fee-TAH-lis
Abnormal fluid accumulation in fetal tissues and body cavities, often indicating severe fetal compromise.
Full Definition
Hydrops fetalis is a serious condition characterized by abnormal fluid accumulation in two or more fetal body compartments, including ascites, pleural effusion, pericardial effusion, or generalized skin edema. The condition may be immune-mediated (due to maternal alloimmunization) or non-immune (various etiologies including cardiac defects, infections, or genetic conditions). In fetal surgery contexts, hydrops may develop as a complication of the underlying condition or the procedure itself, often indicating poor prognosis and requiring immediate intervention.
Usage
Usage note: Specify immune vs. non-immune type when etiology is known; always describe fluid locations.
