Fetal anomaly
Structural or chromosomal abnormality detected during prenatal screening or diagnostic testing.
Full Definition
A fetal anomaly is any deviation from normal fetal development, including structural malformations, chromosomal abnormalities, or genetic disorders detectable through prenatal screening methods. These anomalies can range from minor variations that require no intervention to severe conditions incompatible with life. Detection methods include ultrasound imaging, maternal serum screening, and invasive diagnostic procedures. Fetal anomalies may be isolated findings or part of recognizable syndromes, and their identification influences pregnancy management, delivery planning, and postnatal care coordination.
Usage
Usage note: Preferred over 'fetal abnormality' in clinical documentation. Use specific terminology when the type of anomaly is known.
