fetal anemia
Abnormally low fetal hemoglobin levels, typically diagnosed through middle cerebral artery Doppler measurements or cordocentesis.
Full Definition
Fetal anemia is a condition characterized by abnormally low fetal hemoglobin levels, which can result from various causes including alloimmunization, parvovirus B19 infection, or fetomaternal hemorrhage. Diagnosis is typically made non-invasively through middle cerebral artery peak systolic velocity measurements on Doppler ultrasound, which correlate with fetal hemoglobin levels. Severe fetal anemia can lead to hydrops fetalis and requires prompt intervention, often including intrauterine blood transfusion.
Usage
Usage note: Both 'anemia' and 'anaemia' spellings are acceptable; use consistently within documents.
In Context
- "Elevated middle cerebral artery peak systolic velocity suggested moderate fetal anemia." — Ultrasound interpretation
