Fetal anemia

Body
was changed:
Fetal anaemia can result from many causes.
Pathology
Aetiology
- haemolytic disease of the newborn
- fetal infections
- haematopoetic abnomalities
- homozygousalpha thalassaemia 7
- syndromes
- tumours
Radiographic features
Ultrasound
General sonographic features include:
- evidence of fetal hepatomegaly and/or fetal splenomegaly
- effects of subsequent cardiovascular compromise
- development ofhydrops fetalis
Doppler
- increase infetal middle cerebral arterial (MCA) Dopplertime average mean velocity (TAMV): may occur before precipitation of fetal hydrops
- increase in fetal middle cerebral arterial (MCA) Doppler peak systolic velocity (PSV): may occur before precipitation of fetal hydrops
- changes in fetal MCA Doppler are reported to have 88% sensitivity and a 82% specificity for detection of fetal anaemias
Fetal MRI

Treatment and prognosis
Intra-uterine transfusion via the umbilical vein can be successfully in selected cases. Overall prognosis will depend on underlying conditions and associations.
