What causes fetal aortic arch hypoplasia?

Fetal aortic arch hypoplasia can be caused by developmental abnormalities, chromosomal abnormalities, parents’ bad habits during pregnancy, family genetics and other factors.
1. Developmental abnormality: abnormal development of the region forming the aortic arch during embryonic development can trigger aortic arch dysplasia, which can lead to malformation of the aortic arch and its branches.
2. Chromosomal anomalies: These mainly include deletion of genes related to the formation of the aortic arch, which can lead to dysplasia of the aortic arch and its branches.
3. Parents’ bad habits during pregnancy: Parents who smoke, drink or stay up late during pregnancy, or who have viral infections can cause aortic arch hypoplasia in the fetus.
4. Family genetics: Fetal aortic arch hypoplasia can be influenced by family genetics, and the incidence of aortic arch hypoplasia in children may increase when there is a parent with aortic arch hypoplasia.
Fetal aortic arch hypoplasia should be treated as soon as possible by a doctor and a specialist.
