What reason is fetal scalp oedema?
It is mainly due to the incompatibility of Rh / ABO blood group between mother and infant, resulting in the same family immune reaction, resulting in fetal hemolytic anemia, and finally lead to fetal edema. It is more common to be caused by other homologous immune systems such as C and e antigens or other blood group systems such as Kell and FY antigens.
The etiology of non immune fetal edema is complex, including cardiovascular malformations, chromosomal abnormalities, intrauterine infection, twin transfusion syndrome and severe anemia, resulting in fetal heart failure or intrauterine distress, continuous activation of renin-angiotensin system and fetal edema. In addition, 44% of fetuses had edema of unknown origin.
Uterine infection with bacterial viruses, such as parvovirus, Streptococcus, spirochete, cytomegalovirus, coxsackievirus, Toxoplasma gondii, etc. Capillary leakage caused by ischemia caused by severe anemia, portal and umbilical hypertension caused by dysfunction of liver parenchyma caused by extramedullary hematopoiesis, and decrease of colloidal osmotic pressure caused by hypoproteinemia caused by liver dysfunction.
