ABO fetomaternal compatibility poses a risk for massive fetomaternal transplacental hemorrhage

Abstract

Severe fetomaternal transplacental hemorrhage increases the risk of fetal anemia. In the third trimester, the syncytiotrophoblast becomes thinner, especially in areas where it comes into intimate contact with villous capillaries, and forms a vasculosyncytial membrane.

Our aim was to determine whether ABO compatibility puts the fetus at a greater risk of severe fetomaternal hemorrhage.
