In almost every pregnancy feto-maternal transfusions occur. From the 6th week of pregnancy, blood containing Rhesus antigens may be infused into the maternal circulation and cause sensitization. In case of miscarriage, abortion, ectopic pregnancy and cystic mole the chance of fetomaternal transfusion followed by sensitization of the mother is significantly increased. Therefore immunoprophylaxis with anti-D-immunoglobins should be performed in all these cases.
