Abstract

Rh alloimmunization occurs when maternal immune system is sensitized to D(Rh) erythrocyte surface antigens.The most common causes of maternal Rh alloimmunisation are blood transfusion and antepartum or intrapartum fetomaternal hemorrhage (abdominal trauma, abortion, ectopic pregnancy, invasive obstetric procedures, placental abruption, external cephalic version).The risk of alloimmunization is affected by several factors, including the degree of fetomaternal hemorrhage and maternal immune respons.Although the introduction of anti D prophylaxis reduced dramatically the rate of alloimmunization in susceptible women, his prevention is not universal and about 0.3% of susceptible women still become Rh D alloimmunized.The aim of this article is to review the management of the Rh alloimmunizated pregnant.

Keywords: alloimmunisation; anti D prophilaxis; fetal anemia.
