[Role of middle cerebral artery Doppler in the management of Rhesus alloimmunization cases].

Background: The most common cause of anemia remains fetal red cell alloimmunization. Although after the systematization of prophylactic anti-D gamma globulin decreased the number of cases, has not eliminated the problem.

Objectives: To evaluate the role of the fetal middle cerebral artery peak systolic velocity in the management of fetus at risk for anemia due to Rh alloimmunization and analyze the effect in perinatal outcomes.
