[Fetomaternal alloimmunization: role of cordocentesis]

Area of Science:

• Maternal-Fetal Medicine
• Immunology
• Genetics

Context:

• Alloimmunization poses significant risks during pregnancy.
• Management strategies are crucial for preventing fetal complications.
• Outpatient management offers a viable approach for selected cases.

Purpose:

• To evaluate the efficacy of outpatient intravascular management for alloimmunized pregnancies.
• To assess the role of fetal blood typing and hematocrit determination in guiding treatment.
• To analyze outcomes in pregnancies with and without prior fetal compromise.

Summary:

• Twenty-one pregnancies complicated by alloimmunization were managed outpatient using intravascular methods.
• Fetal blood type and hematocrit guided individualized treatment, including 19 intrauterine transfusions and 59 cordocenteses.
• Two patient groups were studied: those with prior severely affected fetuses and those without, including at-risk cases.

Impact:

• Demonstrates the feasibility and effectiveness of outpatient management for alloimmunized pregnancies.
• Highlights the importance of fetal diagnostics in tailoring treatment protocols.
• Contributes to improved perinatal outcomes in pregnancies affected by red blood cell alloimmunization.
