[Doppler blood flow velocity in the evaluation of fetal anemia].

OBJECTIVE

To review (summarize), in maternal red blood cell alloimmunization, the diagnostic value of Doppler blood flow velocity in the evaluation and prediction of fetal anemia.

DESIGN

A review article.

SETTING

Department of Obstetric and Gynecology, University Hospital, Olomouc.

SUBJECT AND METHOD: A review from literature and bibliographic databases.

CONCLUSION

Invasive techniques such as amniocentesis and cordocentesis traditionally are used for diagnosis and treatment in fetuses at risk for anemia due to maternal red-cell alloimmunization. Middle cerebral artery peak systolic velocity is a highly sensitive non-invasive means for determining the degree of anemia. The interval of seven days between two Doppler tests is recommended. The widespread use of the Doppler method will minimize fetal complications associated with amniocentesis and fetal blood sampling and may significantly lower health care cost.
