The aim of our study was to evaluate the middle cerebral artery velocimetry before and after
intrauterine blood transfusion in
immune hydrops fetalis. The current study was conducted in a tertiary research hospital, from February 2009 to January 2011. Nineteen
intrauterine blood transfusions performed during the study period. The factors recorded were age of the mothers, gestational weeks, pre-
transfusion fetal hematocrit and post-
transfusion fetal hematocrit, and also middle cerebral artery peak systolic velocimetry (MCA-PSV) was detected and recorded before and after
intrauterine transfusion. A control group of twenty two cases for normal MCA doppler velocimetry was also included to the study. During the study, a total of eleven rhesus isoimmunized pregnancies underwent
intrauterine blood transfusions at our perinatal diagnose unit. Before transfusion seventeen severe and two moderate
anemias were detected and mean MoM of MCA-PSV was 1.76±0.38 MoM. Post transfusion mean MoM of MCA-PSV in the patient group and control group were 1.08±0.22 MoM and 0.96±0.21 MoM, respectively. The mean MCA-PSV values were higher in RI fetuses than post transfusion and control group. In current study, we found that MCA-PSV is a valuable parameter in detecting fetal
anemia requiring
intrauterine transfusion and mean MCA-PSV values is higher than 1.5 MoM in fetuses with
anemia. And also decrease in MCA-PSV just after transfusion in anemic fetuses showed the quick response of the fetus to correction of
anemia.
