OP06.18: Prenatal diagnosis of non‐immune hydrops fetalis

26.3 weeks of gestation. Other 4 women were referred to our University hospital because of maternal trauma. Mean gestational age was 28.6. In all the fetuses the MCA-PSV was >1.5 MoM according to the reference range of Mari et al, and showed sinusoidal pattern during cardiotocography. Mean time of delivery has been of 47 hours because of abruptio placenta. In the other 4 women the MCA-PSV was normal as well as the cardiotocography pattern and delivered in a mean time of 8 hours because of acute abruptio placenta. Conclusion: MCA-PSV has a great sensibility in the prediction of fetal anemia, in case of maternal-fetal hemorrhage the fetuses may be anemic in case of chronic bleeding from the placenta, while in case the bleeding is acute MCA-PSV is usually normal. Thus the assessment of the MCA-PSV may be helpful to look for sign of fetal anemia in case of maternal-fetal hemorrhage.
