Background: Goal of this study is to consider the incidence of chromosomal abnormalities in fetuses by velocimetry abnormalities.
Methods: The author select 64 pregnancies by velocimetry abnormalities of umbilical artery diastolic flow (ARED: Absent or Reverse end Diastolic Flow).
Results: The fetal cariotype from amniociti or from umbilical blood at delivery moment is resulted abnormal in 5 cases. Fetal-maternal risk factors of chromosomopaties are: malformations; fetal growth retardation; maternal age > or = 35.
Conclusions: Other studies and other results are necessary for this discussion.
