Corpus Callosum Length and Cerebellar Vermian Height in Fetal Growth Restriction

Abstract

Plain Language SummaryIn this study, we compared ultrasound measurements of several brain structures in fetuses with reduced or normal growth. We also evaluated the correlation of the size/length of these brain structures to blood flow of several blood vessels to the brain. We found that measurements of the small brain (CVH) are larger in pregnancies with growth problems. We also found that the blood flow of the vessel in the back side of the brain (vertebral artery [VA] Doppler) is inversely correlated with the CVH. These findings add to the literature on the use of ultrasound specifically to assess brain structures in pregnancies that are affected by growth problems. Deeper understanding of these associations may help establish which pregnancies with growth problems may need the most help later in life.
