Comparison of ductus venosus Doppler velocimetry in appropriate for gestational age and severely growth restricted fetuses
Comparison of ductus venosus Doppler velocimetry in appropriate for gestational age and severely growth restricted fetuses
Ductus venosus Doppler in an AGA fetus (A) and (B) severe FGR at 27 weeks of gestation. Note that the a-wave is reversed in this case of severe FGR.
S: peak systolic velocity; D: first part of the diastole (passive filling of the ventricles); a: second part of diastole (atrial contraction); AGA: appropriate for gestational age; FGR: fetal growth restriction.
