Doppler ultrasound in obstetrics

Doppler ultrasound is used to assess and monitor high-risk pregnancies and time delivery appropriately. Pregnancies with high resistance in the uterine arteries (UtA) are at risk of pre-eclampsia and fetal growth restriction (FGR) and need close monitoring. Umbilical artery Doppler reflects blood flow within the placenta and increased resistance within the umbilical arteries (UmA) reflects placental dysfunction. In situations with abnormal UmA blood flows, further assessment of fetal Dopplers such as middle cerebral artery (MCA) and ductus venosus (DV) enables timely delivery by identifying progressive changes in fetal circulation with progressive hypoxia.
