  • 1. Accompanying slides for:How to record ductus venosus blood velocityW.P. Martins & T. KiserudUltrasound Obstet Gynecol, 2013DOI: 10.1002/uog.11082
  • 2. How to: record the fetal ductus venosus blood velocity inthe second half of pregnancyIndication: hemodynamic evaluation, e.g. intrauterinegrowth restriction and cardiac functionMachine settings: routine obstetric scan preset withcolor Doppler velocity 30–40 cm/s, pulsed wave Dopplervelocity 80–100 cm/s, low filter (50–100 Hz) and pulsedDoppler sample volume 2–5 mmIdeal fetal lie: on back
  • 3. 1. Identify the umbilical vein in either a sagittal ortransverse planeSagittal Transverse
  • 4. 2. Tilt the probe so that it is in line with the direction ofblood flow through the DV, regardless of fetal lieSagittal Transverse
  • 5. 3. Magnify the imageSagittal Transverse
  • 6. 4. Apply color DopplerSagittal Transverse
  • 7. 5. Place pulsed Doppler sample in the typical brighteror aliasing area, and acquire waveformSagittal Transverse
