Presentation Transcript

  1. Accompanying slides for: How to record ductus venosus blood velocity in the second half of pregnancy W.P. Martins & T. Kiserud Ultrasound Obstet Gynecol, 2013 DOI: 10.1002/uog.11082

  2. How to: record the fetal ductus venosus blood velocity in the second half of pregnancy Indication: hemodynamic evaluation, e.g. intrauterine growth restriction and cardiac function Machine settings: routine obstetric scan preset with color Doppler velocity 30–40 cm/s, pulsed wave Doppler velocity 80–100 cm/s, low filter (50–100 Hz) and pulsed Doppler sample volume 2–5 mm Ideal fetal lie: on back

  3. 1. Identify the umbilical vein in either a sagittal or transverse plane Sagittal Transverse

  4. 2. Tilt the probe so that it is in line with the direction of blood flow through the DV, regardless of fetal lie Sagittal Transverse

  5. 3. Magnify the image Sagittal Transverse

  6. 4. Apply color Doppler Sagittal Transverse

  7. 5. Place pulsed Doppler sample in the typical brighteror aliasing area, and acquire waveform Sagittal Transverse
