Background: The ductus venosus

What is ductus venosus flow?

The ductus venosus (DV) is a tiny vein connecting the umbilical circulation directly to the inferior vena cava where 20–30% of the highly oxygenated blood from the placenta bypasses the hepatic circulation and flows through the ductus venosus directly towards the foramen ovale into the left atrium [1].

What is the normal range of ductus venosus?

A statistical analysis of our cohort revealed that DV PIV values less than 0.73 and more than 1.22 were beyond the normal range. The mean S-wave, D-wave, a-wave, and TAMXV values were 31.18, 25.64, 8.68, and 22.72 cm/s, respectively. Conclusions: The value of DV PIV measurements is debated in the literature.
