Overview

Abstract:

Prenatal doppler ultrasound of the ductus
venosus plays an important role in the
evaluation of fetal circulation and fetal heart
function. We aimed to establish the
percentile of Resistivity Index (RI) and
Pulsatility Index (PI) of the Ductus Venosus
(DV) among normal Vietnamese fetuses
with a gestation from 22 to 37 weeks in a
cohort study. Normal Vietnamese fetuses
with a gestation ranging from 22 to 37 weeks
were examined in a cohort study. The PI and
RI were recorded from the DV. We analyzed
640 participants who all fulfilled the
inclusion and exclusion criteria of our study.
Results: There was a significant correlation
between RI, PI and gestational age as shown
with the equations y = 0.077x – 0.003x
2 +
3.493e - 5x
3 (r=0.97) and y = 0.106x –
0
.004x2 + 4.5e - 5x3 (r=0.94), respectively.
A centile module was constructed for the DV
RI and PI indices among normal Vietnamese
fetuses with gestation from 22 to 37 weeks.
