The S/A index of ductus venosus Doppler of normal fetuses from 22 to 37 gestational week

Abstract

Prenatal Doppler ultrasound of ductus venosus plays an important role in evaluation of fetal circulation and fetal heart function.

Objectives: To create establish percentile chart of Ductus venosus S/a index among normal fetuses from 22 to 37 week.

Subject and method: there were 640 pregnant women from 22 to 37 week of gestation, all of them had Doppler ultrasound of Ductus venosus indices.

Methodology: this is a cross-sectional study.

Results: a high correlation between S/a index Ductus venosus and gestational week

Conclusions: This study have created percentile chart for: S/a index of Ductus venosus Doppler among normal fetuses from 22 to 37 week of gestation. This chart will be useful for appling to practice in clinical.
