Abstract

The ductus venosus regulates the distribution of oxygen and placental nutrients by restricting the centralization of blood flow in fetal circulation. The ductus venosus is a small vein transmitting oxygen-rich blood from the umbilical vein to the fetal heart.. Increasing numbers of case reports are being published about ductus venosus agenesis with cardiac structural abnormalities, other malformations, chromosomal abnormalities, and stillbirth. Heart failure, hydrops and unexplained polyhydramnios could also be associated with ductus venosus agenesis. In the follow-up of fetuses with ductus venosus agenesis, care must be taken to examine for hydrops and heart failure. The agenesis of ductus venosus is often only found in fetuses by coincidentally. Herein we discuss the prenatal diagnosis of isolated agenesis of the ductus venosus presenting with a dilated inferior vena cava and without any disturbance of fetal hemodynamics and any other malformation. In conclusion a dilated inferior vena cava can be a sign of ductus venosus agenesia.

Highlights

Most maternal cardiac disease in Western There are profound differences in the cardiovascular system before and after birth
We report on the prenatal diagnosis of isolated agenesis of the ductus venosus presenting with a dilated inferior vena cava and without any disturbance of fetal hemodynamics and any other malformation
The vena cava inferior was seen to be dilated and the ductus venosus could not be viewed during venous blood flow studies at the routine obstetric ultrasound scan at 20 weeks’ gestation

Summary

Introduction

Most maternal cardiac disease in Western There are profound differences in the cardiovascular system before and after birth. The oxygenated blood from the placenta returns to the fetus through the umbilical venous system. About 20% to 30% (this percentage decreases in a growth-restricted fetus) of umbilical venous blood bypasses the liver through a narrow trumpet-shaped vessel called the ductus venosus. The ductus venosus regulates the distribution of oxygen and placental nutrients by restricting the centralization of blood flow.
