The umbilical vein is the only passage through which blood containing oxygen and nutrients is transported from the placenta to the fetus and leads the umbilical venous blood to the inferior vena cava in two ways, one by the liver and the other by the venous catheter. However, regarding the diversion of these two channels, different sources have different opinions [1 ~ 4].
