Dilation of the ductus venosus by stent implantation increases placental blood perfusion in fetal sheep

The dilatation of the DV by means of stent implantation in the DV increased the blood flow volume rate in the umbilical vein. Fetal surviving mechanism, the increase of DV shunting rate including redistribution of the blood flow in the liver with a reduction of DV resistance to flow, could have a second effect: the improvement of reduced placental blood perfusion during hypoxia.
