Velamentous cord insertion Velamentous cord insertion Velamentous cord insertion is an abnormal condition during pregnancy. Normally, the umbilical cord inserts into the middle of the placenta as it develops. In velamentous cord insertion, the umbilical cord inserts into the fetal membranes (choriamniotic membranes), then travels within the membranes to the placenta (between the amnion and the chorion). The exposed vessels are not protected by Wharton's jelly and hence are vulnerable to rupture. Rupture is especially likely if the vessels are near the cervix, in which case they may rupture in early labor, likely resulting in a stillbirth. This is a serious condition called
Umbilical line left portal vein, passing through the patent ductus venosus to the inferior vena cava and right atrium. Appropriate UVC tip position is in the high inferior vena cava to the low right atrium, typically within 1 cm of the diaphragm. If the UVC tip is proximal to ductus venosus it can lead to administration of intravenous fluids into the portal system, with potential portal vein thrombosis, or, in cases of TPN administration, a TPN abscess. Umbilical line An umbilical line is a catheter that is inserted into one of the two arteries or the vein of the umbilical cord. Generally
