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.
