Usually this is not a problem many women with this condition deliver healthy babies.

Marginal insertion of umbilical cord. Insertion of the umbilical cord within 2 cm from the placental margin is described as marginal cord insertion usually defined as 2 cm 5 although some references define it as 1 cm 3 6. A marginal cord insertion simply means the umbilical cord is attached off center on the placenta and that the baby might not be getting the full benefit of nutrients the placenta has to offer. In the case of vcis and my 4th birth experience the umbilical cord inserts into the membranes of the amniotic sac where unprotected blood vessels run.

I was just diagnosed yesterday at my 20 week scan with what s called a marginal cord insertion or a battledore placenta. Velamentous insertion of the umbilical cord has been associated with an increased risk of adverse perinatal outcomes.

Marginal umbilical cord insertion only 7 of pregnancies have what is known as battledore cord insertion or marginal cord insertion. The umbilical cord connects within 2 cm of the placenta s edge instead of near the center.

In marginal insertion of umbilical cord the umbilical cord inserts into the edge of the placental disc of the developing fetus the umbilical cord lies within 2 cm of the placental disc edge there are no causative factors associated with marginal insertion of umbilical cord. However sometimes the cord inserts within 2 cm of the placenta edge called a marginal cord insertion mci or not into the placenta at all which is called a velamentous cord insertion vci 3.
