Velamentous Cord Insertion of the Placenta

Clinical term for describing a placental abnormality where the placental cord inserts into the chorion laeve (placental membranes) away from the edge of the placenta.

The placental vessels are therefore unprotected by Wharton's jelly where they traverse the membranes before they come together into the umbilical cord.

This can cause hemorrhage if the vessels are damaged when the membranes are ruptured prior to birth.

The condition is more common in monozygotic twins (15%) and triplets.
