Quick Summary

Velamentous insertion of the umbilical cord is a dangerous condition where the cord's blood vessels spread out over the membranes and cervix instead of forming a single, unified cord. This anomaly poses a significant risk to the baby because these exposed vessels can be torn or compressed during labor and delivery. The umbilical cord itself is a vital structure, connecting the fetus to the placenta and facilitating the exchange of nutrients, oxygen, and waste products between mother and baby. It contains arteries and a vein that transport blood to and from the placenta. While "false knots" in the cord are harmless, actual knots or twisting can be fatal to the fetus by cutting off blood supply. Extreme shortness of the cord can also lead to complications during delivery or fetal hemorrhage.12
