What is a significant risk associated with velamentous cord insertion?

Velamentous cord insertion is an abnormality where the umbilical cord inserts into the fetal membranes rather than directly into the placental mass. This insertion can place the vessels at significant risk of rupture, especially if they are exposed and not protected by the placental tissue. If these vessels rupture during labor, it can lead to a rapid and severe hemorrhage. This risk of hemorrhage is considered one of the most critical complications associated with velamentous cord insertion and can endanger both the mother and the fetus.

In addition to this, while other complications related to the placenta, maternal hypertension, or fetal heart rate may arise in various contexts, they do not directly correlate with the specific risks posed by velamentous cord insertion. Hence, the risk of hemorrhage during labor is a significant concern needing careful monitoring in cases of velamentous cord insertion.
