What is circumvallate placenta?
Circumvallate placenta is an abnormality of the placenta. It causes the membranes of the placenta to fold back around its edges. It can increase the chance of complications such as preterm delivery and placental abruption, as well as increasing the risk of neonatal death and an emergency cesarean.
What is the placenta?
The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. ... The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.

What are the 4 types of placenta previa?
There are three different types of placenta previa: complete previa, partial previa and marginal previa. Complete placenta previa occurs when the placenta is completely covering the cervix.

Sometimes, a doctor may discover a circumvallate placenta using an ultrasound. In other cases, they may not diagnose the condition until delivery.
What happens when the placenta abruptly detaches?
Placental abruption: In this emergency, the placenta suddenly detaches, putting the fetus at risk. Placental abruption affected 10.9% of the women.

Why Fold?
