Fundal Placenta

Definition - What does Fundal Placenta mean?

A fundal placenta is a placenta that is attached to the top wall—called the fundus —or upper zones of the uterus. The placenta is the organ that develops during pregnancy and serves to provide oxygen and nutrients to the developing baby through the umbilical cord. The placenta also removes waste products from the baby’s blood. The placenta can attach anywhere on the surface of the uterus, but a low-lying placenta can be problematic.

FertilitySmarts explains Fundal Placenta

The are five walls of the uterus: anterior, posterior, right lateral, left lateral, and fundal. The position of the placenta is determined on the basis placental attachment to any of these walls.

Various placental positions on the surface of the uterus are:

  • Anterior placenta, which is the front wall
  • Posterior placenta, which is the back wall
  • Lateral placenta, either left or right side
  • Fundal placenta, the top wall
  • Placenta previa, a low-lying placenta that remains low

Two combinations are possible with fundal placenta; it could be fundal anterior or fundal posterior.

Anterior fundal placenta means that the placenta is positioned on the front wall and the upper zone of the uterus, whereas posterior fundal placenta is positioned on the upper region of the back wall of the uterus. Both of these positions are normal.
