Frequently Asked Questions

What is the placental septum?

A placental septum is a column of decidual connective tissue that extends from the basal plate into the intervillous space, partially subdividing placental territory.

Where is the placental septum located?

Placental septa originate from the basal plate and project upward into the intervillous space, forming partial partitions that create discrete placental lobules.

What is the function of the placental septum?

The septa provide structural organization to the placenta and define maternal blood supply territories, while not completely separating fetal villous blood circulations.

What is the placental septum connected to?

The septa originate from the basal plate and are surrounded by intervillous space containing maternal blood and fetal villi.

Why is the placental septum clinically important?

Septal abnormalities can lead to abnormal placental development patterns and are associated with conditions like placental abruption.
