placental basal plate

PBP

A maternal facing structure of the placental disc, adjacent to the intervillous space. Major components of the placental basal plate include decidua basalis, fibrinoid, connective tissue, extravillous trophoblasts, and residues of degenerating villi and maternal vessels.

Frequently Asked Questions

What is the placental basal plate?

The placental basal plate is the deepest layer of the placenta, composed of decidualized endometrium, anchoring chorionic villi, and containing placental septa.

Where is the placental basal plate located?

Located at the deepest margin of the placenta where it interfaces directly with the uterine wall and myometrium.

What is the function of the placental basal plate?

The basal plate anchors the chorionic villi to the uterus and contains the openings of spiral arteries that deliver maternal blood into the intervillous space.

What is the placental basal plate connected to?

The basal plate connects the chorionic villous tissue above to the maternal decidua and myometrium below through anchoring trophoblast and spiral arteries.

Why is the placental basal plate clinically important?

Abnormal placentation with invasion of trophoblast into the myometrium (placenta accreta spectrum) involves the basal plate and increases risk of massive postpartum hemorrhage.
