Maternal Floor Infarction. This extreme variant of perivillous fibrin
deposition is a dense fibrinoid layer within the placental basal plate and is
erroneously termed an infarction. Maternal floor infarction has a thick,
yellow or white, firm corrugated surface that impedes normal maternal blood
flow into the intervillous space. In specific cases that extend up and beyond
the basal plate to entrap villi and obliterate the intervillous space, the term
massive perivillous fibrin deposition is used. The etiopathogenesis is
unclear, but maternal auto- or alloimmunity appears contributory (FayePeterson, 2018; Romero, 2013). Antiphospholipid antibody syndrome and
angiogenic factors involved with preeclampsia also have been implicated

Study Notes
Previous Cesarean Birth
- Two main options for patients who have undergone a previous cesarean birth in a subsequent pregnancy:
- TOLAC stands for Trial of Labor After Cesarean
- Decision-making regarding mode of birth should take into consideration individual circumstances and risks
Maternal Floor Infarction
- Maternal floor infarction is a dense fibrinoid layer within the placental basal plate
- It impedes normal maternal blood flow into the intervillous space
- Characterized by a thick, yellow or white, firm corrugated surface
- In severe cases, it can extend up and beyond the basal plate, entrapping villi and obliterating the intervillous space, and is termed massive perivillous fibrin deposition
- Etiopathogenesis is unclear, but maternal auto- or alloimmunity appears contributory
- Antiphospholipid antibody syndrome and angiogenic factors involved with preeclampsia have been implicated in the development of maternal floor infarction
