maternal floor infarction

maternal floor infarction

A pathologic entity characterised by deposition of fibrinoid material in the maternal surface and intervillous spaces of the placenta, and which is associated with significant perinatal morbidity and mortality including stillbirth, recurrent pregnancy loss, premature delivery, intrauterine growth restriction and neurodevelopmental impairment.

Some lesions, such as chronic intervillositis, high-grade villitis of unknown etiology, and maternal floor infarction, are important by virtue of their high recurrence risk and their association with adverse pregnancy outcomes.

Chronic histiocytic intervillositis has been suggested to be along the spectrum of the more recognized lesion known as villitis of unknown etiology, (5) along with massive perivillous fibrin deposition and maternal floor infarction. (6) Increased perivillous fibrin is often seen in association with CHI.
