|Micrograph of a placental infarct. H&E stain.|
Small placental infarcts, especially at the edge of the placental disc, are considered to be normal at term. Large placental infarcts are associated with vascular abnormalities, e.g. hypertrophic decidual vasculopathy, as seen in hypertension. Very large infarcts lead to placental insufficiency and may result in fetal death.
