Blue arrows point to necrotic villi.
Separation of the placenta by retroplacental hemorrhage from the uterus prior to delivery of the fetus. May be compression and infarct of adjacent villi. Villous infarcts may be seen. Hemorrhage may be substantial and result in fetal mortality. Medline will open in a new window.
