Definition / general
  • Intrauterine fetal demise that may be due to maternal factors (diabetes, preeclampsia, infection), placental abnormalities (vasculopathy, ischemia, infarction) or fetal anomalies (chromosomal disorders, congenital anomalies, Arch Pathol Lab Med 1976;100:367)
  • Chorioamnionitis, deciduitis or villitis may be present, thus warranting culture of the placenta
Gross description
  • Degree of maceration of the fetus and involution of the placenta are helpful indicators for the length of intrauterine demise
Microscopic (histologic) description
  • Microscopic changes are similar to those seen in fetal thrombotic vasculopathy (FTV) but are seen diffusely throughout the placenta
  • Early / recent demise ( > 24 - 48 hours) shows nuclear debris in blood vessels or villous vessels
  • This is followed by vascular septation in larger vessels with sequential changes in smaller vessels and terminal villi then villous fibrosis
  • Other nonspecific changes include calcification / increased mineralization of the trophoblastic basement membrane
