A piece in the puzzle of intrauterine fetal death: pathological findings in placentas from term and preterm intrauterine fetal death pregnancies Academic Article uri icon


  • Objective. To compare pathological findings of placentas from term and preterm pregnancies complicated by intrauterine fetal death (IUFD).Study design. A retrospective cohort study was conducted including deliveries complicated by IUFD. A comparison was made between placentas from term and preterm (<37 weeks' gestation) pregnancies complicated by IUFD. A second analysis was undertaken comparing IUFD placentas delivered before and after 34 weeks' gestation. Uteroplacental insufficiency was defined when one or more of the following pathological features were found: placental infarct, poor vascularity of the chorionic villi, intravascular thrombi and vascular occlusion.Results. During the study period, 849 placentas of IUFD were examined. Gross and microscopic pathological finding were noted. When comparing gross and microscopic findings in term and preterm (<37 weeks) IUFD placentas, higher rates of calcifications, tissue congestion and cellular metaplasia were found in term vs. preterm placentas.
