Results of full postmortem examination in a cohort of clinically unexplained stillbirths: undetected fetal growth restriction and placental insufficiency are prevalent findings.

In total, 60.5% of CUS were diagnosed at postmortem to have fetal growth restriction and/or placental insufficiency. The mean gestational age of death in which these conditions presented was 32.7 weeks and 35.5 weeks, respectively, suggesting a critical time-frame to monitor to potentially reduce stillbirth occurrence.
