Current Controversies in Prenatal Diagnosis 2: Conventional Postmortem Examination Remains the Gold Standard for the Anatomical Examination of Fetal Loss.

A comprehensive postmortem examination is an essential component of a work-up after stillbirth. Its findings can support accurate counseling of parents about causes and risk of recurrence. It also supports providers' decisions about most appropriate testing and management plans for future pregnancy to prevent recurrence. Informing parents about fetal autopsy and obtaining their consent is challenging, and conducting a fetal autopsy requires expertise that is, not universally available. Newer non-invasive or minimally invasive methods such as postmortem MRI and targeted biopsies can replace or supplement autopsies, but one must recognize that expertise in these methods is likewise not broadly available. This prompts the question whether a conventional postmortem examination should remain the gold standard for the anatomical examination of fetal loss. This report summarizes the "for" and "against" arguments made by two experts during a debate at the 28th International Conference on Prenatal Diagnosis and Therapy. Arguments favoring comprehensive fetal autopsy include the need to obtain the most complete and accurate information about the cause of the stillbirth. Arguments in favor of less invasive post-mortem examinations using other technologies include sufficiency in many instances and a more equitable and cost-effective approach to postmortem examination. While both debaters weighed the balance of these conflicting arguments differently, they agreed that more research in this area is needed.
