Termination of pregnancy was not always based on a correct antenatal diagnosis. All fetuses but one from terminated pregnancies had evident anomalies. In six cases (1.8%) the decision to terminate was based on suboptimal prognostic and diagnostic information. Fetal autopsy by an experienced perinatal pathologist is essential to provide a definitive diagnosis.
We find an overall high degree of agreement between US and autopsy findings. Autopsy often provided additional information of clinical value and it should always follow US examination and TOP. Fixation of CNS is crucial for optimal results. Specific limitations of autopsy, i.e., detection of CNS abnormalities, may be reduced by complementary imaging techniques, such as MRI. The ability of US to detect cardiac anomalies is enhanced with the close contact to specialized fetal cardiology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
