Radiographic evaluation of stillbirth: what does it contribute?
2014
Despite advances in perinatal care, stillbirth is relatively common (1/160 births) and frequently remains unexplained. Most recent protocols for etiologic evaluation of stillbirth either omit radiography or reserve it for infants with obvious skeletal disproportion. Over the past 30 years, the Wisconsin Stillbirth Service Program has collected radiographic images from 2,032 stillbirths and second trimester losses, of which about 25% (517) showed abnormalities. Review of these images by a medical geneticist showed that radiographs yielded a diagnosis in 45% of the infants with abnormalities (11.5% of all radiographs obtained) and were critical, yielding a diagnosis that would otherwise have been missed or incomplete in 1.5% of the total infants. The probability of a diagnosis was not significantly different between miscarriages <20 weeks and stillbirths. Diagnoses were mainly fetal, most commonly sporadic birth defects, idiopathic hydrops, chromosome abnormalities, and skeletal dysplasias, but chorioamnionitis with fetal sepsis, complications of twinning, and cord accidents were also diagnosed radiographically. Radiographs may help direct the use of newer technologies such as chromosomal microarray or gene sequencing. Limiting radiographs to infants with obvious skeletal disproportion would have resulted in many of these diagnoses, including 4/24 skeletal dysplasias, being overlooked. We recommend at least an anterior/posterior babygram film as part of the permanent record of all second trimester losses and stillbirths. © 2014 Wiley Periodicals, Inc.
