Summary
Brief summary
The loss of a pregnancy, whether spontaneous or induced for medical reasons, is a very traumatic event for the parents. In many cases, the reasons for a fetal abnormality or miscarriage are not clear, but can be very important for future pregnancies and patient counselling. Fetal autopsy is performed (with parental consent) as often as possible, but some parents cannot consider autopsy at a very stressful time in their lives, and others cannot consent for cultural or religious reasons. Some of these parents will allow an external examination and x-rays which provide only limited information.
The use of multi-detector computed tomography (MDCT) is well established in forensic science units around the world. To date, there has been very little research into the value of MDCT in fetal deaths. A recent article by O’Donoghue et al. used MDCT as an adjunct to autopsy in the investigation of 3rd trimester stillbirths, finding good correlation between measurements obtained in both settings, although only half their cases underwent formal autopsy.1
We aim to investigate the value of MDCT as part of the investigation into fetal abnormalities and pregnancy losses in the 2nd and 3rd trimesters, and early neonatal period. While we do not propose to replace conventional autopsy, we hope to show a good correlation between radiological and pathological findings, so that we can offer a non-invasive alternative to autopsy where the parents cannot consent to dissection.
