Neuropathological and anatomopathological analyses of acardiac and "normal" siblings in an acardiac-twin pregnancy.
Acardiac twinning is a very rare complication of multiple pregnancy. The authors present the neuropathological and anatomopathological description of the twins of the multiple pregnancy complicated by the acardiac foetus and terminated at 26 weeks of gestation. An anatomopathological examination of the "normal" twin showed hyaline membrane syndrome, cardiomegaly and hepatomegaly. Neuropathologically, numerous hypoxic-ischaemic lesions, most likely associated with haemodynamic disorders during pregnancy as well as less pronounced perinatal changes were revealed. The acardiac foetus, classified as acardius acephalus, demonstrated the presence of some abdominal organs and a histologically well-developed spinal cord. In view of the neuropathological changes, monitoring "normal" twins for discreet pathological central nervous system signs, which may be similar in character to those described, may play a significant role.
