[Intrauterine fetal death after strangulation of the umbilical cord by amniotic bands].

The amniotic band sequence includes a number of typical fetal developmental anomalies that appear as disruption, amputation or deformation, dependent on the time of origin of the amniotic bands. In rare cases, amniotic bands can cause intrauterine fetal death by constriction of the umbilical cord. Clinical and pathologic-anatomical findings of two cases of intrauterine fetal death in the 21st and 34th week of gestation after torsion and strangulation of the umbilical cord by amniotic bands are presented.
