Sudden intrauterine death associated with furcate insertion of the umbilical cord

In the case described, a completely uncomplicated pregnancy ended with a fatal outcome. Intrauterine fetal death, which was diagnosed prepartum at 40 weeks of gestation, was caused by hemorrhage of the fetus into the amniotic fluid following rupture of the umbilical vein at the site of furcate insertion of the umbilical cord. This insertion anomaly accompanied by rupture of a vessel occurs only very rarely but represents a placental cause of an abrupt and unpredicted end of a pregnancy. Although this process involved trauma, from a medico-legal point of view, there was no sign of external impact and death could, therefore, be classified as natural.
