[Acute fetal posthemorrhagic anemia in incomplete rupture of the umbilical cord].

The present paper communicates a case of acute fetal posthemorrhagic anemia. In the case in question, this rare event occurred during birth and had no consequences for the infant thanks to rapid neonatologic intervention. The cause was found to be an incomplete funicular hernia associated with velamentous insertion. The importance of funicular hernias as the most serious umbilical cord complication is discussed with reference to this case and the literature.
