Unexpected stillbirth from umbilical cord hematoma

Umbilical cord hematomas (UCHs) can cause life-threatening outcomes, although extremely uncommon. They can lead to fetal distress and stillbirth. They have been observed in about 1:5500 pregnancies; they are associated with poor outcome in about the 50% of all cases. UCHs commonly occur due to rupture/lesion of umbilical vein's walls, or less frequently of umbilical arteries' ones.

We present a case of a fetal demise which acutely and unexpectedly occurred in the last phases of labor. In this fetus, the identification of the cause of death was made only after post-mortem examination. The present report depicts the uncommon eventuality of umbilical cord hematomas which can cause unexpected fetal demise.

This case points out that in these cases careful examination of umbilical cord's macroscopic/microscopic examination is fundamental to clarify the natural cause of fetal death for statistical purposes; to close parents' mourning process; to ascertain medical malpractice claims.
