Unexpected stillbirth from umbilical cord hematoma.

Background: 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.

Case Report: 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.

Conclusion: 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.
