Umbilical cord vasculitis is a relatively common occurance in placental pathology. It is thought to preceed funisitis and is closely related to chorioamnionitis.


  • Usually seen together with chorioamnionitis.
    • May be described as the fetal response to chorioamnionitis.[1]
  • Presence considered to be a good prognosticator.[1]



  • Neutrophils in the vessels of the umbilical cord.
  • Wharton's jelly without neutrophils.


  • Margination of neutrophils in the affected vessels is usually seen, and (in theory) precedes the development of vasculitis.
  • Umbilical vein involvement (umbilical phlebitis) precedes umbilical artery involvement (umbilical arteritis).[2]


  • Funisitis - neutrophils are also in the connective tissue of the umbilical cord (Wharton's jelly).


Umbilical cord vasculitis:[3]

  • +0.5 for each vessel.
  • +0.5 for each vessel with severe involvement.
