'''Umbilical cord vasculitis''' is a relatively common occurance in [[placenta|placental pathology]]. It is thought to preceed [[funisitis]] and is closely related to [[chorioamnionitis]]. | |||
==General== | |||
*Usually seen together with [[chorioamnionitis]]. | |||
**May be described as the ''fetal response'' to chorioamnionitis.<ref name=pmid14749651/> | |||
*Presence considered to be a good prognosticator.<ref name=pmid14749651>{{Cite journal | last1 = Lahra | first1 = MM. | last2 = Jeffery | first2 = HE. | title = A fetal response to chorioamnionitis is associated with early survival after preterm birth. | journal = Am J Obstet Gynecol | volume = 190 | issue = 1 | pages = 147-51 | month = Jan | year = 2004 | doi = 10.1016/j.ajog.2003.07.012 | PMID = 14749651 }} | |||

Features: | |||
*[[Neutrophil]]s in the vessels of the umbilical cord. | |||
*Wharton's jelly without neutrophils. | |||
Notes: | |||
*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).<ref name=pmid21090086>{{Cite journal | last1 = Vedovato | first1 = S. | last2 = Zanardo | first2 = V. | title = [Chorioamnionitis and inflammatory disease in the premature newborn infant]. | journal = Minerva Pediatr | volume = 62 | issue = 3 Suppl 1 | pages = 155-6 | month = Jun | year = 2010 | doi = | PMID = 21090086 }}</ref> | |||

*[[Funisitis]] - neutrophils are ''also'' in the connective tissue of the umbilical cord (Wharton's jelly). | |||
