Two vessel umbilical cord, also two vessel cord and single umbilical artery, is an abnormality seen in placental pathology.

General

Associations:

  • Associated with congenital abnormalities, esp. cardiac - key point.[1]
    • Thought to be an acquired defect (as prevalence is lower early in gestation).
  • May be seen in association of other cord abnormalities (e.g. marginal insertion, velamentous insertion).
  • In apparently well (liveborn) infants it is associated with (occult) renal abnormalities, specifically vesico-ureteric reflux; there is no evidence for other abnormalities.[2]
  • Associated with maternal diabetes.[3]

Gross

  • Two vessels in the umbilical cord.

Microscopic

Features:

  • Two vessels in the umbilical cord - one artery and one vein.
