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.
