Two vessel umbilical cord
From Libre Pathology
(Redirected from Two vessel cord)
Two vessel umbilical cord, also two vessel cord and single umbilical artery, is an abnormality seen in placental pathology.
- Associated with congenital abnormalities, esp. cardiac - key point.
- 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.
- Associated with maternal diabetes.
- Two vessels in the umbilical cord.
- Two vessels in the umbilical cord - one artery and one vein.
