Associations (#11178630#)

- maternal conditions

  • systemic diseases
  • delivery complications
  • increased maternal age

- fetal conditions

  • non-reassuring fetal status
  • respiratory distress
  • vertex presentation
  • umbilical cord entanglement
  • fetal anomalies
  • male sex
  • increased birth weight

- gross placental features

  • increased placental weight
  • right-twisted cords
  • markedly twisted cords
  • true knots
  • congestion

- microscopic placental features

  • nucleated red blood cells
  • chorangiosis
  • placental vascular thrombi
  • placental vascular cushions
  • meconium
  • increased syncytial knots
  • single umbilical artery

- significantly increased risk of brain imaging abnormalities and/or abnormal neurological follow-up

- increased risk of a second long cord.

(Some of these histopathologic features have previously been associated with fetal hypoxia and/or altered blood flow in the placenta.)
