More about Vasa praevia

The umbilical cord inserts into the surface membranes of the placenta rather than directly into the placenta (velamentous cord insertion).

Vasa praevia is a rare but important health problem that occurs when the blood vessels from the placenta or umbilical cord block the birth canal and tear during delivery.

The condition is associated with a number of risk factors:

  • The umbilical cord inserts into the surface membranes of the placenta rather than directly into the placenta (velamentous cord insertion)
  • An unusual shaped placenta eg in two pieces with blood vessels running between (bilobed and succenturiate placenta)
  • Low-lying placenta or placenta praevia pregnancies resulting from in-vitro fertilisation
  • Multiple pregnancies
