What is Vasa Praevia?

  • Vasa praevia oocurs when one or more of the baby‘s placental or umbilical blood vessels cross the entrance to the birth canal beneath the baby.
  • When the cervix dilates or the membrane rupture, the unprotected vessels can tear, causing rapid fetal haemorrhage.
  • When the baby drops into the pelvis, the vessels can be compressed, compromising the baby’s blood supply and causing oxygen deprivation.
