Vasa Praevia
What is Vasa Praevia?
- Vasa Praevia occurs when one or more of the baby’s placental or umbilical blood vessels across the entrance to the birth canal beneath the baby.
- When the cervix dilates or the membranes 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.
