I am the lead developer of the Royal College of Gynaecologists’ Green-top guidelines on placenta previa and placenta accreta spectrum (PAS), referenced in your article (Campaign urges NHS to improve diagnosis of potentially life-threatening childbirth condition, 18 February). I also have personal experience of placental delivery complications, as when my son was born, his placenta got stuck inside the womb of his mother after his birth (placental retention).
Placental retention is due to the premature closure of the cervix after the birth of the baby, and is a leading cause of uterine atony and postpartum haemorrhage, affecting around one in 100 births.
