Placenta praevia and scarred uterus - an obstetrician's dilemma.

Three cases are presented here of patients who had placenta praevia following a previous caesarean section. All three patients had placenta accreta and developed severe postpartum haemorrhage necessitating total abdominal hysterectomy. We highlight the importance of being aware of the probability of severe haemorrhage due to placenta accreta in patients with placenta praevia following a previous caesarean operation.
