The morbidly adherent placenta is rare with an incidence of 0.3 /1000 deliveries in Dublin.Clinical suspicion very important as current modalities for prenatal diagnosis are limited.Currently almost 50% of cases are delivered as emergencies.There should be greater use of uterotonics as an adjunct to surgery.The efficacy and safety of surgical interventions and blood products need constant evaluation.Senior staff involvement critical.
