Maternal and neonatal outcomes following abnormally invasive placenta: a population-based record linkage study.
Abnormally invasive placenta involves abnormal adherence of the placenta to the myometrium and is associated with severe pregnancy complications such as blood transfusion and hysterectomy. Knowledge of outcomes has been limited by small sample sizes and a focus on maternal rather than neonatal outcomes. This study uses population-level data collected over 10 years to investigate maternal and neonatal outcomes and trends in incidence of abnormally invasive placenta (also known as placenta accreta, increta and percreta). ⋯ Abnormally invasive placenta substantially increases the risk of severe adverse outcomes for mothers and babies, and the incidence is increasing. Delivery should occur in tertiary hospitals equipped with neonatal intensive care units. Clinicians should be cognizant of the risks, particularly to infants, and maintain a high index of suspicion of abnormally invasive placenta, including in primiparae.
