Introduction: Placenta accreta spectrum (PAS) covers a spectrum of placental adherence abnormalities: placenta accreta, increta and percreta. PAS is associated with significant maternal morbidity and mortality. Studies have shown the importance of multidisciplinary teamwork in the management of PAS. Aim: This study was designed to describe the maternal and neonatal morbidity and mortality associated with PAS in our centre over a ten-year period. Methods: A retrospective cohort study was conducted of pregnancies complicated by PAS between February 2006 and January 2016 at Flinders Medical Centre (FMC), South Australia. Electronic and medical records were examined to obtain patient demographics, antenatal and surgical, findings and postnatal outcomes. Results: There were 67 PAS cases with an overall incidence of 2.3 per 1000 deliveries. Three cases were excluded due to incomplete information. Of the remaining 64 cases, 56 women were antenatally diagnosed. Sixty cases were confirmed to be invasive at delivery; 28 accreta (superficial) and 32 increta/percreta (deep) cases. The four cases with no invasion at delivery were suspected antenatally to have PAS. The median (Q1, Q3) number of caesarean sections in this cohort was 2 (1, 3). Deep invasion is significantly associated with increased bleeding, intensive care unit admission, surgical complications and an extended postpartum stay. Conclusion: The incidence of PAS at FMC is high as it is the state's tertiary referral centre. While PAS is associated with increased morbidity, thorough perioperative planning by a multidisciplinary team is crucial for excellent patient outcomes.
