Placenta Accreta Spectrum: A 2-year Retrospective Observational Study

Aims To assess the management and outcomes of Placenta Accreta Spectrum disorders and highlight the important management recommendations from international guidelines. Methods A retrospective audit of women diagnosed with Placenta Accreta Spectrum disorder from January 2018 to December 2019. Results Nine cases (0.16%) of placenta accreta from 5695 births were identified. All women received caesarean section under general anaesthesia. Caesarean hysterectomy occurred in seven cases (78%). Mean (±SD) age of women was (34.4 ± 3.9 years) and mean parity score was (3.2 ± 1.2). Mean gestational age at birth was 35.1 ± 0.8 weeks. Bilateral iliac artery balloon occlusion occurred in eight (89%) cases. Median estimated blood loss [range] was 1700 mL [1000-7000] with only 11% of patients (1/9) experiencing more than 3L of blood loss. Intraoperative red blood cell transfusion occurred in six cases (67%). Median number of units of red cell transfusion [range] was four units [0-10]. Mean hospital length of stay was (6.7 ± 1.1 days) and there were no maternal deaths. Multidisciplinary team involvement of senior anaesthetists and obstetricians was noted in all cases. Discussion Placenta accreta spectrum is increasing in incidence in obstetric practice and is associated with significant maternal morbidity and mortality. Implementing national guidelines can improve patient outcomes.
