| Popis: | Objective Placenta accreta spectrum (PAS) is a condition defined by abnormal adherence of the placenta. Cesarean hysterectomy is the preferred management, but practice patterns vary based on local resources and expertise. We retrospectively reviewed the clinical course of patients diagnosed antenatally with PAS who underwent surgical management in our centre. Methods We conducted a retrospective records review involving patients with an antenatal diagnosis of PAS between 2014 and 2019. The primary outcome was a composite score of maternal morbidity, and secondary outcomes were total estimated blood loss and composite neonatal morbidity. Patients were stratified based on the presence or absence of PAS on final pathology. Antenatal diagnosis by ultrasound and magnetic resonance imaging (MRI) was compared with final histologic diagnosis. Results A total of 34 patients were diagnosed with PAS antenatally and managed at our institution. Final histology confirmed PAS in 29 patients. The overall composite morbidity rate was 44%, with no significant difference between patients with and without PAS on pathology (P = 0.355). Intraoperative blood loss was similar between the 2 groups (2374 ± 2212 mL vs. 1080 ± 852 mL; P = 0.232). The rate of composite neonatal morbidity was 47%. Ultrasound achieved a high positive predictive value in the diagnosis of PAS (96%) and more accurately predicted pathology than MRI. Conclusions PAS is associated with high rates of morbidity. Dissemination of our local experience serves to inform best practices in the management of this complex condition. |
