Objective To create a model for prediction of success of uterine‐preserving procedures in women with placenta accreta spectrum (PAS). Methods PAS‐ID is a multicenter study that included 11 centers from 9 countries. Women with PAS, who were managed between January 1, 2010 and December 31, 2019, were retrospectively included. Data were split into model development and validation cohorts, and a prediction model was created using logistic regression. Main outcome was success of uterine preservation. Results Out of 797 women with PAS, 587 were eligible. Uterus‐preserving procedures were successful in 469 patients (79.9%). Number of previous cesarean sections (CS) was inversely associated with management success (adjusted odds ratio [aOR] 0.02, 95% confidence interval [CI] 0.001–3.63 with five previous CS). Other variables were complete placental invasion (aOR 0.14, 95% CI 0.05–0.43), type of CS incision (aOR 0.04, 95% CI 0.01–0.25 for classical incision), compression sutures (aOR 2.48, 95% CI 1.00–6.16), accreta type (aOR 3.76, 95% CI 1.13–12.53), incising away from placenta (aOR 5.09, 95% CI 1.52–16.97), and uterine resection (aOR 102.57, 95% CI 3.97–2652.74). Conclusion The present study provides a prediction model for success of uterine preservation, which may assist preoperative and intraoperative decisions, and promote incorporation of uterine preservation procedures in comprehensive PAS protocols.

Extracorporeal membrane oxygenation (ECMO) is commonly used in patients who experience circulatory arrest or significant cardiac dysfunction and is associated with improved clinical outcomes. We conducted a retrospective observational study on ECMO application at a single tertiary center over a five-year period. Five patients who suffered post-partum hemorrhage resulting from uterine atony were treated with ECMO. The mean age was 36.8 ± 3.9 years; the mean gestational age was 37.8 ± 2.2 weeks; the initial mean maternal hemoglobin level was 5.0 ± 2.4 mg/dL; and the mean estimated blood loss was 3260 ± 1545 mL before treatment. All patients were treated with venoarterial ECMO and one was treated with both venoarterial and venovenous ECMO. The mean ECMO usage duration was 32.6 ± 18.8 h (range 10-54). Four (80%) patients survived until discharge without experiencing neurological sequela. ECMO should not be a contraindication for treatment of post-partum hemorrhage and such patients should be weaned as soon as possible to ensure the early recovery of cardiac function.
