Uterine Preservation and Maternal Outcomes Across FIGO Severity in Placenta Accreta Spectrum: A Six-Year Retrospective Cohort in Vietnam

Background/Objectives: Uterus-preserving management of placenta accreta spectrum (PAS) is increasingly reported, but preservation rates are difficult to interpret without considering disease severity and maternal morbidity. We aimed to estimate short-term uterine preservation through hospital discharge and describe maternal outcomes by FIGO clinical severity.

Methods

We conducted a retrospective single-center cohort study of 291 women with clinically diagnosed PAS and intraoperative FIGO grading who underwent cesarean delivery at Hung Vuong Hospital, a tertiary maternity referral hospital in Vietnam, from 2019 to 2024. The primary outcome was short-term uterine preservation through hospital discharge, defined as no hysterectomy during the index operation or before discharge. Secondary and exploratory analyses described hemorrhage and maternal morbidity across FIGO severity.
