OBJECTIVE: To evaluate the common and severe maternal morbidities associated with medical termination of pregnancy (MTOP) for fetal anomaly ≥20 weeks' gestation.
METHODS: A 10-year retrospective cohort study (January 2010-December 2019) analyzing 407 consecutive singleton pregnancies MTOP for fetal anomaly ≥20 weeks' gestation, at a quaternary maternity centre in Australia (Royal Women's Hospital, Melbourne).
RESULTS: The cohort comprised of 191 primiparous and 216 multiparous women, of whom 75 (34.7%) had at least one prior Cesarean; 13 women had a low-lying placenta or placenta praevia. The average gestation was 23 weeks (interquartile range 22-26 weeks). A spontaneous unassisted vaginal delivery was achieved by the majority (n = 403, 99.0%). The most common maternal morbidities were transferred to the theater for manual removal of retained placental tissue (n = 65, 16.0%) and postpartum haemorrhage (PPH) (n = 45, 11.1%). Severe maternal morbidity occurred in six cases (1.3%) and included amniotic fluid embolism, cardiac arrest, major obstetric haemorrhage, uterine rupture and intensive care unit admission. There were no maternal deaths.
CONCLUSIONS: The most common complications of MTOP for fetal anomaly ≥20 weeks' gestation were manual removal of placenta and PPH. Severe maternal morbidity affected 1 in 81 women.
