Subsequent Pregnancy Outcome in Women with Prior Complete Uterine Rupture: A Single Tertiary Care Centre Experience

Limited data is available to assess the burden of maternal morbidity, mortality, and perinatal outcome after subsequent pregnancy in women with prior uterine rupture. Therefore, this retrospective descriptive study was conducted to determine subsequent pregnancy outcomes in a larger series of women with prior complete uterine rupture. All pregnant women who had complete uterine rupture were managed according to the standard Institute protocol. The women who conceived following a uterine repair from July 2011 to June 2020 were recruited into the study. Outcome measures included severe maternal morbidities and perinatal outcomes. Fifty-three women with prior complete uterine rupture were conceived subsequently. Two women had an abortion in the first and second trimester, respectively. None of the women developed recurrence of uterine rupture. However, three women developed uterine dehiscence in a total of 16 women who went into spontaneous labour before elective cesarean delivery at 32, 36, and 37 weeks, respectively. None of the women had placenta previa, placenta accreta, bowel injury, bladder injury and none required a hysterectomy. However, 16.7% of women needed a blood transfusion. None of the women required mechanical ventilation, inotropic support, and intensive care unit stay. Seventeen babies required neonatal intensive care admission, and prematurity (90%) was the most common reason, followed by low APGAR scores. In conclusion, subsequent pregnancy outcomes in women with prior uterine rupture appear acceptable in institutionalized care. Timing of cesarean delivery may have to be weighed against the risk of prematurity-associated neonatal morbidity and mortality.
