Timing of delivery in placenta accreta

Fetal and maternal outcomes of segmental uterine resection in emergency and planned placenta percreta deliveries

OBJECTIVE

This study evaluated maternal and fetal outcomes of emergency uterine resection versus planned segmental uterine resection in patients with placenta percreta (PPC) and placenta previa (PP).

METHODS

Patients with PP and PPC who underwent planned or emergency segmental uterine resection were included in this study. Demographic data, hemorrhagic morbidities, intra- and postoperative complications, length of hospital stay, surgical duration, and peri- and neonatal morbidities were compared.

RESULTS

A total of 141 PPC and PP cases were included in this study. Twenty-five patients (17.73%) underwent emergency uterine resection, while 116 (82.27%) underwent planned segmental uterine resections. The postoperative hemoglobin changes, operation times, total blood transfusion, bladder injury, and length of hospital stay did not differ significantly between groups (P=0.7, P=0.6, P=0.9, P=0.9, and P=0.2, respectively). Fetal weights, 5-minute Apgar scores, and neonatal intensive care unit admission rates did not differ significantly between groups. The gestational age at delivery of patients presenting with bleeding was lower than that of patients who were admitted in active labor and underwent elective surgery (32 weeks [95% confidence interval [CI], 26-37] vs. 35 weeks [95% CI, 34-35]; P=0.037).

CONCLUSION

Using a multidisciplinary approach, this study performed at a tertiary center showed that maternal and fetal morbidity and mortality did not differ significantly between emergency versus planned segmental uterine resection.

Emergent versus planned delivery in patients with placenta accreta spectrum disorders: A retrospective study

ABSTRACT

The aim of this study is to compare the clinical outcomes and to identify risk factors for emergent cesarean delivery and planned cesarean delivery in patients with placenta accreta spectrum (PAS) disorders in Vietnam.The medical records of patients admitted to our hospital with a diagnosis of PAS disorders >5 years were retrospectively reviewed.A total of 255 patients with PAS disorders were identified, including 95 cases in the emergent delivery group and 160 cases in the planned delivery group. The percentage of complete/partial placenta previa in the planned delivery group was significantly higher than that in the emergent delivery group (59.22% vs 32.16%, P = .027). Fewer patients in the planned group had vaginal bleeding compared with those in the emergent group (29 vs 36 cases, P < .001). The percentage of blood transfusion was similar between the 2 groups; however, the transfused units of pack red blood cells were greater in the emergent delivery group (5.3 ± 0.33 vs 4.5 ± 0.25 U, P = .036). When considering the neonatal outcomes, the data demonstrated that the planned delivery group had a significantly higher birth weight and a lower rate of preterm delivery than the emergent group (P < .001). The mean gestational age at delivery for the emergent group was 35.1 ± 0.27 weeks compared with 38.0 ± 0.10 weeks for the planned group (P < .001). The increased risk factors for emergent delivery were vaginal bleeding (odds ratio 2.86, 95% confidence interval 1.59-5.26) and preterm delivery (odds ratio 5.26, 95% confidence interval 2.13-14.29).Planned delivery is strongly associated with a lower need for blood transfusion and better neonatal outcomes compared with emergent delivery. Antenatal vaginal bleeding and preterm labor are risk factors for emergent delivery among patients with PAS disorders. Based on the results of this study, we recommend that the management strategies for patients with PAS disorders should be individualized to determine the optimal timing of delivery and to decrease the rate of emergent cesarean delivery.
