Curative effect of cervical lifting suture combined with the improved Hayman suture in pernicious placenta previa under noninterventional conditions: A retrospective cohort study.

Abstract

To propose a novel operative strategy involving cervical lifting suture (CLS) in conjunction with the improved Hayman suture (CLS-Hayman) to apply in the cesarean section of pernicious placenta previa (PPP) under noninterventional conditions and evaluate the curative effect of the CLS-Hayman operation by comparing with conventional CLS. A retrospective cohort study was conducted on 119 pregnant women diagnosed with PPP, including 50 cases in the CLS-Hayman group and 69 cases in the CLS group. The authors used different statistical methods to compare intraoperative bleeding, 24-h postpartum bleeding, postoperative complication rates, and uterine involution between the two groups under noninterventional conditions. The median intraoperative blood loss was 800 mL in the CLS-Hayman group versus 1000 mL in the CLS group. The amount of 24-h postpartum bleeding in the CLS-Hayman group was lower than that in the CLS group. The complication rates in the two groups were 12% and 27.5%, respectively (P=0.04). B-ultrasound or magnetic resonance imaging data showed that the uterine involution was better in the CLS-Hayman group. The CLS-Hayman suture achieves the desired intraoperative hemostasis and also stands out for its better prevention of postpartum hemorrhage, better prognosis at follow-up, and lower complication rates.
