Analysis of risk factors and pregnancy outcome of placenta previa combined with penetrating placenta implantation
Objective To explore the risk factors and pregnancy outcomes of placenta previa combined with penetrating placenta implantation(PP).Methods A total of 369 pregnant women with placenta previa combined with PP admitted to the hospital for delivery via cesarean section from June 2019 to December 2022 were selected and divided into the unperforated group(297 cases)and the perforated group(72 cases)accord-ing to the clinical grading of placenta implantation.The pregnancy outcomes of pregnant women in the two groups were compared,and the risk factors for the occurrence of placenta previa combined with PP were ana-lyzed using logistic regression models.Results The percentage of pregnant women in the penetrated group with placement of abdominal aortic balloon,uterine tamponade(balloon/gauze),and hysterectomy,as well as the rates of intraoperative hemorrhage,post-partum complications,and adverse neonatal outcomes were signif-icantly higher than those in the non-penetrated group,and the differences were all statistically significant(P<0.05).Induced abortion clearance was a risk factor for PP combined with placenta previa(OR=2.421,95%CI 1.107-5.296,P=0.027).The number of previous cesarean sections≥1 was an independent risk factor for PP combined with placenta previa(OR=3.314,95%CI 1.525-7.203,P=0.002).Conclusion The rate of adverse outcomes in pregnant women with placenta previa combined with PP was high despite more aggressive perioperative measures to prevent bleeding.The number of previous cesarean sections≥1 is an independent risk factor for PP with placenta previa.
