Objective To explore the clinical value of multidisciplinary team (MDT)diagnosis and treatment mode in improving the maternal and fetal outcomes of placental previa with placental implantation.Methods A retrospective analysis was conducted on the clinical data of 281 patients with placenta previa and placental implantation who delivered at Jiangxi Maternal and Child Health Hospital from January 2017 to December 2022.According to whether MDT was performed before cesarean section,there were 152 cases in the MDT group and 129 cases in the non-MDT group.The diagnostic accuracy of placenta accreta site before cesarean section,preoperative pretreatment,and maternal and fetal pregnancy outcomes were compared between the two groups.Results The preoperative diagnosis coincidence rate of placenta implantation site in the MDT group was higher than that in the non-MDT group,the abdominal aortic balloon occlusion rate and ureteral catheterization rate in the MDT group were higher than those in the non-MDT group,and the intraoperative blood loss,bleeding＞2 000 ml rate,red blood cell transfusion volume and hysterectomy rate in the MDT group were lower than those in the non-MDT group,and the differences were statistically significant (P＜0.05).Conclusion MDT diagnosis and treatment mode can improve the accuracy of preoperative diagnosis of placenta previa with placenta accreta,help surgeons to develop individualized and precise treatment plans,and effectively reduce the amount of intraoperative blood loss,blood transfusion and reduced hysterectomy rate in patients with placenta accreta,which has certain clinical value in improving the pregnancy outcome of mother and child.
