基于产前胎儿及附属物超声征象构建胎盘植入性疾病妊娠不良结局的风险预测模型
Construction of risk prediction model based on ultrasound signs of prenatal fetal and accessory for adverse pregnancy outcomes of patients with placental implantation disease
摘要
Abstract
Objective:To construct a risk prediction model based on ultrasound signs of prenatal fetal and accessory for adverse pregnancy outcomes of patients with placental implantation disease.Methods:This study is a prospective study.A total of 120 pregnant women who underwent hospital delivery in Tangshan maternal and child health care hospital from January 2022 to June 2023 were selected as the research objects,including 39 cases with placenta implantation and 81 cases without placenta implantation.The cases with placenta implantation were divided into adverse pregnancy group(19 cases)and good pregnancy group(20 cases)according to the different pregnancy outcome.The placental location,posterior low gyrus vocal cords of placenta,placental multiple lacunae,basal blood vessels,bladder line,and cervical sinusoids of all cases were compared.Logistic multivariate analysis was adopted to verify and construct the risk model of placenta implantation and adverse pregnancy outcomes.Results:There was significant difference in placental thickness between the cases with placenta implantation[(37.26±0.52)cm]and the cases without placenta implantation[(36.02±0.25)cm](t=14.127,P<0.05).There were significant differences between the two groups in the placenta location,posterior low gyrus vocal cords of placenta,placental multiple lacunae,basal blood vessels,bladder line and cervical sinusoids(x2=4.061,5.112,8.381,4.771,17.021,32.341,P<0.05),respectively.There was significant difference in placental thickness between the adverse pregnancy group[(36.85±0.42)cm]and the good pregnancy group[(37.45±0.24)cm](t=5.440,P<0.05).There were statistically significant differences between the two groups in the cases number of placenta location,posterior low gyrus vocal cords of placenta,placental multiple lacunae,basal blood vessels,bladder line and cervical sinusoids(x2=6.037,6.041,11.351,6.741,12.321,13.552,P<0.05),respectively.The results of multivariate analysis indicated that placental thickness,placenta location,posterior low gyrus vocal cords of placenta,placental multiple lacunae,basal blood vessels,bladder line and cervical sinusoids were the risk factors for placenta implantation of pregnant women(OR=3.300,3.374,2.995,3.384,2.843,2.878,3.053,P<0.05),respectively.Placental thickness,placenta location,posterior low gyrus vocal cords of placenta,placental multiple lacunae,basal blood vessels,bladder line and cervical sinusoids were respectively the risk factors that caused adverse pregnancy outcomes for pregnant women(OR=2.821,2.886,3.287,3.377,2.942,3.177,3.168,P<0.05).The result of receiver operating characteristic(ROC)curve indicated that the area under curve(AUC)values of the above model for placenta implantation and adverse pregnancy outcome were larger than 0.700.Conclusion:The prediction based on the model of ultrasound signs of prenatal fetal and accessory is more accurate,which can be used as important reference in clinically early diagnosis.关键词
