Abstract:ObjectiveTo explore the value of ultrasound score combined with medical history for predicting the risk degree of pernicious placenta previa.MethodsClinical data of 58 patients with pernicious placenta previa treated in obstetrics department of our hospital and given terminal pregnancy from May to December 2017 were retrospectively analyzed.Prenatal diagnosis of pernicious placenta previa and placenta accrete was performed according to the ultrasound score scale combined with medical history score.The coincidence rate of the diagnosis,the sensitivity,and the specificity were evaluated after operation.At the same time,the receiver operating characteristic curve(ROC curve)was plotted and the area under the curve (AUC)was calculated.The cut-off score for each type of placenta accrete was calculated.ResultsAll patients were considered as pernicious placenta previa before surgery.Postoperatively,according to the ultrasound scoring combined with medical history,the coincidence rate of the diagnosis of pernicious placenta previa and placenta accreta,the sensitivity,and the specificity was 93.1%(54/58),94.5%(52/55),and 66.7%(2/3)respectively.According to the ROC curve,AUC of the adhesion type and the implant type was 92.5%.The corresponding value of the maximum index was 7.5 points,and the sensitivity and specificity was 76.9%and 84.6%respectively.Therefore,the boundary value of the adhesions and implants was 8 points.AUC of the implants and penetrating was 92.7%,and the corresponding value of the largest one was 11.5 points,and the sensitivity and specificity was 89.5%and 81.8%respectively.Therefore,the boundary value of the implants and penetrating types was 12 points.ConclusionFor pregnant women who are suspected to the pernicious placenta previa during the third trimester,ultrasound score combined with medical history can be used to predict the degree of risk before delivery.So,it can make the corresponding treatment plans in advance,to improve the quality of maternal and child perinatal life as much as possible.
