胎盘植入程度的超声临床评价分析

Study on ultrasound score of placenta accreta

目的探讨超声评分用于胎盘植入程度评估的应用价值。方法收集2014年2月~2016年12月我院产科分娩的、产后经临床和/或病理证实为胎盘植入患者82例的临床资料。根据胎盘植入类型分为粘连型组26例和非粘连型组56例。采用本文建立的超声评分系统进行分析。结果非粘连型组超声评分显著高于粘连型组(P<0.05)。按超声评分系统计算粘连型组和非粘连型组中各孕妇总得分并绘制ROC曲线。曲线下面积为0.934,当评分≥5.2时,敏感度为0.856,特异度为0.938。粘连型胎盘植入和非粘连型胎盘植入的超声评分临界值为5分。结论产前应用本文所建立的超声评分系统用于胎盘植入程度的评估,具有很好的特异性和敏感度,其应用前景良好。

Objective To evaluate the value of ultrasonography in the evaluation of placenta accreta.Methods The clinical data of 82 patients with placenta accreta were confirmed by clinical and / or pathologic examination in our hospital from February 2014 to December 2016.According to placenta accreta type, those were divided into adhesive group of 26 cases and non-adhesive group of 56 cases.The ultrasound grading system established in this paper was used for analysis.Results The ultrasonographic score of the non-adhesive group was significantly higher than that of the adhesive group （P〈0.05）.The total score of the pregnant women in the adhesive group and the non-adhesive group was calculated by the ultrasound score system and the ROC curve was plotted.The area under the curve was 0.938, when the score was ≥5.2, the sensitivity was 0.856 and the specificity was 0.938.The critical score of the ultrasound score of adhesive placenta accreta and nonadhesive placenta was 5 points.ConclusionThe prenatal application of the ultrasound scoring system established in this paper for the evaluation of placental implantation, has good specificity and sensitivity, and its application prospects are good.
