产前超声检查对妊娠晚期产科性出血病因的诊断价值

Application of ultrasound in etiological diagnosis of obstetric hemorrhage in late pregnancy

目的分析产前超声检查对妊娠晚期产科性出血病因的诊断价值。方法收集2014年7月至2017年10月锡山人民医院就诊的102例妊娠晚期产科性出血患者,均作产前超声诊断,并进行随访及病理检查,分析超声对妊娠晚期产科性出血患者的诊断价值,及对不同产科性出血病因的临床价值。结果超声对妊娠晚期出血病因诊断的灵敏度为97.9%,特异度为66.7%,正确指数为64.6%,阳性预测值为97.9%,阴性预测值为66.7%,ROC曲线下面积是0.823;超声对前置胎盘诊断的准确性最高(98.6%)。结论产前超声检查对妊娠晚期产科性出血病因的诊断价值较高,且对不同类型出血原因的诊断价值不同。

Objective To analyze the diagnosis value of ultrasound in etiological diagnosis of obstetric hemorrhage in late pregnancy. Methods 102 cases who were diagnosed obstetric hemorrhage in late pregnancy in Xishan People’s Hospital from July 2014 to October 2017 were collected, all received preoperative ultrasound diagnosis, and followed-up and histopathologically examined, analysis of the diagnostic value of ultrasound in patients with postpartum obstetric hemorrhage, and the diagnostic value of ultrasound in the etiology of different obstetric hemorrhage were analyzed. Results The sensitivity of ultrasound for the diagnosis of late pregnancy bleeding was 97.9 %, the specificity was 66.7 %, the correct index was 64.6 %, the positive predictive value was 97.9 %, the negative predictive value was 66.7 %, and the area under the ROC curve was 0.823;diagnosis of placental previa was the most accurate(98.6 %). Conclusion Prenatal ultrasound examination has a higher diagnostic value for the etiology of obstetric hemorrhage in late pregnancy, and has different diagnostic value for different types of bleeding.
