摘要 目的:探讨超声在妊娠晚期产科性出血病因诊断中的临床价值。材料与方法:收集来我科就诊的临床诊断为妊娠晚期产科性出血的患者96例,均采用超声进行检查,以临床和病理检查结果作为诊断的金标准,分析超声检查对妊娠晚期出血病因检查的临床价值,以及超声检查对不同产科性出血病因的临床价值,指标包括灵敏度、特异度、漏诊率、误诊率、阳性预测值、阴性预测值和正确指数。结果:超声检查对妊娠晚期出血病因诊断的灵敏度为97.8%,特异度为75.0%,阳性预测值为98.9%,阴性预测值为60.0%,ROC曲线下面积是0.864.超声对不同妊娠晚期产科性出血病因的临床诊断价值不全相同,对脐血管前置诊断的准确性最高,其误诊率和漏诊率均为0.0%,其次是前置胎盘,误诊率为0.0%,而漏诊率为4.0%,对胎盘早剥的漏诊率为0.0%,而误诊率较高为33.3%,对胎盘植入的误诊率为0.0%,然漏诊率较高为33.3%。结论:超声对妊娠晚期产科性出血病因诊断的临床价值较高,但不同病因的诊断价值不全相同。 Purpose: To explore the diagnosis value of ultrasonography in the diagnosis of obstetric hemorrhage in late pregnancy. Materials and Methods: 96 cases who were diagnosed obstetric hemorrhage in late pregnancy were collected, all were examined by ultrasonography, clinical and pathological examination results was regarded as the gold standard for diagno- sis, then analyzed the clinical value of uhrasonography in the etiology diagnosis of obstetric hemorrhage in late pregnancy, and analyzed the clinical value of ultrasonography in the etiology of different obstetric hemorrhage, the indexes included sensitivity, specificity, missed diagnosis rate, misdiagnosis rate, positive predictive value, negative predictive value and correct index. Results: The sensitivity of uhrasonography in the etiology diagnosis of obstetric hemorrhage in late pregnancy was 97.8%, the specificity was 75%, the positive predictive value was 98. 9%, the negative predictive value was 60%, the area under the ROC curve was 0. 864. The clinical value of ultrasound in the diagnosis of obstetric hemorrhage in different pregnancy was not identical, the diagnostic accuracy of the umbilical artery was the highest, the misdiagnosis rate and missed diagnosis rate were 0. 0 % ; followed by the placenta, the misdiagnosis rate was O. 0 %, and the rate of missed diagnosis was 4. 0 % ; for the pla- centa, the missed diagnosis rate was 0. 0 %, and the misdiagnosis rate was 33.3% ; the misdiagnosis rate of placenta implan- tation was 0.0 %, and the rate of missed diagnosis was 33.3%. Conclusion: The diagnosis value of uhrasonography in the diagnosis of obstetric hemorrhage in late pregnancy is high, and the clinical value of ultrasound in the diagnosis of obstetric hemorrhage in different pregnancy is not identical.
