摘要
目的研究产前超声诊断技术在胎儿先天性膈疝合并畸形中的应用价值与影像学表现。方法回顾性分析2010年11月至2018年11月,十堰市妇幼保健院收治的先天性膈疝合并畸形胎儿50例为试验组,同期孕检结果显示正常胎儿50例为对照组。2组患者均行产前超声诊断,对比2组影像学诊断结果中显示的脐动脉收缩末期与舒张末期血流峰值比值(S/D)、胸腔回声异常情况、心脏纵膈移位情况、分析先天性膈疝合并畸形胎儿产前超声诊断影像学结果与正常胎儿超声诊断影像学结果的区别。对比试验组引产或分娩前后产前超声诊断对先天性膈疝合并畸形的检出率与检验准确率,判断产前超声诊断在胎儿先天性膈疝合并畸形中的临床应用价值。结果2组脐动脉S/D比值比较,差异无统计学意义(P>0.05);试验组胸腔回声异常、心脏纵膈移位患者例数明显高于对照组,差异有统计学意义(P<0.05);试验组引产或分娩前产前超声诊断先天性膈疝合并畸形检出率与检验准确率与分娩或引产结果比较,差异无统计学意义(P>0.05)。结论胎儿先天性膈疝合并畸形其影像学表现包括大脑中动脉峰值流速明显降低、胸腔回声异常、心脏纵膈移位。此外,产前超声诊断技术在胎儿先天性膈疝合并畸形的诊断中检出率与检验准确率均较高,具有较高的应用价值。
Objective To study the application value and imaging manifestations of prenatal ultrasound diagnosis in congenital diaphragmatic hernia complicated with fetal malformation.Methods A retrospective analysis was performed on 50 fetuses with congenital diaphragmatic hernia combined with malformation admitted to Shiyan maternal and child health hospital from November 2010 to November 2018 as the experimental group,and 50 normal fetuses as the control group according to the pregnancy test results during the same period.Prenatal ultrasound diagnosis was performed in both groups,and the imaging findings of the two groups were compared with the peak flow velocity of the middle cerebral artery,the ratio of the peak blood flow at the end of umbilical artery contraction to the peak of the end of diastolic artery(S/D),the abnormal echoes in the thoracic cavity,and the displacement of the mediastinal heart.The detection rate and test accuracy of prenatal ultrasound diagnosis of congenital diaphragmatic hernia combined with malformation in the experimental group were compared before and after induction of labor or delivery,and the clinical application value of prenatal ultrasound diagnosis in fetal congenital diaphragmatic hernia combined with malformation was evaluated.Results There was no significant difference in S/D ratio between the two groups,and the results were not statistically significant(P>0.05).The number of patients with abnormal thoracic echo and cardiac mediastinal displacement in the experimental group was significantly higher than that in the control group,and the comparison results were statistically significant(P<0.05).The detection rate and test accuracy of prenatal ultrasound diagnosis of congenital diaphragmatic hernia combined with malformation in the experimental group were not statistically significant compared with the results of labor induction or labor induction(P>0.05).Conclusion The imaging findings of congenital diaphragmatic hernia with malformation include significantly reduced peak flow velocit
