中孕期胎儿肺动脉发育异常的超声心动图诊断价值

Value of echocardiography in diagnosis of fetal pulmonary artery dysplasia during second trimester

目的:探讨胎儿超声心动图诊断中孕期胎儿肺动脉及其分支异常的诊断价值。方法:回顾性分析2018年1月至2020年12月期间在我院筛查的胎儿肺动脉及其分支畸形,总结分析其各种类型的胎儿超声心动图特征并进行分析。结果:14008例胎儿中,共检出胎儿肺动脉及其分支异常72例,发生率为0.51%(72/14008),其中肺动脉狭窄51例(51/72,70.8%),肺动脉闭锁19例(19/72,26.4%),肺动脉吊带2例(2/72,2.8%)。结论:掌握肺动脉及其分支正常和异常胎儿超声心动图像的特征可有效并快速诊断各种类型的胎儿肺动脉畸形,具有重要临床意义。

Objective:To explore the diagnostic method and significance of fetal echocardiography in the diagnosis of fetal pulmonary artery and its branches abnormalities during second trimester.Methods:Retrospective analysis was done about the fetal pulmonary artery and its branches abnormalities screened in our hospital from January 2018 to December 2020,and the characteristics of various types of fetal echocardiography were summarized and analyzed statistically.Results:In this study,72 cases with abnormal pulmonary artery and its branches were detected in 14008 fetuses.The incidence rate was 0.51%(72/14008),including 51 cases of pulmonary artery stenosis(51/72,70.8%),19 cases of pulmonary artery atresia(19/72,26.4%)and 2 cases of pulmonary artery sling(2/72,2.8%).Conclusion:It is of great clinical significance to master the characteristics of normal and abnormal fetal echocardiography of pulmonary artery and its branches,which can help diagnose various types of fetal pulmonary artery malformation effectively and more quickly.
