【摘要】 目的分析妊娠中晚期胎儿复杂性先天性心脏畸形筛查中超声心动图的作用。方法选择2016年7月～2018年1月在江油市人民医院就诊的600例高危孕妇为研究对象,所有研究对象均行妊娠中晚期超声心动图检测,并将检测结果与产后病理结果进行对比,比较超声心动图检查的诊断准确性。结果 600名孕妇经彩色多普勒超声检查共检出复杂性先天性心脏畸形者23例,占3.83%;产后病理检查结果显示,研究对象中复杂性心脏畸形者共26例,占4.33%;两者检出率比较无统计学意义(P> 0.05),超声心动图筛查准确率为88.46%,且23例经超声检测出的畸形胎儿中,以法洛四联症为主,其次为右室双出口、完全性心内膜垫缺损等。经彩色多普勒超声检查显示为复杂性先天性心脏畸形23例患者中,胎儿内径增宽者9例,占39.1%,内径狭窄者7例,占30.4%,内径正常者7例,占30.4%。结论妊娠中晚期胎儿复杂性先天性心脏畸形筛查中应用超声心动图检查具有较高价值,可在临床上推广应用。更多还原

【Abstract】 Objective To analyze the role of echocardiography in the screening of complex congenital heart malformations in middle and late pregnancy. Methods From July 2016 to January 2018, 600 high-risk pregnant women admitted to Jiangyou People’s Hospital were selected as the study subjects. All the subjects underwent echocardiography in the middle and late pregnancy, and the test results were compared with the postpartum pathological results to compare the diagnostic accuracy of echocardiography. Results A total of 23 cases(3.83%) of 600 pregnant women with complex congenital heart malformation were detected by color doppler ultrasonography. Postpartum pathological examination showed that there were 26 cases of complicated cardiac malformation among the subjects, accounting for 4.33%.There was no significant difference in detection rate between the two group(P > 0.05). The accuracy of echocardiographic screening was 88.46%, and among 23 cases of abnormal fetuses detected by ultrasound, tetralogy of fallot was the main one, followed by right ventricular double outlet and complete endocardial cushion defect. Among the 23 patients with complex congenital heart malformation revealed by color doppler ultrasonography, 9 cases(39.1%) had wider fetal diameter, 7 cases(30.4%) had narrow diameter, and 7 cases(30.4%) had normal diameter. Conclusion The application of echocardiography in screening complicated congenital heart malformations of fetuses in middle and late pregnancy is of high value and can be popularized in clinical practice.更多还原
