目的:探讨应用普通腹部B超广泛性筛查胎儿先天性心脏病的可行性及临床价值。方法:应用普通腹部B超通过多切面观察胎心大体形态、房室结构、房室瓣开闭、“十字交叉”完整性及主、肺动脉与心室连接情况等明显标志,筛查明显的胎儿先天性心脏病。异常者经彩超复查并送其他合作医院或省级权威部门再次做彩超检查、确认,并追踪至胎儿引产或出生后,取得尸解或心脏彩超结果。结果:筛查基本上能获得较满意的胎儿心脏二维声像,胎心结构清楚。总共发现单心室、心内膜垫缺损及三尖瓣闭锁并大动脉转位等严重的胎儿先天性心脏病16例。所有病例均能观察到较明显的相应的结构改变的二维声像。发现两例“假阴性”病例,可能与早期经验不足有关。未出现真的“假阳性”病例。结论:应用普通腹部B超检查广泛性筛查胎儿先天性心脏病是可行的,对提高胎儿先天性心脏病的检出率及支持优生优育政策的推行有着重大意义。
Objective: To investigate the feasibility and clinical value of general abdominal ultrasound screening for fetal congenital heart disease. Methods: General abdomen was used to observe the general form of fetal heart shape, the atrioventricular structure, atrioventricular valve opening and closing, the integrity of “cross” and the main signs of pulmonary artery and ventricular connection, Sexual heart disease. Abnormal by color Doppler ultrasound and sent to other partner hospitals or provincial authorities again to do color Doppler ultrasound examination, confirmed, and tracked to the fetus induced labor or after birth, acquired autopsy or cardiac ultrasound results. Results: Screening can basically get a more satisfactory two-dimensional fetal heart imaging, fetal heart structure clear. A total of 16 cases of severe fetal congenital heart disease, including single ventricle, endocardial cushion defect, and tricuspid valve atresia and aortic transposition were found. All cases can be observed more obvious corresponding structural changes in two-dimensional audio. Two cases of “false negatives” were found, which may be related to the lack of early experience. No real “false positive” cases have been reported. Conclusion: It is feasible to use general abdominal B-ultrasound to screen fetal congenital heart diseases extensively. It is of great significance to improve the detection rate of fetal congenital heart disease and to support the implementation of prenatal and postnatal care policies.
