摘要
目的:分析四腔心切面所见异常在产前超声诊断先天性心脏畸形中的作用和临床意义。方法:据四腔心切面所见异常对产前超声诊断先天性心脏畸形所提供的心脏信息及对诊断意义的不同,将产前超声诊断的先天性心脏畸形胎儿病例71例分为3组。结果:第1组为根据四腔心切面所见异常即可明确诊断的胎儿先天性心脏畸形,共52例,占73.24%,但该组伴发的大动脉畸形25例,占48.08%,如果单用四腔心切面将全部漏诊;第2组为根据四腔心切面所见异常可以提供存在先天性心脏畸形重要线索,共12例,占16.90%;第3组为四腔心切面所见基本正常,但存在先天性心脏畸形,共7例,占9.86%。71例中合并心外畸形的病例39例,占54.93%。结论:四腔心切面在产前超声筛选新生儿先天性心脏畸形方面具有非常重要的作用和临床意义,90%以上的先天性心脏畸形在四腔心切面上或多或少有异常特征,但有局限性,大动脉畸形漏诊相当常见,如果能加上左、右心室流出道等切面则明显减少漏诊。
Objective:To evaluate the clinical significance and effect of the anomalies seen at the four-chamber view antenatally in diagnosis of fetal congenital cardiac malformation. Methods:Seventy-one cases with congenital cardiac malformation(s) were diagnosed on prenatal ultrasonography. These cases were divided into three groups according to the difference of provided clinical diagnostic significance for antenatal diagnosis of fetal congenital cardiac malformations based on the anomaly seen on the four-chamber view. Results:Fifty two cases (73.24%) in group 1 could be diagnosed definitely or partially according to the features seen on the four- chamber view, but all the large vessels malformations 25 cases (48% )in this group were missed diagnosis if only using the four-chamber view. Twelve cases (16.90%) in group 2 presented important clues which may obviously suggest the presence of some diseases on the four- chamber view. Seven cases(9.86%) in group 3 showed normal features on the four- chamber view, although they carry the disease in each. In the mean time, 39 cases (54.52%) were found incorporating extracardiac malformations in the 71 case. Conclusion:It had real important clinical significance and effect that using four-chamber view antenatally ultrasonography screening be done for fetal congenital cardiac malformation. The majority of congenital heart anomalies (over than 90%) could be demonstrated abnormal configurations at four-dimensional view by various levels, although it is frequently less sensitivity to identify aortic and pulmonary malformations.
