二维联合四维超声产前诊断胎儿畸形研究进展

Research progress of prenatal diagnosis of fetal malformation by two-dimensional combined with four-dimensional ultrasound

产前筛查至关重要,超声检查是产前筛查的基本途径,其在产前胎儿畸形的确诊工作中起到重要作用,不可忽缺。作为一种传统的诊断方式,二维超声具备简易性、无创性和反复操作性等优点。二维超声诊断法此前应用比较普遍,但临床研究发现此法有一定不足,无法准确诊断胎儿畸形。近年来,医学领域开始大范围尝试使用二维超声联合四维超声进行产前胎儿畸形的筛查工作,这种新技术为产前诊断胎儿畸形提供了更多方向。论文分析归纳了产前诊断胎儿畸形临床实践中二维、四维超声联用方案的应用概况,分析该领域的研究进展,为提升胎儿畸形检出的准确率及减少胎儿出生缺陷提供应用价值更高的诊断方法。

Prenatal screening is very important.Ultrasound examination isthe basic way of prenatal screening.It plays an important role in the diagnosis of prenatal fetal malformation and cannot be missing.As a traditionaldiagnostic method,two-dimensional ultrasonography has the advantages of simplicity,noninvasiveness and repeatability.Two-dimensional ultrasonography has been widely used in the past,but clinical studies have found that this method has some deficiencies,unable to accurately diagnose fetal malformations.In recent years,the medical field has started to try to use two-dimensional ultrasound combined with four-dimensional ultrasound to screen prenatal fetal malformations on a large scale,and this new technology provides more directions for prenatal diagnosis of fetal malformations.This paper analyzes and summarizes the general situation of the application of two-dimensional and four-dimensional ultrasonography combined in the clinical practice of prenatal diagnosis of fetal malformation,and analyzes the research progress in this field,so as to provide a diagnosticmethod with higher application value for improving the accuracy of fetal malformation detection and reducing fetal birth defects.
