【摘要】：目的探讨STIC技术在测量中孕期胎儿卵圆孔面积中的应用价值,初步建立正常参考值范围并且研究卵圆孔形态及卵圆孔周边结构在三维超声下的超声表现。方法选取在我院进行胎儿畸形筛查的孕妇250例,孕20~24周。在胎儿心脏条件下以四腔心为初始切面进行STIC容积数据采集,通过图像后处理,显示卵圆孔及其周围结构并测量卵圆孔最大面积。结果 250例胎儿中192例胎儿卵圆孔STIC数据重建成功。在孕20~24周,卵圆孔面积随孕周增大而增大,与孕周呈正相关。卵圆孔的形态分为圆形、椭圆形及不规则形。卵圆孔周围结构,如上腔静脉、下腔静脉、冠状静脉窦及三尖瓣等结构及相互空间位置关系可显示。结论 STIC技术测量卵圆孔面积可行;在孕20~24周,卵圆孔面积随孕周增大而不断增大;STIC技术可观察卵圆孔形态及于周围结构的空间关系;监测卵圆孔面积可对卵圆孔提前关闭或卵圆孔过大等提供依据。
[Abstract]:Objective to explore the application value of STIC technique in measuring the area of fetal foramen ovale during pregnancy, to establish the normal reference range and to study the shape of the foramen ovale and the appearance of the circumferential structure of the foramen ovale under three-dimensional ultrasound. Methods 250 pregnant women who were screened for fetal malformation in our hospital were selected for 24 weeks gestation. Under the condition of fetal heart, the volume data of STIC were collected with four cavities as the initial section. The structure of the foramen ovale and its surrounding structure were displayed and the maximum area of the foramen ovale was measured by image post-processing. Results the STIC data of the foramen ovale of 192 fetuses were reconstructed successfully. At the 24th week of gestation, the area of the foramen ovale increased with the increase of gestational week, which was positively correlated with the gestational week. The shape of the foramen ovale is divided into circular, elliptic and irregular shape. The structures around foramen ovale, such as superior vena cava, inferior vena cava, coronary sinus and tricuspid valve, etc. Conclusion it is feasible to measure the area of foramen ovale by STIC technique, and at the 24th week of gestation, the area of foramen ovale increases with the increase of gestational week, and the shape of foramen ovale and the spatial relationship between the foramen and the surrounding structure can be observed by STIC technique. Monitoring the area of the foramen ovale can provide the basis for the early closure of the foramen ovale or the oversize of the foramen ovale.
