| 摘要 目的：分析与探讨心脏超声在卵圆孔血流受限胎儿中的筛查价值。方法：2019年1月-2020年9月在本院进行产前心脏超声筛查的孕妇58例，都给予常规超声与组织多普勒成像，记录影像学特征并判断诊断价值。结果：58例胎儿判断为卵圆孔处血流受限18例，占比31.0 %。受限组的卵圆孔大小、卵圆瓣长度、继发隔长度都少于未受限组(P<0.05)。受限组的D-FOC值低于未受限组(P<0.05)，Vm-PV、Vm-FOC值高于未受限组(P<0.05)。受限组的左心室E、A、E'、A'值都低于未受限组(P<0.05)。结论：心脏超声作为检出胎儿心脏畸形的有效手段，可通过观察胎儿卵圆孔血流频谱与形态来鉴别诊断卵圆孔血流受限，是孕期诊断卵圆孔血流受限的最有效方法之一。 |

| ABSTRACT Objective: To analysis and explore the values of cardiac ultrasound in screening fetuses with restricted foramen blood flow. Methods: A total of 58 pregnant women, who underwent prenatal cardiac ultrasound screening in Northwest Women and Children's Hospital from January 2019 to September 2020, were given conventional ultrasound and tissue Doppler imaging. Their imaging characteristics were recorded and the diagnostic value was determined. Results: Among the 58 feti, there were 18 cases of restricted blood flow at the foramen ovale, accounting for 31.0 %. The size of the foramen ovale, the length of the oval valve, and the length of the secondary septum in the restricted group were less than those in the unrestricted group (P<0.05). The D-FOC value of the restricted group was lower than that of the unrestricted group (P<0.05), and the Vm-PV and Vm-FOC values were higher than those of the unrestricted group (P<0.05). The left ventricle E, A, E', A' values of the restricted group were lower than those of the unrestricted group (P<0.05). Conclusion: Cardiac ultrasound is an effective means to detect fetal heart malformations. It can be used to differentiate and diagnose foramen ovale blood flow limitation by observing the blood flow spectrum and morphology of the foramen ovale, which is one of the most effective methods to diagnose foramen ovale blood flow limitation during pregnancy. |
