目的:探讨中孕期胎儿系统超声检查切面及临床意义。方法:选取进行产前检查的10000例中孕期孕妇作为研究对象,所有孕妇均在中孕期进行过9切面和32切面系统的超声检查,回顾分析其临床资料与超声检查结果,观察比较2种方法筛查出胎儿畸形的情况。结果:有62例孕妇的胎儿存在不同程度和类型的畸形,并且在产后或引产后得到证实。两种方法筛查中孕期孕妇胎儿畸形情况比较,32切面超声检查较9切面超声检查更为敏感和准确,两种方法比较差异显著,有统计学意义(p<0.05)。结论:中孕期进行9切面和32切面系统的超声检查都能够较好的检出胎儿畸形,但32切面系统的超声检查的敏感性更高,值得在临床上得到进一步的推广应用。
Objective: To investigate the ultrasound section and its clinical significance of fetal system in the second trimester. Methods: A total of 10 000 pregnant women of prenatal period were enrolled in this study. All pregnant women underwent ultrasound examination on 9 and 32 incision systems in the second trimester. The clinical data and ultrasound findings were retrospectively analyzed. Two methods were compared Screening for fetal malformations. Results: There were 62 fetuses with different degrees and types of malformations, which were confirmed after delivery or after labor. Comparing the fetal malformations of pregnant women during the two screening methods, the 32-slice ultrasound was more sensitive and accurate than the 9-slice ultrasound examination. There was significant difference between the two methods (p <0.05). CONCLUSION: Ultrasound examination of 9-slice and 32-slice systems during the first trimester can detect fetal malformations better. However, ultrasonography of 32-slice system is more sensitive and deserves further clinical application.
