目的探讨产前超声所示胎儿胃泡形态学变化在不同类型消化道畸形中的声像图特征及其临床价值。方法应用彩色多普勒超声检查妊娠13~42周胎儿,测量胃泡最长径、前后径、L/W比值,认真观察幽门部蠕动,节律性幽门管显示及有无幽门扩张等形态学变化,并与分娩后新生儿检查或胎儿尸体检查结果进行对照。结果产前超声共发现消化道畸形27例,其中先天性隔疝8例,十二指肠闭锁13例,空回肠闭锁4例,结肠闭锁2例。合并其他复杂畸形7例,羊水过多19例。结论胎儿胃泡形态学变化,特别是L/W比值、幽门部蠕动、节律性幽门管显示及有无幽门扩张,在消化道畸形中具有一定的特征性表现,有助于指导产科医生下一步处理。
Objective To investigate the characteristics and clinical value of fetal gas bubble morphological changes in prenatal ultrasound in different types of gastrointestinal malformations. Methods Fetal ultrasound was performed in 13 to 42 weeks gestation with color Doppler ultrasonography. The longest diameter, anterior and posterior diameter, L / W ratio were measured. The morphological changes such as pyloric peristalsis, rhythmic pyloric tube display and pyloric dilatation , And compared with the newborn examination after childbirth or fetal carcass examination results. Results Prenatal ultrasound found 27 cases of gastrointestinal malformations, including 8 cases of congenital hernia, 13 cases of duodenal atresia, 4 cases of ileal atresia and 2 cases of colon atresia. 7 cases complicated with other complex deformities, 19 cases of polyhydramnios. Conclusion Fetal gastric bubble morphological changes, especially the L / W ratio, pyloric peristalsis, rhythmic pyloric tube with or without pyloric dilatation, in the gastrointestinal malformations have a certain characteristic performance, help guide the obstetrician next step deal with.
