产前超声诊断胎儿消化道畸形29例临床分析

Clinical analysis of 29 cases of fetal digestive tract malformation diagnosed prenatally by ultrasound

目的 探讨产前超声检查诊断胎儿消化道发育畸形的临床意义。方法 对孕期30~32周于本院检查出存在先天性消化道发育畸形的29例胎儿根据超声图像的不同特点进行分类分析,探讨其不同超声表现。结果 29例中无胃泡或小胃泡11例（37.93%）,合并多发畸形4例,合并羊水过多9例。管扩张、肠管多囊泡有7例（24.14%）,其中合并多发畸形3例,羊水过多3例。双泡征有8例（27.58%）,其中合并多发畸形1例,羊水过多7例。另3例无明显超声影像特征。结论 30~32周胎儿进行产前超声检查对发现胎儿消化道发育畸形有很高的诊断价值,值得在临床推广应用。

Objective To investigate the clinical significance of prenatal ultrasound examination in the diagnosis of fetal digestive tract development. Methods Twenty-nine cases of congenital digestive tract malformation were examined in according to the different characteristics of their different fetal ultrasound images. Results There were 11 cases with non-magenblase or less magenblase （37.93%）, 4 cases with combination of multiple malformations, and 9 cases with combination of amniotic fluid in the 29 cases. There were 7 cases （24.14%） with dilatation of intestine and intestinal vesicles, in which 3 with multiple malformations and 3 with polyhydramnios. There were 8 cases （27.58%） with double bubbles, in which 1 case with multiple malformations and 7 cases with amniotic fluid. Conclusion The prenatal ultrasound examination in 30 to 32 weeks of pregnancy is very valuable in diagnosis of fetal digestive tract development, which is worthy of clinical application.
