摘要
目的:分析胎儿畸形的产前超声征象特点及其诊断价值。方法:回顾性分析2018年1月至12月本院产前超声检查结果,统计胎儿畸形检出情况,对比引产或产后复查结果,分析畸形胎儿的产前超声征象特点及产前超声漏诊畸形胎儿的特点。结果:15863例进行产前结构检查的胎儿中,421例胎儿经引产或产后复查证实为畸形,其中胎儿膈疝61例、胼胝体发育不良14例、消化道梗阻45例、肺囊腺瘤104例、隔离肺48例、多囊性肾发育不良69例、肾积水80例,畸形发生率为2.65%;产前超声检出率为94.06%,已知漏诊率为5.94%,产前超声诊断结果与引产或产后复查情况对比,差异无统计学意义(P>0.05)。漏诊原因主要有形态改变微小、检查时孕周太小和胎儿活动等。结论:畸形胎儿大多都有特征性的超声征象,产前超声对畸形胎儿,尤其对于形态学改变较大的畸形胎儿诊断价值较高,孕妇在不同孕期可进行多次超声检查以提高检出率。
Objective:To analyze the prenatal ultrasonographic features and its diagnostic value in fetal malformation.Methods:A retrospective analysis was performed on prenatal ultrasound findings in our hospital between January and December of 2018.The ultrasound yield of fetal malformations were recorded and compared with the results of induced labor or postpartum review,so as to analyze the prenatal ultrasonographic features and misdiagnosis of fetal malformation.Results:Of the 15863 fetuses examined for antenatal structure,421 were confirmed as malformations by induced labor or postpartum review,including 61 cases of fetal diaphragmatic hernia,14 of callosal dysplasia,45 of digestive tract obstruction,104 of pulmonary cystadenoma,48 of pulmonary sequestration,69 of polycystic renal dysplasia,and 80 of hydronephrosis,accounting for an incidence of malformations being 2.65%.Of these,the yield of prenatal ultrasound detection was 94.06%,indicating the missed diagnosis rate being 5.94%.There was no significant difference between prenatal ultrasound diagnosis and/postpartum review(P>0.05).The main reasons for missed diagnosis were minor morphological changes,obviously early gestational weeks and fetal motions.Conclusion:Most cases of fetal malformation show unique characteristics on ultrasonography.Prenatal ultrasound detection offers high diagnostic value for fetal malformation particularly with significant morphological changes.The diagnostic yield can be increased with serial ultrasonography performed during different gestational periods in pregnant women.
