四维超声检查在胎儿唇裂诊断中的应用

Application of 4-D ultrasonography in diagnosis of fetal lip-cleft

目的探讨四维超声成像在胎儿唇裂诊断中的应用价值。方法 24例唇裂胎儿分成孕18～28周及29～40周,分别进行二维及四维超声检查后对其诊断率进行比较分析。结果二维超声对两组的唇裂诊断率均为100%,四维超声对两组的诊断率分别为75%和83.3%,统计学分析均无明显差异。24例中唇裂合并腭裂8例,漏诊4例,唇裂合并腭裂诊断率50%。结论四维超声作为一项无创,反复多次检查的技术,既保留了二维超声动态实时观察的优点,又能更形象、直观的显示胎儿唇裂,丰富了产前胎儿唇裂畸形筛查的检查手段,对围产医学优生优育工作开展有重要意义。

Objective： To investigate the value of 4 - dimensional uhrasonographic imaging in the diognosis of fetal lip - cleft. Methods： 24 fetuses of lipcleft separated into 18 -28 week gestational age and 29 -40 week gestational age, examined for 2 -dimensional and 4 - dimensional ultrasonography, analysised each rate of diagnosis. Results ： The rate of diagnosis about 2 groups examined for 2 -dimensional ultrasonography was 100 percent, for 4 -dimensional ultrasonography was 75 percent and 83.3 percent, no difference on statistics. 24 cases of lip - cleft and palate - cleft in 8 cases, 4 cases of missed diagnosis, the rate of diagnosis lip cleft and palate cleft was 50 percent. Conclusions ： The skill of 4 - dimensional ultrasonograpby known as non - wound, repeated check, not Only to retain the 2 - dimensional ultrasound observation of the advantages of dynamic real - time, But also more vivid, visual display of fetal lip - cleft, Enriched prenatal screening examination method lip - cleft, prenatal and postnatal care on perinatal medicine is important to carry out the work.
