摘要
目的:探讨产前超声检查对胎儿前脑无裂畸形(Holoprosencephaly,HPE)诊断的价值。方法:对我院产前超声检查中发现的34例胎儿前脑无裂畸形超声声像图特征及产后结果进行回顾性分析。结果:34例前脑无裂畸形胎儿中无叶HPE 21例,产前超声表现为单一脑室,丘脑融合,脑中线结构消失;半叶HPE 5例,产前超声表现为单一脑室,丘脑部分融合,可见部分脑中线;叶状HPE 8例,产前超声表现为无透明隔腔,侧脑室前角融合。34例前脑无裂畸形胎儿中合并单发或多发畸形29例,其中颜面部畸形23例,心脏畸形8例,肾脏异常4例,脊柱裂1例,肢体异常6例,全身水肿3例,单脐动脉6例,脐带囊肿1例,胃泡显示不清2例,羊水过多5例,羊水过少2例。34例中10例行染色体核型分析检查,结果 3例13-三体,1例18-三体,1例染色体部分缺失,5例染色体核型正常。结论:产前超声检查对胎儿前脑无裂畸形具有较高的诊断价值,降低严重缺陷儿出生率,对临床诊断有重要意义。
Objective: To investigate the clinical significance of antepartum ultrasound in holoprosencephaly(HPE) diagnosis. Methods: A total of 34 fetuses diagnosed as HPE from 2007 to 2013 in our hospital. Sonographic features and postpartum results were analysed retrospectively. Results: Among the 34 fetuses, 21 cases were diagnosed as alobar HPE, 5 cases as semilobar HPE, and 8 as lobar HPE. The characteristic ultrasound findings in alobar HPE were related to the single primitive ventricle, fused thalami, and absence of midline structures; semilobar HPE were related to the single primitive ventricle, partial fused thalami and partia1 absence of midline structures; and lobar HPE were related to the absence of septum pellucidum cavity, and fused anterior horn of lateral ventricle. There were 23 cases combined with other craniofacial malformations, 8 with cardiovascular malformations, 4 with kidney malformations, 1 with spina bifida, 6 with limbs abnormality, 3 with subcutaneous edema, 6 with single umbilical artery, 1 with umbilical cord cyst, 2 with absence of stomach, 5 with polyhydramnios and 2 with oligohydramnios. Ten karyotype analysis resulted in 3 Trisomy 13, 1 Triploid and 5 normal. Conclusions: Prenata1 ultrasound is a useful tool in diagnosing HPE with highly accuracy. It is necessary to undergo antepartum ultrasound for the pregnant women. The antepartum ultrasound is an effective method to screen HPE.
