目的探讨胎儿前脑无裂畸形的产前超声诊断价值。方法总结产前超声系统筛查、住院引产,产后病理证实为前脑无裂畸形13例,分析其产前超声表现,按照有无合并眼、鼻、唇或(和)硬腭裂、心脏及其他畸形分组,比较其产前检出率。结果在13例产后证实为前脑无裂畸形病例中,含无叶型5例,半叶型5例及叶型3例,合并眼部异常8例(8/13),合并鼻部异常9例(9/13),合并唇或(和)硬腭裂异常6例(6/13),合并心脏异常11例(11/13),合并其他畸形12例(12/13),误诊2例(2/13)。结论产前超声检查是诊断前脑无裂畸形的重要方法 ,诊断准确率高。
Objective To investigate the value of prenatal ultrasound in diagnosis of fetal anterior segment malformation. Methods Summarize prenatal ultrasound system screening, hospital induction of labor, postpartum pathology confirmed that the anterior segment of the brain without rupture deformity in 13 cases, analysis of their prenatal ultrasound, with or without combined eyes, nose, lip or (and) hard palate, heart and other Deformity grouping, compared with the prenatal detection rate. Results Among the 13 cases with postnatal confirmation of anterior segment malformations, there were 5 cases of non-leaf type, 5 cases of half-leaf type and 3 cases of leaf type. 8 cases (8/13) had ocular abnormalities and nasal abnormalities 9 Six cases (6/13) with abnormal lip and / or palate and palate (11/13), 12 cases (12/13) with abnormal heart and 12 cases with misdiagnosis 2/13). Conclusion Prenatal ultrasound is an important method for the diagnosis of anterior segment malformations. The accuracy of diagnosis is high.
