| 目的 评估孕中期超声检查对13-三体综合征胎儿的诊断价值。方法 回顾分析本院26胎经染色体核型分析确诊为13-三体综合征胎儿的声像图资料。结果 前脑无裂畸形12胎(12/26,46.15%)、唇/腭裂9胎(9/26,34.62%)、室间隔缺损9胎(9/26,34.62%)、肾脏异常8胎(8/26,30.77%)、眼眶异常7胎(7/26,26.93%)、鼻发育异常5胎(5/26,19.23%)、脑室增宽4胎(4/26,15.38%)、羊水过多伴宫内生长受限2胎(2/26,7.69%)、独眼1胎(1/26,3.85%)。声像图异常率为92.31%(24/26),均表现为2种及以上异常指标。结论 孕中期超声检查对诊断13-三体综合征具有一定的意义;结合染色体核型分析可提高13-三体综合征的产前诊断率,并能降低其出生率。 |

| Objective To evaluate the value of ultrasonography in diagnosis of trisomy 13 syndrome in the second trimester. Methods Prenatal ultrasonography characteristics of 26 fetuses with trisomy 13 syndrome confirmed by karyotype were retrospectively analyzed. Results Abnormal ultrasonographies symptoms were holoprosencephaly (12/26, 46.15%), lip or cleft palate (9/26, 34.62%), ventricular septal defect (9/26, 34.62%), renal abnormalities (8/26, 30.77%), orbital anomalies (7/26, 26.93%), nose abnormality (5/26, 19.23%), ventriculomegaly (4/26, 15.38%), polyhydramnios and intrauterine growth retardation (2/26, 7.69%), and one eye (1/26, 3.85%). Abnormal ultrasonographies rate was 92.31% (24/26), there was two or more indicators anomalies. Conclusion Ultrasonography is effective in detection of fetuses with trisomy 13 syndrome in the second trimester. Combining with karyotype, it is valuable in improving the prenatal diagnosis of fetus with trisomy 13 syndrome and decreasing the birth rate of fetus with trisomy 13 syndrome. |
