目的:研究并分析超声诊断在早期发现脑积水及脑发育异常方面的临床价值。方法:对2010年5月~2014年5月来我院孕龄12周~36周的306例孕妇行常规超声检查,对有胎儿脑发育异常高危因素的孕妇行引道超声检查,并将超声结果与孕妇引产结果做比较。结果:超声检查出畸形胎儿102例,其中64例脑发育异常胎儿,脑发育异常类型及数量分别为:脑积水33例,脑积水合并其他畸形8例,脉络丛囊肿6例,无脑儿12例,脑膨出1例,前脑无裂畸形2例,Dandy-Walker综合征1例,Galen静脉瘤1例。超声诊断符合率达98.4%(63/64),误诊1例。结论:超声诊断对早期发现脑积水及脑发育异常具有重要临床价值,早期诊断率高,简单方面、无电离辐射,可作为胎儿先天性神经血管发育异常首选诊断方法。
Objective: To study and analyze the clinical value of ultrasonic diagnosis in the early detection of hydrocephalus and brain dysplasia. Methods: From May 2010 to May 2014, 306 pregnant women with a gestational age of 12 weeks to 36 weeks in our hospital underwent routine ultrasonography. Ultrasonography was performed on pregnant women with high risk of fetal brain development. Ultrasound Results compared with pregnant women induction of labor results. Results: Totally 102 malformation fetuses were detected by ultrasound, of which 64 cases were abnormal brain development. The types and numbers of abnormal brain development were: hydrocephalus in 33 cases, hydrocephalus and other deformities in 8 cases, choroid cyst in 6 cases, 12 cases of children, 1 case of encephalocele, 2 cases of anterior segment malformation, 1 case of Dandy-Walker syndrome and 1 case of Galen’s aneurysm. The coincidence rate of ultrasonic diagnosis was 98.4% (63/64), misdiagnosis in 1 case. Conclusion: Ultrasound has important clinical value in early detection of hydrocephalus and brain dysplasia. It has high early diagnosis rate, simple aspect and no ionizing radiation. It can be used as the first choice of diagnosis of fetal congenital neurovascular dysfunction.
