目的:探讨产前超声在胎儿Dandy-Walker综合征中的重要诊断价值。方法:通过对11例胎儿Dandy-Walker综合征的超声声像图的分析。结果:11例胎儿Dandy-Walker综合征中3例为典型的Dandy-Walker综合征,超声声像图表现为两侧小脑半球分开,蚓部缺失,颅后窝池明显增大,第4脑室增大,两者相互连通,5例为变异型,超声表现为颅后窝池增大,且与第4脑室之间可见小管状连通,3例为单纯颅后窝池增大。结论:由于胎儿Dandy-Walker综合征在超声声像图上具有比较特异的超声表现,因而产前超声在Dandy-Walker综合征上具有重要的诊断价值。
Objective: To investigate the important diagnostic value of prenatal ultrasound in fetal Dandy-Walker syndrome. Methods: The sonography of 11 cases of fetus Dandy-Walker’s syndrome was analyzed. Results: Among the 11 cases of Dandy-Walker syndrome, 3 cases were typical Dandy-Walker syndrome. The echocardiography showed that the cerebellar hemispheres were separated on both sides, the vermis was missing, the posterior fossa of the skull was significantly enlarged, Large, the two connected to each other, 5 cases were variant, ultrasound showed increased posterior fossa sac, and the small ventricular tubular communication between the 4 ventricles, 3 cases of simple posterior fossa enlargement. CONCLUSIONS: Because fetus Dandy-Walker syndrome has a more specific sonographic appearance on ultrasound sonography, prenatal ultrasound has important diagnostic value in Dandy-Walker syndrome.
