摘要
目的 探讨小脑延髓池径线的超声检查价值及其临床意义。方法 选择2014年3-12月沈阳市妇婴医院产科诊治的孕产妇242例为研究对象,均接受产前超声检查,分析孕周与小脑延髓池宽度的关系。对所有孕妇进行随访,观察小脑延髓池宽度与胎儿预后的关系。结果 32周及之前,小脑延髓池宽度与孕周间呈正相关（r=0.724,P〈0.05）;33周及之后,小脑延髓池宽度与孕周间呈负相关（r=-0.721,P〈0.05）,小脑延髓池宽度〈8.0 mm及8-10 mm的胎儿发生畸形的比例分别为0.58%（1/172）和3.08%（2/65）,均显著低于小脑延髓池宽度〉10 mm的胎儿畸形的比例3/5,差异有统计学意义（P〈0.05）。结论 胎儿小脑延髓池发育与孕周存在密切关系,当小脑延髓池宽度明显增大至〉10 mm,胎儿畸形发生概率明显增加。
Objective To explore the value of ultrasound in cerebellomedullary cisterna diameter detection and its clinical significance. Methods From Mar. 2014 to Dee. 2014, a total of 242 pregnant women from Department of Ultrasound of Shenyang Maternity and Infant Hospital were selected as the research objects, all of which received prenatal ultrasound examination, and the relationship between gestational age and cerebellomedullary cistern width was observed. All pregnant women were followed up to observe the rela-tionship between the width of the cerebellomedullary cisterna and fetal prognosis. Results At 32 weeks and before, there was a positive correlation between the width of the cisterna and gestational age（ r = 0. 724,P 〈 0. 05） ;at 33 weeks and later,the width of the cisterna magna was negatively correlated with gestafional age （ r = - 0. 721, P 〈 0.05 ）, the fetal malformation proportion of cerebellomedullary cisterna width 〈 8.0 mm and 8-10 mm was 0. 58 % （ 1/172 ） and 3.08 % （2/65） respectively, significantly lower than that of the cerebellomedullary cisterna width 〉 10 mm（ 3/5 ）, the difference was statistically significant （ P 〈 0. 05 ）. Conclusion Fetal cisterna development has a close relationship with gestational age, and when the cerebellomeduUary cisterna width increases to 〉 10 mm, the probability of fetal malformation is significantly increased.
