Chiari I型畸形患者小脑扁桃体下疝程度与脊髓空洞症的关系分析

The study of relationship between the degree of cerebellar tonsillar herniation and development of syringomyelia in Chiari I malformation

目的:分析ChiariI型畸形(CMI)患者小脑扁桃体下疝程度与脊髓空洞症的关系。方法:回顾性分析我院1991～2001年142例CMI患者MR检查资料,其中伴发脊髓空洞症67例,无空洞症75例,测量小脑扁桃体下疝值,并对两组结果进行分析。结果:两组结果比较表明,小脑扁桃体下疝程度在空洞组与无空洞组间无差异。结论:ChiariI型畸形患者小脑扁桃体下疝程度与脊髓空洞症的发生无关。

Objective: To analyse relationship between the degree of cerebellar tonsillar herniation and development of syringomyelia in Chiari I malformation(CM I). Materials and Methods: The MRI records of 142 CM I patients from 1991 to 2001 were collected retrospectively. Of the 142 patients, 67 were diagnosed as CM I with syringomyelia and 75 without. The relation of development of syringomyelia and the extent of cerebellar tonsillar herniation were analyzed. Result and Conclusion: The degree of cerebellar tonsillar herniation has no relationship with development of syringomyelia.
