对新生儿缺血缺氧性脑病CT分度标准的一些补充

The Supplement to Diagnostic Standards of Grade in Neonatal Hypoxic Ischemiaenc Encephalopathy

目的 :通过对 142例新生儿缺血缺氧性脑病随访复查CT图象的变化 ,探讨其CT分度标准与临床分级 ,不同预后不能完全平行的关系 ,提出补充观点以供参考。方法 :将 142例病例图象资料按CT分度标准 ,临床分级标准 ,不同预后重新归纳 ,分析病程演变及预后及CT分度之间的差异特征。结果 :发现预后相关因素当中 ,缺血缺氧发生的脑叶部位及病变区CT值高低应当引起重视和重新认识。结论 :缺血缺氧性脑病在不同脑叶的发生及其缺血缺氧区CT值的高低与预后有一定相关 。

Objective: To analyze CT image data of 142 cases of neonatal hypoxic ischemia encephalopathy(HIE) and explore the cause that the standard of grade on CT is not corresponded correctly to clinical stage.Methods:142 cases of HIE were classified retrospectively according to their different CT grade, clinical stage, and prognosis. Analyses of distinct characteristic of CT grade, clinical course, and prognosis were made. Results: The critical degree of HIE was still corresponded to the location and CT value of the lesion. Conclusion: There is a close correlation between CT value and the location of the lesion as well as the prognosis of HIE.
