【摘要】 目的探讨晚期小脑幕裂孔下疝CT征象与临床预后的关系。方法对临床上出现双瞳孔散大并且诊断为晚期小脑幕裂孔下疝的55例进行回顾性分析。结果55例均有第四脑室闭塞或狭窄。第四脑室按狭窄程度分为闭塞、重度狭窄、轻度狭窄三组进行分析;其中第四脑室闭塞21例,重度狭窄22例,轻度狭窄12例。死亡人数分别为19例(90.48%)、16例(72.73%)、5例(41.67%)。共40例患者死亡(72.73%)。三组病例的病死率统计学比较差异有统计学意义(χ2=6.466,P<0.05)。结论第四脑室狭窄程度与患者病死率有统计学相关性,第四脑室狭窄程度对判断预后具有重要价值。更多还原

【Abstract】 Objective To discuss the CT imaging features of terminal transtentorial hernia and appraisal of clinical prognosis.Methods We had retrospectivly analysed 55 traumatic patients,who had platycoria in clinic and had been diagnosed terminal Transtentorial Hernia.Results Fourth ventricle occlusion or stenosis were seen in all cases.Fourth ventricle changes could be divided into 3 groups(occlusion、serious stenosis、mild stenosis),and were statistical analysed.Of 55 cases,there were fourth ventricle occlusion 21 cases,serious stenosis 22 cases,mild stenosis 12 cases.The deaths in each group were in 19(90.48%),16(72.73%),5(41.67%) respectly,totally 40 patients were dead(72.73%).There was a significant difference in the occurrence of death rate among the above 3 groups(χ~2=6.466,P<0.05).Conclusion In traumatic terminal transtentorial hernia patients,there are significant correlation between the degrees of fourth stenosis and death rate.The degrees of fourth ventricle stenosis is of value in predicting the prognosis.更多还原
