目的探讨桥脑出血的临床和ＣＴ、ＭＲＩ的改变，出血部位、出血量与预后的关系。方法选择有头部ＣＴ、ＭＲＩ材料的２４例桥脑出血病例，对其出血部位、出血量与预后的关系进行比较分析。结果发现多部位出血，出血量≥５ｍｌ以上症状复杂，死亡１００％；出血部位单一、出血量＜５ｍｌ症状轻，死亡率２５％，两者差异性显著（Ｐ＜０．０５）。结论桥脑出血的部位、出血量是影响预后的主要因素 Objective To investigate the clinical and CT, MRI changes of pontine hemorrhage, the relationship between the bleeding site, the amount of bleeding and the prognosis. Methods Twenty-four cases of pontine hemorrhage with head CT and MRI were selected. The relationship between the bleeding site, the amount of bleeding and the prognosis was analyzed. The results showed that bleeding at multiple sites, bleeding ≥ 5ml or more complex symptoms, death 100%; bleeding a single site, the amount of bleeding <5ml mild symptoms, the mortality rate was 25%, both significantly different (P <0.05). Conclusion The site of pontine hemorrhage and the amount of bleeding are the main factors affecting the prognosis
