【摘要】 目的　分析急性硬脑膜下血肿的血肿厚度、中线移位及其差值在判断患者预后中的作用。　方法　回顾性收集并分析 95例急性硬脑膜下血肿患者的临床资料 ,计算血肿厚度、中线移位及其差值 ,用Kaplan Meier、Wilcoxon Mann WhitneyU检验分析它们与预后的关系。　结果　本组患者血肿厚度 5～ 40mm、中线移位 0～ 35mm ,两者差值 - 2 0～ 35mm ;48例 ( 5 1% )死亡 ,47例 ( 49% )存活 ,存活患者中 18例 ( 19% )预后良好。Kaplan Meier分析显示 :血肿厚度在 17 0mm、中线移位在 15 0mm、中线移位超过血肿厚度 2 2mm的患者生存率为 5 0 % ;预后与这些因素之间有显著的相关性。结论　血肿厚度、中线移位及两者差值是判断急性硬脑膜下血肿患者预后的关键因素 ,并可作为指导临床治疗的依据。更多还原

【Abstract】 Objective To estimate outcomes of patients with acute subdural hematomas by analysing the hematoma thickness, midline shift and the differences between them. Methods Ninety-five patients with acute subdural hematoma were retrospectively studied by calculating hematoma thickness,midline shift and their difference with a statistical analysis of Kalpan-Meier,Wilcoxon-Mann-Whitney U test. Results The hematoma thickness ranged from 5.0 to 40.0 mm and midline shift was from 0 to 35.0 mm.Among these patients,51% died and 49%survived after surgery. 18 patients (19%) showed good or satisfactory results.Kalpan-Meier analysis proved that the survival for patients with hematoma thickness approximately equal to l7 mm and a midline shift 15 mm or whose midline shift exceeded hematoma thickness by 2.2 mm,the survival rate was 50%. Glasgow outcome scale scores were correlated significantly with these parameters. Conclusion The hematoma thickness,midline shift and their difference provided a database from which criteria could be derived, that is crucial for prognosis estimation.更多还原
