目的：研究急性硬膜下血肿ＣＴ表现与临床预后关系。方法：对３２例急性硬膜下血肿ＣＴ表现中线移位、基底池压闭及脑肿胀分别评分，结合临床病情（ＧＣＳ），研究预后相关性关系。结果：中线移位和基底池压闭明显者，其脑损伤程度严重。中线移位和基底池压闭与脑损伤积度均呈显著负相关（分别ｒ＝－０．７４４７，ｒ＝－０．６９２４，Ｐ＜０．０１），伴有急性弥漫性脑肿胀者，ＧＣＳ均在８分以下，属重型脑损伤。中线移位≥９ｍｍ者，死亡率７０．６％，基底池消失评分≥１２分，死亡率７３．３％，伴有弥漫性脑肿胀，死亡率７３．６％。结论：急性硬膜下血肿中线移位和脑池受压的程度及有否弥漫性脑肿胀对判断脑损伤程度及预后有意义
Objective: To study the relationship between CT appearance and clinical prognosis of acute subdural hematoma. Methods: The CT findings of 32 cases of acute subdural hematoma were evaluated by midline shift, basal cisterna pressor and brain swelling. The prognosis was studied according to the clinical condition (GCS). Results: The central line shift and basal cisterna closures obviously, the degree of brain damage is serious. There was a significant negative correlation between midline shift and basilar pressure and brain volume (r = -0.7447, r = -0.6924, P <0.01, respectively), with diffuse brain swelling, GCS are below 8 points, is a severe brain injury. The median shift ≥9mm, the mortality rate was 70.6%, basilar pool disappearance score ≥ 12 points, the mortality rate was 73.3%, accompanied by diffuse brain swelling, the mortality rate was 73.6%. Conclusion: The degree of central line shift and cisterna compression and diffuse brain swelling in acute subdural hematoma are significant to judge the degree and prognosis of brain injury
