脑弥漫性轴索损伤的特点及临床诊断

目的　探讨脑弥漫性轴索损伤 (DAI)的特点及临床诊断标准。　　方法　对 58例DAI患者行头颅CT检查 ,其中 3 9例同时行MRI,并分析其临床特点。　　结果　 75 9?I由交通事故致伤 ;患者伤后立即并持续昏迷 ;70 7%的病人无明显颅压增高 ;CT检查 63 8%有异常发现 ,MRI的诊断价值比CT高 ;DAI病变 89 7%在脑的深部及中轴结构 ;该病预后差 ,病死率为 53 5%。　　结论　根据临床特点、CT和MRI检查结果提出DAI的临床诊断标准

Clinical features and diagnosis of diffuse axonal injury in head trauma.

Objective To approach clinical features and diagnosis standard of diffuse axonal injury(DAI) Methods Fifty eight patients with DAI were examined by CT, 39 cases were also received by MRI at same time DAI clinical features were analysed Results 75 9% DAI was caused by traffic accidents, The patients fell in persistent coma immediately after the head injury There was no markly intracranial hypertension in patients of 70 7% DAI, CT scanning showed unusual manifestation in 63 8% DAI MRI value was higher than CT scanning for DAI diagnosis, 89 7% DAI focuses were located in the depths of brain and middle axial structure The prognosis of DAI was not well The mortality rate was 53 5%. Conclusions It was suggested that DAI clinical diagnosis standard may be formed based on clinical features, the manifestation of CT scanning and MRI.
