摘要
报告了23例脑弥漫性轴索损伤(DAI)病人。根据其临床表现详细分析了CT扫描的特征及诊断条件,讨论了DAI的病理解剖学方面的变化,并提出了有助于DAI与脑挫裂伤的鉴别诊断依据。DAI的治疗主要为非手术疗法。对合并有颅内压增高的DAI病人可进行减压手术。DAI的预后较差,是重型颅脑外伤死亡的主要原因。
This article presented 23 cases of cerebral diffuse axonal injury (DAI) , analyzed their CT scan features and diagnostic evidences according to their clinic magnificences , discussed pathoanatomy changes , provided helpful evidences for distinguishing them from cerebral contusion and laceration. The main therapy of DAI is non-surgical treatment , decom-perssion is needed while complicated with intracranial hypertension. Prognosis of DAI is not quite good ,which is the main cause of death in severe brain injury.
