目的 分析弥漫性脑肿胀 (DBS)的机理并探讨其诊断和治疗。方法 按Zimmerman的CT诊断标准对急诊 46例弥漫性脑肿胀 (DBS)患者临床资料进行研究 ,并对其诊断和鉴别诊断、治疗和预后进行分析。结果 DBS多发生于交通肇事 ,后即刻意识障碍 ,呈持续性昏迷 ,CT表现双侧大脑弥漫性肿胀 ,中线附近散在点状高密度灶。结论 DBS损伤机制与病理诊断的弥漫性轴索损伤 (DAI)是一致的 ,其致死、致残率高。
Objective To analyze the mechanism of diffuse brain swelling (DBS) and to explore its diagnosis and treatment. Methods The clinical data of 46 patients with diffuse brain swelling (DBS) in emergency department were studied according to Zimmerman ’s CT diagnostic criteria, and the diagnosis, differential diagnosis, treatment and prognosis were analyzed. Results DBS occurred in the traffic accident, immediately after the disturbance of consciousness, was persistent coma, diffuse swelling of the bilateral cerebral manifestations of CT, scattered near the midline of dense high-density lesions. Conclusion The DBS injury mechanism is consistent with the pathological diagnosis of diffuse axonal injury (DAI), which leads to high mortality and morbidity.
