目的探讨中、重型弥漫性轴索损伤(DAI)与原发性脑干损伤的临床诊断问题。方法回顾性分析中、重型DAI病人22例的临床资料和治疗、预后、临床分型,并与原发性脑损伤的特征进行比较。结果22例DAI伤者中死亡2例,植物生存2例,重残1例,中残4例,轻残7例,良好6例。伴脑干部位原发损伤的患者预后差。结论DAI是常见的弥漫性脑损伤,建议提出单纯性DAI及复杂性DAI的概念,特别是应该将原发性脑干损伤单独诊断。
Objective To investigate the clinical diagnosis of moderate to severe diffuse axonal injury (DAI) and primary brain stem injury. Methods The clinical data, treatment, prognosis and clinical classification of 22 patients with moderate and severe DAI were retrospectively analyzed and compared with those of primary brain injury. Results Two of the 22 DAI wounded died, 2 were plant survival, 1 was severely disabled, 4 were moderate disability, 7 were mild disability and 6 were good. Patients with primary brain stem injury have poor prognosis. Conclusions DAI is a common diffuse brain injury. The concept of simple DAI and complex DAI is suggested. In particular, primary brain stem injury should be diagnosed separately.
