重型颅脑外伤急性大脑半球肿胀的临床及病理分析

The Chinical and Pathological Characteristics of Acute Cerebral Hemispheric Swelling in Severe Craniocerebral Injury

目的 分析 33例外伤急性大脑半球肿胀 (ACHS)的临床特点和病理特点。方法 33例ACHS病例进行回顾性临床分析。手术病人进行取材进行了光镜和电镜检查。结果 32例车祸病人有 17例与摩托车事故有关 ,加速减速旋转三种损伤机制常常并存。ACHS病例病理检查 ,可能为严重挫裂伤引起的炎症反映 ,神经元细胞肿胀调亡 ,并有弥漫性轴突、树突损伤。ACHS非手术治疗的效果可能更为好一些。结论 ACHS是一种特殊类型的脑损伤 。

Objective To analyse the chinical and pathological characteristics in 33 acute cerebral hemispheric swelling(ACHS) cases.Method 33 cases who had suffered from ACHC were reviewed clnically.The cases who had operated,his brain tissues were put off and had made lightscope and electric microscope.Result In 32 Vehicle accidents,there were 17 cases relating to motor accident,there were rotation,acceleration and deceleration,together with three kinds of injures mechanism.In ACHS pathologic exam.,it is appear that inflammatory reaction induced by severe brain contusion and laceration,neurocells apoptosis and diffuse axonal and dendrite injury.Nonoperation are better than operation in ACHS.conclusion ACHS in a special typical cerebral injure,its mechanism and therapy needs to study again.
