严重头外伤后植物状态4例尸检报告

目的:探讨严重头外伤病人植物状态的原因。方法:对4例植物状态死者尸检观察。结果:4例尸检均可见脑及脑干弥漫性水肿,全部病例皮质及半数病例丘脑及豆状核有大灶性梗塞、出血,以及弥漫性轴索损害。结论:脑及脑干弥漫性水肿,广泛性缺血性损害及弥漫性轴索损害是严重头外伤后植物状态的形态学基础,致皮质间及皮质与丘脑间联系中断。

Objective： To probe into the cause of severe head trauma with vegetative state. Methods： To observe 4 autopsy cases with vegetative state. Results： 4 autopsy cases showed diffuse edema within brain and brain stem, All of cases cortex and half of cases thalamus, lenticula showed extensive infarction and hemorrhage as well as diffuse axonal injury. Conclusion： Brain and brain stem with diffuse edema,extensive ischemic damage as well as diffuse axonal injure were the morphologic basis of the head severly posttraumatic vegetative state. These lesions induced the disconnection among cortexes and between cortex mid thalamus.
