目的:探讨简单的CT测量诊断弥漫性外伤性脑水肿的可能性。方法:收集成人颅脑外伤后CT轴位扫描并有复查的CT资料109例和正常成人CT资料129例,取三脑室和侧脑室前角层面分别测量脑室的大小等,对照两组测量结果,并经统计学处理。病变组同时观察主要脑池的改变。结果:正常成人三脑室宽径为2.5~6.0mm。病变组109例中,三脑室变窄102例,侧脑室变窄者95例。结论:大多数颅脑外伤者有脑水肿。三脑室宽径变窄(男性<2.8mm,女性<2.5mm)可作为诊断成人弥漫性外伤性脑水肿的一个重要指标。
Objective: To explore the possibility of simple CT measurement in diagnosis of diffuse traumatic brain edema. Methods: One hundred and nine cases of CT scan and 129 cases of normal adult CT data after CT scan of adult craniocerebral trauma were collected. The size of ventricles were measured in three antrum and anterior horn of lateral ventricle. And by statistical processing. Lesion group also observed changes in the main cisterns. Results: Normal adult ventricle width of 2.5 ~ 6.0mm. Of the 109 patients with lesions, 102 were narrowed in the third ventricle and 95 were narrowed in the lateral ventricle. Conclusion: Most brain trauma patients have brain edema. Narrowing of the width of the third ventricle (male <2.8 mm, female <2.5 mm) can be used as an important indicator of diagnosis of diffuse traumatic brain edema in adults.
