摘　　要：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。Purpose:To explore the probability in diagnosis of diffuse traumatic encephaledema by simple CT measurement.Methods:CT data of 109 cases of adult patients with craniocerebral trauma and 129 cases of normal adult persons were collected.The ventricles at the layers of the third ventricle and the front angle of lateral ventricle were respectively measured and analysed statstcally.The changes of cisterna in abnormal group were observed simultaneously.Results:The width of the third ventricle in normal adults was 2.5 mm to 6.0 mm.In 109 cases of traumatic group narrowing of the third ventricle was 102 cases and narrowing of the laterial ventricle was 95 cases.Conclusion:Encephaledema exists in most brain trauma patients.Narrowing of the third ventricle(male:<2.8 mm,female:<2.5 mm) is an important CT sign in diagnosis of adult diffuse traumatic encephaledema.
