Serial computed tomographic scans in 39 closed head injury patients were measured by planimetry. The ventricle-brain ratio was computed, and the lateral ventricles were considered to be enlarged or normal based on measurements from a control group. Delayed ventricular enlargement was common after head injury producing low Glasgow Coma Scale scores and prolonged coma, whereas subarachnoid/intraventricular haemorrhage was more common with early enlargement. The degree of ventriculomegaly was related to neuropsychological test performance only when enlargement was delayed. It is postulated that diffuse axonal injury and hypoxic-ischaemic insult contributed to late ventricular enlargement, whereas a compensated obstruction of cerebrospinal fluid may be the predominant cause in the early group.
对39例闭合性颅脑损伤患者的系列计算机断层扫描进行了平面测量。计算脑室-脑比率，并根据对照组的测量结果判断侧脑室是否扩大。颅脑损伤后出现低格拉斯哥昏迷量表评分和长时间昏迷时，延迟性脑室扩大很常见，而蛛网膜下腔/脑室内出血在早期脑室扩大时更为常见。仅当脑室扩大为延迟性时，脑室扩大程度才与神经心理学测试表现相关。据推测，弥漫性轴索损伤和缺氧缺血性损伤导致晚期脑室扩大，而脑脊液的代偿性梗阻可能是早期组的主要原因。
