摘　　要：用CT对闭合性颅脑损伤病人进行颅内压(ICP)估价。方法:对100例颅脑损伤后患者行CT扫描,分析其CT变化特征,对ICP进行估价,并与ICP监护值对照。CT变化特征估价内容:脑室、脑池大小形态、中线结构移位、颅内占位性损伤病灶大小。结果:下列CT改变可估价ICP。1.实质内血肿破入脑室,继发性梗阻性脑积水ICP显著升高。2.第三脑室、基底池受压或消失ICP明显升高。3.侧脑室受压ICP可升高。4.中线结构移位大干5mm时ICP升高。5.占位性损伤灶体积大于20ml时ICP升高程度无明显关系。体积大于20ml时与ICP升高程度相关。结论:通过CT变化,能够估价颅内压,并以此指导治疗,判断愈后。This article aims at estimating the intracranial pressure (ICP) in closed head trauma by CT. Method:Analysing the CT changing features and estimating the intracranial pressure as well as bringing out a contrast between the ICP supervising data and the estimation of CT changing features, such as:the size and shape of the ventricle and cerebral cistern,midline shift,and the size of intracranial mass lesion based on 100 cases with craniocerebral trauma by CT scanning. Results; The following CT changes can be estimated ICP: 1. The parenchymal mass lesion broken in ventricle may be resulted in a-cute hydrocephalus which would cause an apparent rise in ICP. 2. Either compression or obliteration of the third ventricle and the basic cistern, which would cause an apparent rise in ICP too. 3. The midline shift which is more than 5mm,the ICP will appear a rise. 4. It is meaningless in statistics if the size of the mass is less than 20ml,on the contrary,if it is more than 20ml,the ICP will surely appear a rise. Conclusion:intracranial pressure can be estimated by CT changes,and on the basis of this,both treatment direction and prognostic judgement can be timely performed.
