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。
Intracranial pressure (ICP) evaluation was performed on patients with closed head injury using CT. Methods: CT scan was performed on 100 patients with craniocerebral injury. The CT features were analyzed. The ICP was evaluated and compared with ICP monitoring. CT changes in the evaluation of the contents of the contents: ventricular, cerebral pool size and shape, midline structure shift, intracranial space-occupying lesion size. Results: The following CT changes estimate ICP. 1. Substantial hematoma ruptured into the ventricle, secondary obstructive hydrocephalus ICP increased significantly. 2. The third ventricle, basilar pressure or ICP disappeared significantly increased. 3. ICP ventricular compression can be increased. 4. When the shift of the median line is larger, the ICP is increased. There was no significant correlation between the ICP level and the lesion size larger than 20ml. Volume greater than 20ml associated with elevated ICP levels. Conclusion: Through the CT changes, can evaluate intracranial pressure, and thus guide the treatment, to determine the prognosis.
