颅内高压综合征见于许多疾病,如颅脑损伤、颅内肿瘤、颅内感染、脑积水、脑血管疾病、代谢性疾病、颅内寄生虫病以及某些全身性疾病。一旦出现颅内高压,如不及时去除病因,或降低颅内压力,常发生脑疝而死亡。颅腔是一个闭合性空间,四周都是骨壁,几乎没有伸缩的余地。颅腔内被脑组织(占75%)、脑脊液(占12.5%)和血液(占12.5%)所充满。其中脑组织被压缩的可能性很小,仅脑脊液可自由出入椎管,又可与血液循环进行交换。这样,通过血液和脑脊液循环的调节作用使颅内容物的总体积与颅腔相适应,维持正常的压力。当任何一种颅内容发生病理改变时,颅内压力超过正常水平,就产生颅内高压征。
Intracranial hypertension syndrome is found in many diseases such as craniocerebral injury, intracranial tumor, intracranial infection, hydrocephalus, cerebrovascular disease, metabolic disease, intracranial parasitic disease and some systemic diseases. In the event of intracranial hypertension, if not promptly remove the cause, or reduce intracranial pressure, often occur brain herniation and death. The cranial cavity is a closed space, surrounded by bone wall, almost no room for stretching. The cranial cavity is filled with brain tissue (75%), cerebrospinal fluid (12.5%) and blood (12.5%). Brain tissue is less likely to be compressed, only cerebrospinal fluid free access to the spinal canal, but also with the blood circulation exchange. In this way, through the regulation of the blood and cerebrospinal fluid circulation so that the total volume of intracranial content with the cranial cavity to adapt to maintain normal pressure. When any one of the intracranial lesions occur when the intracranial pressure exceeds the normal level, it produces signs of intracranial hypertension.
