颅内压增高不是一种疾病,而是多种疾病所共有的一种常见的征候群。正常成人颅内压为60～180mmH_2O(相当于4.5～13.5mmHg)。当侧卧时所测得的蛛网膜下腔的压力超过200mmH_2O时称为颅内压增高。颅内压增高如不能及时诊断和解除病因或采取措施缓解颅内压力,易产生脑疝,继则往往由于脑疝而导致死亡。因此对于颅内压增高的诊断、治疗是神经科的重要课题。一、病因与发病机理正常情况下,颅腔内通过血液循环和脑脊液循环的调节,使颅腔内容物适应颅腔容积,维持颅内压的平衡。颅内压的增高,就是颅腔的不变性与颅内容物的有限可变性之间矛盾不能调和的结果。
Increased intracranial pressure is not a disease but a common symptom that is common to many diseases. Normal adult intracranial pressure of 60 ~ 180mmH_2O (equivalent to 4.5 ~ 13.5mmHg). When measured when the lateral subarachnoid pressure exceeds 200mmH_2O when the intracranial pressure is increased. Increased intracranial pressure, such as failure to timely diagnosis and removal of the cause or take measures to alleviate intracranial pressure, prone to hernia, followed by hernia often leads to death. Therefore, for the diagnosis of intracranial hypertension, treatment is an important neurological issue. First, the etiology and pathogenesis Under normal circumstances, the cranial cavity through the blood circulation and cerebrospinal fluid circulation regulation, so that the content of the cranial cavity to adapt to the cranial cavity volume, maintaining the balance of intracranial pressure. Increased intracranial pressure, that is, the invariance of the cranial cavity and the limited variability of intracranial content can not be reconciled the result of conflict.
