| 中文摘要: |
| 目的揭示高颅压状态下的脑循环动力学(CVDI) 变化的特点。方法对33 例高颅压患者进行腰穿测
颅压及CVDI 检测,并且根据腰穿实测颅压值把病人分三组,对三组CVDI 检测值进行分析。结果轻度颅压增高
( ICP < 350mmH2O) CVDI 中仅有血管顺应性下降。当颅压高于350mmH2O ,CVDIU 中的血流量,血流速度下降,血
管阻力增高,血管弹性减退。结论CVDI 随颅压改变有明显变化,可用其指导临床诊断及监护。 |

| Objective To reveal the characteristic changes of cerebrovascular hymodynamic indexes (CVDI) in intracranial hypertension. Methods thirty-three hospitalized patients were examined their CVDI and intracranial pressure ( ICP) .
they were divided into three groups according to their ICP ,and then analysed. Results In groups of ICP < 350mmH2O ,
the characteristic CVDI changes were only deterioration in the function of cerebralvascular autoregulation ,but when ICP >
350mmH2O ,CVDI had remarkable changes. Especially showed that the decreases in the total cerebral blood flow and velocity ,and increases in the cerebral vascular resistance ,as well as deterioration in the function of cerebral vascular autoregulation. Conclusion CVDI in patients with intracranial hypertension has definite changes ,we can use it to indicate our diagnosis and monitor. |
