Intracranial infection is always accompanied with inflammatory angiospasm, ICP & CCP can be predicted accurately according to typical change of TCD parameter. Prediction accuracy of TCD in ICH is better than that in intracranial infection.

• 颅内感染多合并炎性血管痉挛,根据特征性TCD频谱参数改变可较准确预测ICP、CPP,对脑出血的预测准确性好于颅内感染。
