脑水肿已有人提出种种分类方法。常简单的分为血管源性和细胞毒性二型,但它不能包括脑水肿的全部类型。例如,缺血和创伤所致的复合性脑水肿和脑积水时脑室周围的间质性脑水肿即不能被包括在其中。分析时,重要的是脑水肿在细胸内还是细胞外,在灰质还是白质,有否伴有血脑屏障(BBB)开放,有否伴有组织坏死。 Brain edema has been proposed a variety of classification methods. Often simply divided into vasculogenic and cytotoxic type 2, but it can not include all types of cerebral edema. For example, composite brain edema caused by ischemia and trauma and interstitial cerebral edema around the periventricular space during hydrocephalus can not be included. In the analysis, it is important whether cerebral edema is in the breast or in the extracellular, in the gray matter or the white matter, whether there is an open blood-brain barrier (BBB) ​​and whether there is tissue necrosis.
