脑水肿是指脑组织的含液量增多而引起的脑容量增加。在病理形态学上,脑细胞间隙和血管周围间隙液体增多称为脑水肿,而脑细胞内液体的积蓄则为脑肿胀。此二者可发生于同一疾病过程中的不同阶段,到后期往往同时存在,但在实际临床工作中不能区分,故统称为脑水肿。脑水肿是中枢神经系统受到各种外源性或内源性有害因素的刺激时,所产生的一种最常见的非特异性反应,可见于临床多科系的许多疾
Brain edema refers to increased brain fluid volume caused by increased brain fluid. In histopathology, the increase of fluid in the gap between the brain cells and the perivascular space is called brain edema, while the accumulation of fluid in the brain cells is brain swelling.
