Cytotoxic cerebral edema refers to a type of cerebral edema, most commonly seen in cerebral ischemia, in which extracellular water passes into cells, resulting in their swelling. The term is frequently used in clinical practice to denote the combination of true cytotoxic edema and ionic cerebral edema. As the pathophysiology of these two types of.
Our results indicate that purely experimental models of brain edema (WI, BBBd) without any parallel pathological process can compromise the basic brain homeostatic activity. Cytotoxic brain edema induced by water intoxication and vasogenic brain edema induced by osmotic BBB disruption lead to distinct pattern of ICP elevation during telemetric monitoring in freely.

Chapter 29 – Cytotoxic and Vasogenic Brain Edema Introduction. Cerebral edema is a buildup of fluid in the brain. It occurs after brain ischemia and different types of. Normal Fluid Movement in the Brain. An understanding of brain edema requires knowledge of normal fluid movement in the. .
It can occur in neurons, glial cells, axons (axonal swelling) and myelin sheaths (intramyelinic edema). Cytotoxic edema may be present not only in infarction/ischemia and trauma, but also in status epilepticus, the acute phase of multiple sclerosis, toxic or metabolic leuko-encephalopathy, osmotic myelinolysis, encephalitis, and presumably in the early phase.

Vasogenic cerebral edema refers to a type of cerebral edema in which the blood brain barrier (BBB) is disrupted (cf. cytotoxic cerebral edema, where the blood-brain barrier remains intact). It is an extracellular edema which mainly affects the white matter via leakage of fluid from capillaries.
