EDEMA CEREBRAL CITOTOXICO Y VASOGENICO PDF

Cerebral edema is excess accumulation of fluid (edema) in the intracellular or extracellular spaces of the brain. Contents. 1 Signs and symptoms; 2 Causes. El edema cerebral subyacente en esta patología puede ser de varios tipos: citotóxico, vasogénico, intersticial o hidrostático. El aumento de la presión. Aumento patológico de la cantidad de agua en el cerebro con incremento del volumen del parénquima cerebral. Vasogénico Citotóxico.

This causes a rapid uptake of water and subsequent swelling of the cells. This results in trans-ependymal flow of CSF, causing CSF to penetrate the brain and spread to the extracellular spaces and the white matter. In cytotoxic edema, the blood—brain barrier remains intact but a disruption in cellular metabolism impairs functioning of the sodium and potassium pump in the glial cell membrane, leading to cellular retention of sodium and water. This creates an abnormal pressure gradient and movement of water into the brain, which can cause progressive cerebral edema, resulting in a spectrum of signs and symptoms from headache and ataxia to seizures and coma.

Vasogenic cerebral edema Vasogenic edema Vasogenic brain oedema Vasogenic brain edema. In true isolated cytotoxic edema little change is evident on CT as a mere redistribution of water from extracellular to intracellular compartments does not result in attenuation changes.

This, in turn, results in cellular swelling and a reduction in the extracellular volume which are the primary reasons for increased restricted diffusion on MRI. Cerebral edema is excess accumulation of fluid edema in the intracellular edrma extracellular spaces of the brain.

Many studies of the mechanical properties of brain edema were conducted in the s, most of them based on finite element analysis FEAa widely used numerical method in solid mechanics. Four types of cerebral edema have been identified: Loading Stack – 0 images remaining.

Fast travel to high altitude without proper acclimatization can cause high-altitude cerebral edema HACE. Cytotoxic edema is seen with various toxins, including dinitrophenoltriethyltin, hexachloropheneand isoniazid. If brain herniation occurs, respiratory symptoms or respiratory arrest can also occur due to compression of the respiratory centres in the pons and medulla oblongata.

This type of edema may result from trauma, tumors, focal inflammation, late stages of cerebral ischemia and hypertensive encephalopathy. The one sequence which is able to identify cytotoxic edema, and was thus responsible for a revolution in the imaging of acute ischemic stroke, is diffusion weighted imaging DWI.

It is generally accepted that cytotoxic edema is dominant immediately following an injury or infarct, but gives way to a vasogenic edema that can persist for several days or longer.
