• Hypoxia
  • High altitude cerebral edema (HACE) is a severe and sometimes fatal form of altitude sickness that results from capillary fluid leakage due to the effects of hypoxia on the mitochondria -rich endothelial cells of the blood-brain barrier. (wikipedia.org)
  • infection
  • Culture and sensitivity: no growth Cerebrospinal fluid analysis a. b. c. d. obtained via lumbar, cisternal or ventricular puncture indications: inflammation, infection standard precautions are required maintain strict asepsis Cerebrospinal Fluid (CSF) Definition: A watery cushion that protects the brain and spinal cord from physical impact and bathes the brain in electrolytes and proteins.

  • diffuse
  • According to the unproven SBS hypothesis, shaking causes the brain to impact against the inside of the skull, causing widespread brain damage (Diffuse Axonal Injury) and ripping (shearing) the veins between the brain and skull (bridging veins) resulting in bleeding (Subdural Hematoma) in the 'subdural spaces' in between and behind the eyes (Retinal Hemorrhages).

  • stroke
  • During an ischemic stroke , a lack of oxygen and glucose leads to a breakdown of the sodium-calcium pumps on brain cell membranes, which in turn results in a massive buildup of sodium and calcium intracellularly. (wikipedia.org)
  • While not all patients who have experienced a stroke will develop a severe edema, those who do have a very poor prognosis. (wikipedia.org)
  • Injury
  • USMLE has also focused recent efforts on the often unrecognized health care needs of recently returning servicemen and servicewomen (eg, traumatic brain injury and post-traumatic stress disorder), and the families of deployed servicemen and servicewomen. (docplayer.net)
  • palsy
  • Clinical presentation correlates with the severity of associated supratentorial anomalies, varying from mild truncal ataxia and normal intelligence to cerebral palsy. (blogspot.com)
  • fluid
  • It is thought to result from direct transmission of pressure to cerebral capillaries with transudation of fluid from the capillaries into the extravascular compartment . (wikipedia.org)
  • metabolism
  • Altered metabolism may cause brain cells to retain water , and dilution of the blood plasma may cause excess water to move into brain cells. (wikipedia.org)
  • Mechanisms
  • Brain- none CSF- redistributed into compliant paraspinal CSF space Blood- venous blood forced into internal jugular veins When compensatory mechanisms are exhausted, ICP rises more rapidly Eventually, the compensatory mechanisms are exhausted and a sharp rise in ICP will occur.

  • spaces
  • In vasogenic and interstitial edema, electron microscopy has shown an increase of interstitial spaces in white matter amounting to 1000 nm, versus 60 nm in normal white matter .These enlarged extracellular spaces, with free water, may be the dominant source for the total brain water signal, resulting in increased ADC. (mussenhealth.us)
  • It is reabsorbed through the arachnoid villi into the blood in the cranial venous sinuses, and through the perineural lymph spaces of both the brain and the cord. (scribd.com)
  • white matter
  • These images are more sensitive than conventional MRI to determine the extent of edema in both gray and white matter. (mussenhealth.us)
  • 1993) Discrimination between different types of white matter edema with diffusion-weighted MR imaging. (mussenhealth.us)
  • include
  • Other common supratentorial findings include fused thalami, fornices and cerebral peduncles, absence of the septum pellucidum, dysgenesis of the limbic system, cortical malformations and multiple suture synostoses. (blogspot.com)
  • patient
  • Once the patient is hemodynamically stable and has airway and ventilatory status secured, imaging should proceed urgently to define the nature of the intracranial process (see below). (thecardiologyadvisor.com)
