Cerebral hyperperfusion syndrome, also known as reperfusion syndrome, is a dysregulated state of cerebral blood flow following the restoration of arterial blood flow to the brain, usually following treatment of carotid artery stenosis. [1]
If the appearances are not typical, other causes for the symptoms and the imaging abnormalities need to considered before PRES can be diagnosed conclusively. [4] In many cases there is evidence of constriction of the blood vessels (if angiography is performed), suggesting a possible overlap with reversible cerebral vasoconstriction syndrome (RCVS).
Postperfusion syndrome, also known as "pumphead", is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery. Symptoms of postperfusion syndrome are subtle and include defects associated with attention, concentration, short-term memory, fine motor function, and speed of mental and motor ...
Following surgery, a rare early complication is cerebral hyperperfusion syndrome, also known as reperfusion syndrome, which is associated with headache and high blood pressure following surgery. Long term complications include restenosis of the endarterectomy bed, although the clinical significance of this is controversial in asymptomatic patients.
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
The therapeutic effect of hypothermia is not confined to metabolism and membrane stability. Hypothermia can also prevent the injuries that occur after circulation returns to the brain, or what is termed reperfusion injuries. In fact, an individual suffering from an ischemic insult continues suffering injuries well after circulation is restored.
(Mayo Clinic defines Guillain-Barré syndrome as a condition that causes the immune system to attack the body’s nerves, causing “weakness, numbness or paralysis.”) Freddie Freeman Gene Wang ...
Blockage of the aqueduct can lead to hydrocephalus, specifically as a common cause of congenital and/or obstructive hydrocephalus. [ 1 ] [ 2 ] The aqueduct of Sylvius is the channel which connects the third ventricle to the fourth ventricle and is the narrowest part of the CSF pathway with a mean cross-sectional area of 0.5 mm 2 in children and ...
