Of the 60 patients who underwent SPECT, MRI, and CT, 13 (22%) exhibited areas of cerebral hypoperfusion
on SPECT, but their MRI and CT scans were read as either normal or nonspecific (table 3).
Acute coagulopathy of trauma: Hypoperfusion
induces systemic anticoagulation and hyperfibrinolysis.
Page kidney was first defined by Page (6) in 1939 when he wrapped a canine kidney with cellophane and observed the ensuing hypertension, which he proposed to be caused by renal ischemia and hypoperfusion
(although others have suggested that the hypertension in this setting may be the result of interstitial nephritis and inflammation due to kidney compression).
It is less well appreciated that myocardial infarction can also be seen on even ungated MDCT as a region of myocardial hypoperfusion
By now, research about the effect of polydatin on the VaD induced by chronic hypoperfusion
Additions and/or changes to clinical management included: (1) ordering other studies (such as a CT or MRI); (2) addressing newly found medical morbidities (unexpected space occupying lesions, unexpected trauma patterns, unexpected toxicity patterns, unexpected signs of mild cognitive impairment or dementia, unexpected seizure activity, unexpected potential vascular problems); and (3) discovering other target for treatments beyond those defined by the presence of an Axis I, Axis II, Axis III diagnosis, such as hyperfrontality, hypofrontality, cerebellar hypoperfusion
, limbic system hyperperfusion, temporal lobe abnormalities and others that were found through the use of SPECT scanning and had not been found or even suspected by the state-of the-art diagnostic evaluation described above.
Septic shock was defined as sepsis-induced hypotension, persisting despite adequate fluid resuscitation, with the presence of hypoperfusion
abnormalities or organ dysfunction.
To our knowledge, this case documents for the first time in a parrot a clear relationship between atherosclerosis, peripheral arterial disease, and clinical signs of limb hypoperfusion
Patients with anterior circulation ischemic stroke presenting within 12 h of onset, ineligible for intravenous thrombolysis, an NIHSS score of >4, a mean transit time lesion larger than diffusion--weighted image and an evidence of cortical hypoperfusion
on MRI were included into the trial.
3) An immune-mediated cascade involving T-lymphocytes, various cytokines and endothelial adhesion molecules causing endothelial dysfunction and triggering cerebral vasoconstriction and hypoperfusion
, may explain the absence of a raised BP in some cases of PRES.
The pathogenesis of this condition is unclear, however, a number of factors contribute; microangiopathy, hypoperfusion
and diminished host resistance due to diabetes.
Using knowledge derived from their real-world experiences, instructors teach students about hypothermia effects associated with hypoperfusion
, or shock, and they stress the use of tourniquets and improvised tourniquets via a graded practical exercise.
Chronic brain hypoperfusion
decreased NOS activity, NO synthesis and impaired memory formation in rats (50).
Furthermore, without the dead donor rule, circulatory arrest and the resultant hypoperfusion
of organs would never be required prior to donation, so the number of organs per donor would be similar to donation by brain-dead patients--approximately three per donor.
The type of cognitive deficit seen among people with HF differs in its pathology due to chronic cerebral hypoperfusion
related to impaired cardiac function (Acanfora et al.
