Cerebral Vasospasm
There are essentially two principal end points in cerebrosvascular regulation: maintenance of an adequate supply of blood and energy-yielding substra tes to the brain, despite the imposition of physiological or pathological stresses such as hypoxemia or reduced perfusion pressure, and precise and rapid coupling of regional cerebral bload flow (CBF) to changes in neuronal r equ i r emen t s 3 2 ...
متن کاملVasospasm in Cerebral Inflammation
All forms of cerebral inflammation as found in bacterial meningitis, cerebral malaria, brain injury, and subarachnoid haemorrhage have been associated with vasospasm of cerebral arteries and arterioles. Vasospasm has been associated with permanent neurological deficits and death in subarachnoid haemorrhage and bacterial meningitis. Increased levels of interleukin-1 may be involved in vasospasm ...
متن کاملCerebral arterial vasospasm.
A person in his 20s with known migraine with aura developed infarcts in the right middle cerebral artery and both anterior fields of supply (Figure 1 shows a magnetic tomography diffusion weighted series). Cerebral computed and magnetic tomography with magnetic resonance angiography (MRA) after admission showed normal blood flow and no sign of dissection or vasculitis. Hemicraniectomy became ne...
متن کاملCerebral vasospasm with infarction.
Cerebral Vasospasm With Infarction • A case of intense unilateral cerebral vasospasm with appropriate neurological deficit following rupture of a posterior communicating aneurysm was followed with serial angiography. Associated with the initially intense spasm was subsequent regional hyperperfusion with early venous filling which disappeared as signs of focal cerebral atrophy ensued. These angi...
متن کاملGenetics of Cerebral Vasospasm
Cerebral vasospasm (CV) is a major source of morbidity and mortality in aneurysmal subarachnoid hemorrhage (aSAH). It is thought that an inflammatory cascade initiated by extravasated blood products precipitates CV, disrupting vascular smooth muscle cell function of major cerebral arteries, leading to vasoconstriction. Mechanisms of CV and modes of therapy are an active area of research. Unders...
