Mechanism of cerebral vasospasm following subarachnoid hemorrhage in monkeys.
This paper reviews our recent studies on the mechanism of cerebral vasospasm following subarachnoid hemorrhage (SAH) in monkeys. Middle cerebral artery (MCA) vasospasm was maximal at 7 days, resolving by 14 days, and absent at 28 days after SAH. Arterial fibrosis was not detected during vasospasm, although there was intimal hyperplasia with fibrosis 28 days after SAH. On scanning electron micro...

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 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...
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...
