Subarachnoid hemorrhage and cerebral vasospasm – Literature review
Subarachnoid hemorrhage represents a serious disease with high mortality and morbidity. Two important areas are becoming the central research interest of subarachnoid hemorrhage: cerebral vasospasm and early brain injury. The authors have reviewed the major contributions in experimental subarachnoid hemorrhage documented in the medical literature in the past 5 years. Treatments interfering with...
متن کاملA Review of Hemoglobin and the Pathogenesis of Cerebral Vasospasm
We believe that current experimental and clinical evidence can be most satisfactorily interpreted by assuming that oxyhemoglobin is the cause of cerebral vasospasm that follows subarachnoid hemorrhage. We review the pathogenetic mechanisms by which oxyhemoglobin affects cerebral arteries. The relative importance of each of these mechanisms in the genesis of vasospasm, the biochemical pathways o...
متن کاملCerebral 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 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...
