Abstract
Many mechanisms have been postulated to account for vasospasm following subarachnoid hemorrhage (SAH). These include nitric oxide, oxygen-derived free radicals, endothelins, protein kinase C activation, changes in endothelial Ca2 + and K+ fluxes, increases in platelet-activating factor, and loss of smooth muscle phosphatases. Many of these different pathologic systems can be tied together. The excitatory amino acid systems can result in generation of free radicals. The systems that produce reperfusion injury can develop free radicals. Nitric oxide itself can function as a free radical and can increase the production of others. Lipid peroxidation can result in more extracellular glutamate release.
