Cerebrovascular dynamics of autoregulation and hypoperfusion. An MRI study of CBF and changes in total and microvascular cerebral blood volume during hemorrhagic hypotension.
BACKGROUND AND PURPOSE To determine how cerebral blood flow (CBF), total and microvascular cerebral blood volume (CBV), and blood oxygenation level-dependent (BOLD) contrast change during autoregulation and hypotension using hemodynamic MRI. METHODS Using arterial spin labeling and steady-state susceptibility contrast, we measured CBF and changes in both total and microvascular CBV during hem...
متن کاملCerebrovascular reactivity and dynamic autoregulation in tetraplegia.
Humans with spinal cord injury have impaired cardiovascular function proportional to the level and completeness of the lesion. The effect on cerebrovascular function is unclear, especially for high-level lesions. The purpose of this study was to evaluate the integrity of dynamic cerebral autoregulation (CA) and the cerebrovascular reactivity in chronic tetraplegia (Tetra). After baseline, stead...
متن کاملEffects of glyceryl trinitrate on cerebrovascular autoregulation.
their interest in our article. First, we would like to apologize for mis-attributing the statement to the authors. The correct reference in our article was to 11 not 1 and it is not a direct quotation. We believe our survey provides sufficient evidence to raise concerns over the use of transtracheal ventilation using a high pressure source without control of airway pressure, but a survey lackin...
متن کاملGlobal ischemia in dogs: cerebrovascular CO2 reactivity and autoregulation.
One hypothesis on the pathogenesis of post-ischemic-anoxic encephalopathy is impaired cerebral perfusion or the no-reflow phenomenon. Therapies aimed at preventing the development of this phenomenon are increased cerebral perfusion pressure (CPP) and hyperventilation or hypercapnia. Using a dog model in which we have described the progressive development of post-ischemic (PI) cerebral hypoperfu...
متن کاملLoss of cerebrovascular autoregulation in experimental meningitis in rabbits.
The present study was designed to determine whether cerebrovascular autoregulation is intact in experimental meningitis and to examine the relationship between fluctuations in cerebral blood flow (CBF) and increased intracranial pressure (ICP). Measurements of CBF were determined by the radionuclide microsphere technique in rabbits with experimental Streptococcus pneumoniae meningitis with simu...
