Cerebral hyperperfusion syndrome after endovascular stent graft reconstruction for postirradiated carotid blowout syndrome: a case report [PDF]
Background Cerebral hyperperfusion syndrome (CHS) is a failure of autoregulation after a revascularization procedure. It has rarely been reported in patients with no pre-existing cerebral hypoperfusion. Case Report We present a rare case of a patient who

Cerebrovascular reactivity to hypercapnia during sevoflurane or desflurane anesthesia in rats [PDF]
Background Hypercapnia causes dilation of cerebral vessels and increases cerebral blood flow, resulting in increased intracranial pressure. Sevoflurane is reported to preserve cerebrovascular carbon dioxide reactivity.

Quantitative Analysis of Brain CT Perfusion in Healthy Beagle Dogs: A Pilot Study
Brain computed tomography (CT) perfusion is a technique that allows for the fast evaluation of cerebral hemodynamics. However, quantitative studies of brain CT perfusion in veterinary medicine are lacking. The purpose of this study was to investigate the

Melatonin does not attenuate dynamic cardiovascular and cerebrovascular reflex responses to acute hypotension in healthy men [PDF]
BackgroundMelatonin has been shown to attenuate the reflex sympathetic increases that arise in response to orthostatic challenges. We tested the hypothesis that the attenuated sympathetic increase induced by melatonin premedication may weaken the ...

Endothelial dysfunction indicators and hemorheological properties in acute ischemic stroke
We evaluated endothelial dysfunction and hemorheological indicatorsin acute ischemic stroke. The hemorheological indicators(blood viscosity, plasma viscosity, hematocrit, erythrocyte aggregationand deformability, fibrinogen concentration) were ...

Risk of perioperative stroke and cerebral autoregulation monitoring: a systematic review
Background Perioperative stroke, delirium, and cognitive impairment could be related to management and to variations in blood pressure control, cerebral hypoperfusion and raised blood volume.
