Reversible ischemia determined by xenon-enhanced CT after 90 minutes of complete basilar artery occlusion.

چکیده
Intraarterial thrombolytic therapy decreases mortality in the treatment of acute basilar artery occlusion. An acute decrease in cerebral blood flow (CBF) (<12 mL/100 g per minute) has been reported to invariably result in infarction. We report a case of acute basilar artery occlusion, recanalized within 90 minutes, with reversal of CBF of less than 6 mL/100 g per minute. After reperfusion, areas with persistent CBF of 6 mL/100 g per minute resulted in infarctions on subsequent CT studies. Parenchymal viability is possible after 90 minutes of posterior CBF of 6 mL/100 g per minute.

Myocardial Salvage After Ischemia and Reperfusion Using Magnetic Resonance Imaging and Spectroscopy
To test the hypothesis that contrast-enhanced magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) can dilferentiate reversible from irreversible myocardial injury, these modalities were used to study ischemia and reperfusion in a rat model. The presence of ischemia and reperfusion were confirmed with radiolabeled microspheres (n=6). Groups of animals were subjected to eit...
متن کاملResearch Paper: Optimization of Transient Focal Cerebral Ischemia Model by Middle Cerebral Artery Occlusion
Introduction: Cerebral ischemia is one of the most common causes of death in human populations in the industrial communities. The need for animal models is inevitable to study the pathophysiology and treatment of cerebral ischemia in human. The current study aimed at evaluating the strengths and weaknesses of different techniques used to create ischemia in previous studies and optimizing the tr...
متن کاملSymptomatic cavernous sinus aneurysms: management and outcome after carotid occlusion and selective cerebral revascularization.
BACKGROUND AND PURPOSE Therapeutic internal carotid artery (ICA) occlusion for symptomatic intracavernous artery aneurysms can result in ischemic infarction despite normal clinical balloon test occlusion (BTO). We evaluated outcomes in patients with symptomatic cavernous sinus aneurysms in whom clinical BTO was normal, who underwent carotid occlusion with selective bypass surgery guided by phys...
متن کاملEarly diagnosis of basilar artery occlusion using magnetic resonance imaging.
Three patients with a clinical diagnosis of pontine infarction probably due to basilar artery occlusion were studied with magnetic resonance imaging within 24 hours after onset or latest progression of symptoms. The earliest changes on magnetic resonance images were an absence of signal void in the basilar artery suggestive of severe reduction of blood flow or occlusion (flow-void phenomena). T...
متن کاملThe suboccipital carrefour: cervical and vertebral arterial anastomosis.
PURPOSE Our objective was to anatomically define the anastomoses between cervical and carotid arterial distributions (the carrefour) in the rabbit and to assess the contribution of these collaterals to cortical blood flow (CBF) during cerebral ischemia. METHODS Angiography was carried out in six rabbits with basilar artery occlusion using selective contrast injection into the right subclavian...
