Filter by:A highly desired result during carotid endarterectomy (CEA) is the ability to predict and warn the surgeon if the brain is at risk of damage during the period of time that the carotid artery is cross-clamped for surgical repair of the vessel narrowing. A number of approaches for cerebral monitoring have been developed, including EEG, cerebral oximetry, and measurement of arterial to jugular venous concentration differences of oxygen, glucose or lactate. This study will utilize and compare multiple monitoring approaches for detecting when and if the brain is at risk of injury during CEA. As such, this robust approach to monitoring may permit a more prompt intervention to prevent or limit damage should cerebral ischemia occur. In this study we will compare a processed EEG monitor -- the EEGo, which uses nonlinear analysis to a bispectral (BIS) index monitor, and to the FORE-SIGHT cerebral oximeter to assess the ability of each to identify cerebral ischemia should it occur with carotid artery cross-clamping during CEA. These monitors will be correlated with arterial to jugular venous lactate concentration difference, which has recently been shown to be a sensitive indicator of hemispheric ischemia during CEA.
TIERS is a phase II to generate detailed preliminary data on the efficacy of NeuroAid in post-stroke recovery, and to assess the utility of the rehabilitation outcome measure instruments used.
This is a prospective study including acute ischemic stroke patients aged 18 to 90. Multidetector raw CT is performed in acute ischemic stroke patients. Heart, neck vessels and brain arteries are studied during the same acquisition. Results are compared with the standard methods including transesophageal echocardiography (TEE), Doppler ultrasound (DUS) and MR angiography (MRA) of neck vessels. The main criteria is the ability of CT to classify the stroke etiology correctly according to the TOAST classification in comparison with the standard methods.
The study is designed to assess safety of Vorapaxar when added to standard of care (aspirin) in Japanese subjects with cerebral infarction. The study will assess incidence and tolerability of bleeding, major adverse cardiac events, all adverse events, and effect on expression of markers of inflammation.
The spinal cord is a very important part of the central nervous system. fMRI can be applied to observe functional status of the human spinal cord. Under different conditions, the investigators will see different types of fMRI signals within the spinal cord. In resting state, the investigators might see active/inactive signals, too.
The purpose of this study is to determine whether a new cerebral oxygen monitoring device is effective and comparatively similar to the current approved devices.
CHIMES is a double blind, placebo controlled, randomized, multicenter study to test the hypothesis that NeuroAid is superior to placebo in reducing neurological deficit and improving functional outcome in patients with cerebral infarction of an intermediate range of severity.
Patients with stroke or transient ischemic attack (TIA) are at high risk of poor outcome, recurrence of cardiovascular events or vascular death.Until now, no reliable predictive biological marker could be identified in the acute phase of stroke.We hypothese that, in the acute phase of ischemic stroke or TIA, the increase of cardiac ( brain natriuretic peptide, BNP) or renal markers (albuminuria, cystatin C)might predict recurrence of cardiovascular events or vascular death. We want to assess which one of these markers has the best prognosis value , in a prospective study of 300 stroke patients followed during 3 years.
Hyperglycaemia is a frequent finding in acute ischemic stroke and associated with poor outcome. But the modalities of glucose lowering are still debated. This study will test the efficacy and safety of continuous intravenous insulin protocol versus usual subcutaneous insulin in acute ischemic stroke.
This study will recruit 316 ischemic stroke patients taking aspirin. They will be randomly assigned into cilostazol group or placebo group. Every patients will take 200mg of cilostazol a day or placebo for 1 month. The primary outcome variable of this study is rate of biochemical aspirin resistance on the Ultra Rapid Platelet Function Assay-ASA.
