Non-Significant Risk Study Comparing the Nautilus NeuroWaveTM to Transcranial Doppler as an Aid...
Cerebral VasospasmThe purpose of the study is to determine the sensitivity, specificity and predictive values of the Jan Medical NeuroWave System in detecting moderate and severe vasospasm in comparison to Trans Cranial Doppler(TCD).
Safety and Feasibility of Hypertonic Saline Solution After Aneurysmal Subarachnoid Hemorrhage:
Subarachnoid HemorrhageCerebral Vasospasm1 moreSubarachnoid hemorrhage (SAH) occurs after rupture of cerebral aneurysms. Treatment of SAH focuses on avoiding medical complications including cerebral vasospasm, which may result in limited circulation to the brain. Cerebral vasospasm, or thinning of the arteries of the brain, is a feared complication that could potentially cause stroke and worst outcomes after SAH. Hypertonic saline (HTS) is a compound that may be used to prevent vasospasm following SAH by enhancing the circulation in the brain. This study will evaluate if a protocol of volume expansion with HTS is safe and effective in patients with subarachnoid hemorrhage for the prevention of cerebral vasospasm.
Safety of Intravenous Milrinone for the Treatment of Subarachnoid Hemorrhage-induced Vasospasm
Cerebral VasospasmSubarachnoid HemorrhageThe aim of this study is to evaluate the tolerance of intravenous milrinone combined to the current standard treatment for cerebral vasospasm following subarachnoid hemorrhage. Assessment of IV milrinone safety in this setting is mandatory before the conduction of a large study assessing its effectiveness.
Stellate Ganglion Block in Preventing Cerebral Vasospasm Secondary to Subarachnoid Hemorrhage
Subarachnoid HemorrhageAneurysmal1 moreTo investigate whether the stellate ganglion block is helpful in relieving cerebral vasospasm during aneurysmal coil embolism surgery. The effect was assessed by Transcranial Doppler (TCD).
An Evaluation of Non-invasive Acoustic Approach to Detect and Monitor Cerebral Vasospasm
VasospasmIntracranial1 moreHeadSense (HS)-1000 device, a proprietary non-invasive brain monitor, is expected to safely and accurately monitor physiological signs of the brain with minimal discomfort to patients, providing information about normal or abnormal brain-related conditions and providing decision-making support for physicians. The investigators hypothesize that the HS-1000 is capable of detecting vasospasm using the raw acoustic data derived from the noninvasive procedure.
An Evaluation of a Non-invasive Brain Monitor
Brain InjuriesSubarachnoid Hemorrhage4 moreHS-1000 device, a proprietary new non-invasive brain monitor, is expected to safely and accurately monitor physiological signs of the brain with minimal discomfort to patients, providing information about normal or abnormal brain-related conditions and providing decision-making support for physicians. Investigators hypothesis that the HS-1000 is capable of detecting and monitoring various neuropathologies, using the acoustic raw data derived from the noninvasive procedure.
Effect of Intraventricular tPA Following Aneurysmal Subarachnoid Hemorrhage
Subarachnoid HemorrhageCerebral Vasospasm2 moreThis study will evaluate the hypothesis that the administration of intraventricular tPA reduces the rates of cerebral vasospasm and ventriculoperitoneal shunt-dependent hydrocephalus in patients with aneurysmal subarachnoid hemorrhage.
Predictive Value of Mean Flow Velocity by TCD in Early Cerebral Vasospasm in Aneurysmal Subarachnoid...
Subarachnoid HemorrhageAim of this work is to evaluate the transcranial doppler in prediction of cerebral vasospasm in aneurysmal subarachnoid hemorrhage and also to evaluate their advantages over clinical scales in predicting CV.
Role of Proteomics and Metallomics in Cerebral Vasospasm Following Subarachnoid Hemorrhage
Subarachnoid HemorrhageCerebral Vasospasm1 moreThe purpose of this study is to determine the role of Proteomics and Metallomics in Cerebral Vasospasm following Subarachnoid Hemorrhage
Role of CT Perfusion in Predicting Poor Outcome After Subarachnoid Hemorrhage
Subarachnoid HemorrhageCerebral Vasospasm1 moreProspective evaluation of patients with subarachnoid hemorrhage (SAH) will be done by computed tomography angiography (CTA) and perfusion imaging (CTP) for any correlation between degree of vasospasm and perfusion deficit as well as evaluating the ability of CTP to predict delayed cerebral ischemia.
