Filter by:The investigators prospectively want to use the Infrascanner in patients with ischemic stroke, patients with brain surgery, patients with brain tumors, patients with intracranial hemorrhage and patients with a normal CT scan of the brain as part of a diagnostic work-up after head trauma or headache to determine to positive and negative predictive value of the Infrascanner in these different settings.
This study is a 12-month, double-blind, randomized, placebo-controlled trial. The purpose of this study is to determine whether ginseng is effective in the prevention of atherosclerosis and subsequent ischemic stroke. High-risk patients with severe atherosclerosis in the major intracranial arteries and extracranial carotid artery were enrolled.
A multicenter, prospective, randomized, double-blind, placebo-controlled, parallel group study in patients with stroke
The current study aims to evaluate the safety of SP-8203, designing in two stages (stage-1, stage-2) to evaluate the safety and efficacy of the combination therapy of SP-8203 and rtPA for the occurrence of cerebral hemorrhage in patients with acute ischemic stroke receiving rtPA standard of care.
Fluoxetine action on cerebral connectivity changes in acute ischemic stroke patients
NOR-SYS II is designed for finding the cause of acute ischemic stroke lesions in Young adults, age 15 to 49 years. Risk factors, arterial wall changes by intima-media thickness and plaques and consequences of stroke are examined by standardized diagnostics.
BACKGROUND: In 30-40% the cause of ischemic stroke remains undetermined. Most likely, this category hides an additional number of strokes caused by artery-to-artery embolisms due to unidentified atherosclerotic disease, or caused by cardioembolism. Both types are associated with a high risk of recurrent ischemic events and multiple cerebral infarctions. Large-artery atherosclerosis of the brain-supplying arteries is the assumed underlying cause in 10 to 15% of ischemic stroke, mostly deriving from the extracranial carotid artery. Carotid intima-media thickness (cIMT) measured by 2-dimensional (2D) B-mode ultrasonography and estimation of the overall atherosclerotic plaque burden aids future risk prediction. Arterial wall changes, artery caliber variations, degree of stenosis, local hemodynamic alterations and certain plaque characteristics are important for the evaluation of plaque vulnerability and vascular risk stratification. Transcranial Doppler monitoring (TCDM) is a non-invasive bedside examination eligible for detection of microemboli in the human cerebral circulation. HYPOTHESIS: Atherosclerotic stenosis and plaque characteristics can be more accurately assessed by the combination of routine 2D ultrasound, contrast enhanced ultrasound (CEUS), and 3-dimensional (3D) ultrasound. TCDM, CEUS and 3D visualization of the carotid plaque improve the differentiation of stroke etiology and quantification of plaque vulnerability, and aid the prediction of future risk for cerebrovascular events in the individual patient. AIMS: Assessment of prevalence and frequency of Microemboli signals (MES) in unselected patients with cerebral ischemia, the influence of antithrombotic drugs on MES, and the relationship between MES and recurrent stroke or Transient ischemic attack (TIA). Categorization of atherosclerotic carotid artery disease by use of routine and advanced neurosonographic techniques combined with anamnestic and clinical data. Development of a visualization solution tailored for 3D visualization of carotid arteries and semi-automatic plaque segmentation.
The purpose of the Stroke AF study is to compare the incidence of atrial fibrillation (AF) through 12 months between continuous cardiac rhythm monitoring with the Reveal LINQ™ Insertable Cardiac Monitor (ICM) (continuous monitoring arm) and standard of care (SoC) medical treatment (control arm) in subjects with a recent ischemic stroke of presumed known origin.
The primary objective of this study is to evaluate whether, in patients with first-ever atherothrombotic or lacunar stroke without any previous history of atrial fibrillation (AF)/atrial flutter (AFL)/atrial tachycardia (AT), the detection of AF/AFL/AT (silent or symptomatic) by using a continuous cardiac rhythm monitoring with implantable loop recorder (ILR) during the first 12 months of observation is higher than the detection by using a standard cardiac monitoring (physical exam, 12-lead electrocardiogram [ECG] at baseline, 3, 6, and 12 months and Holter ECG at 3 months) in the same period of time.
Prospective, single-arm, multicenter, observational registry of the ACE Reperfusion Catheters and the Penumbra System in Europe. Consecutive patients presenting within 6 hours from symptom onset with an acute ischemic stroke (within the internal carotid artery and internal carotid terminus, middle cerebral - M1/M2 segments) due to anterior circulation large vessel occlusion (LVO) will be treated using the ADAPT technique with thrombo-aspiration as first intention and site routine practice.
