Filter by:The primary purpose of this trial is to compare the efficacy of different doses of investigator product and comparator product in patients with acute ischemic stroke in 4.5 Hours after stroke onset, and provide a basis of drug administration for phase Ⅲ clinical trial. The secondary purpose of this trial is to compare the safety of different dose of investigational product and comparator product in patients with acute ischemic stroke in 4.5 hours afterstroke onset .
The purpose of this study is to determine the efficacy and safety of remote ischemic conditioning combined with intravenous thrombolysis in treating acute ischemic stroke.
Urinary kallidinogenase may assist recovery acute ischemic stroke. This study evaluated the impact of urinary kallidinogenase on NIHSS score, modified Rankin scale (mRS) score and fasting glucose levels in patients with AIS combined with diabetes mellitus and impaired fasting glucose.
The primary objective of the study is to demonstrate that SPG (Sphenopalatine Ganglion) stimulation started within 6 hours from stroke onset slows the expansion of the infarct core volume in acute ischemic stroke.
Thoracic endovascular repair (TEVAR) and transcatheter aortic valve implantation (TAVI) are standard of care procedures to treat thoracic aortic aneurysm or severe aortic stenosis, respectively. Both procedures have a high risk of stroke and silent infarction. Gas has been detected in the cerebral vasculature during these procedures and associated with DWI positive lesions on MRI. The hypothesis is that air emboli contribute to stroke and silent infarction. The investigators propose addressing air emboli by flushing the device with carbon dioxide prior to flushing with saline. This is a pilot study comparing standard saline flush alone to carbon dioxide flushing with saline flush.
To analyze the real situation of intravenous thrombolysis in acute ischemic stroke in China
This study is a prospective, open-label, multi-center, registry study, designed to show that rescue stenting is safe and effective for emergency large vessel occlusion (ELVO) patients who have mechanical thrombectomy failure. Participants with ELVO will initially underwent mechanical thrombectomy usig stent retriever, contact aspiration or both. After failure of mechanical thrombectomy, rescue stenting will be performed.
The aim of the study is to show that an ambulatory ECG telemetry monitoring of some patients hospitalized for cerebral infarction increases the frequency of the diagnosis of atrial fibrillation, cause of their stroke, and reinforces the protection against recurrences.
Despite the advances in neurosurgical and -radiological techniques and intensive care, the mortality and morbidity rates in SAH have not changed in recent years. There is still only a limited understanding of the mechanisms of secondary insults causing brain injury after SAH, also called delayed cerebral ischemia (DCI). In this study, the investigators are exploring the use of quantifiable biomarkers from blood and continuous EEG monitoring as tools for the diagnostics of DCI. Additionally, the investigators are looking into other clinical variables (eg. pain, heart function) as factors of DCI.
The management of patients with ischemic stroke or transient ischemic attack is based on the preservation of a brain area by maintaining sufficient intracranial hemodynamics (IH) and with rapid recanalization. The impact of the patient's position (supine or seated position) on the IH in the event of narrowing or occlusion of an artery is poorly assessed but may be of particular importance. Variations in blood flow according to the positioning of the patient's body are measurable using a transcranial Doppler. The main objective is to verify whether intracerebral hemodynamic changes during early verticalization after ischemic stroke or transient ischemic attack are more frequent in patients with carotid stenosis or occlusion compared to those without stenosis or occlusion.
