Filter by:The goal of this clinical trial is to compare the safety and effectiveness of anticoagulation combined with antiplatelet therapy in acute ischemic stroke (AIS) patients with concomitant non-valvular atrial fibrillation (NVAF) and extracranial/intracranial artery stenosis. Participants will be 1:1 randomized into anticoagulation alone or anticoagulation combined with antiplatelet therapy. The primary endpoint is composite events 3 months after enrollment.
The purpose of this study is to explore the safety and efficacy of remote ischemic conditioning in patients with carotid artery stenosis receiving carotid endarterectomy.
RECAS is a prospective cohort of 1,000 patients with carotid artery stenosis (CAS) and undergoing revascularization therapy or standard medication treatment alone. The goal of this study is to validate whether CAS revascularization when compared to standard medication treatment alone, can effectively reduce the progression of Cerebral small vessel disease (CSVD) burden, as well as improve the severity of retinal pathologies and cognitive impairment. Therefore, Patients aged ≥ 40 years have more than 50% stenosis in unilateral carotid artery and sign informed consent will be recruited. In this study, patients will be asked to undergo Computed Tomography Angiography (CTA)/ Digital Subtraction Angiography (DSA), Computed Tomography Perfusion (CTP),multimodal Magnetic Resonance Imaging (MRI), Optical Coherence Tomography Angiography (OCTA) and neuropsychological testing. Estimated follow-up can be up to 10 years.
The Predictive Value of Clinical Data on Perioperative and Postoperative Risk Events in Patients With Head and Neck Artery Stenosis
The purpose of CARE-HBOT study is to evaluate whether patients with symptomatic severe carotid artery stenosis with cognitive impairment who underwent hyperbaric oxygen therapy plus standard medical treatment after stent implantation could improve their cognitive function compared with those who underwent standard postoperative medical treatment.
The goal of this clinical trail is to compare the differences in carotid plaque Treg cells' gene signature for activation, proliferation, and suppressive function using scRNA-seq in patients treated with IL-2 compared to control.
Plastic particles are a ubiquitous pollutant in the living environment and food chain, so far, plenty of studies have reported the internal exposure of microplastics and nanoplastics in human tissues and enclosed body fluids. Neurosurgery is the only department that can open the skull. In addition to blood and cerebrospinal fluid, there are brain tissue and tumors in the presence of lesions. Whether any of these microplastics and nanoplastics are present remains a mystery. This prospective observational study will harvest biological samples of neurosurgery patients. The objective of this research is to be able to detect microplastics and nanoplastics on blood and operation samples of neurosurgery patients.
Carotid endarterectomy (CEA) is a well-established procedure for preventing ischemic brain damage. Stenosis of the precerebral vessels are often combined with arterial hypertension. In recent decades, many works have appeared that indicate that the course of arterial hypertension (AH) changes after CEA. However, it remains unknown how this is related to the choice of surgical tactics.
To test the effects of 6 month additional intervention of ORIENT diet versus usual medical treatment for Intracranial / Carotid Stenosis on cognitive decline, multi-mode MRI image markers and serum and fecal biomarkers in a randomized controlled trial of 120 patients with intracranial / carotid stenosis, who are aged older than 40 years and without dementia.
Carotid artery stenting (CAS) is one of major treatments in prevention of ischemic stroke. Because of sinus reflex due to stenting and balloon dilatation, persistent post-surgery hypotension is a common perioperative event. Persistent hypotension can lead to perioperative adverse events like ischemic stroke, myocardial infraction, renal failure and death; or more usually, it prolongs length of stay and hospital expenses. Renin-angiotensin-aldosterone inhibitor (RASI) could inhibit the release of catecholamine and may lead to higher rate of persistent hypotension after CAS compared to other hypertensives.Thus, the investigators aim to investigate the effect of pre-operation antihypertensive drugs on persistent hypotension after stenting, and followed burden in carotid artery stenting comorbid with hypertension patients.
