Filter by:Ischemic stroke with high incidence, mortality, disability and recurrence rate, has become the leading threat to the health worldwide. Intracranial atherosclerotic stenosis (ICAS) is commonly associated with ischemic stroke, especially in Chinese residents. Patients with severe ICAS are subject to a very high risk of recurrent stroke events, despite best medical therapy available. Unstable or complex atherosclerotic plaques can lead to plaque ruptures and distal embolisms, thereby increasing the risk of ischemic stroke recurrence. Studies have shown that activation of inflammatory states may play a driving role in the formation and development of atherosclerosis. So far, it remains unclear which are the best treatments for this condition, especially for high-risk patients. Dl-3-n-butylphthalide (NBP) is a Class I novel drug independently developed in China and was officially approved for use in acute ischemic stroke. Preclinical data showed that NBP can act multiple effects of anti-inflammation, antioxidation and anti-apoptosis by suppressing pro-inflammatory factors and upregulating the expression of anti-inflammatory factors. It is still undetermined whether combined therapy with NBP could enhance the curative effect of intracranial atherosclerosis. The primary purpose of this trial is to evaluate the efficacy of butylphthalide in reducing the degree of arterial stenosis and stabilizing plaques in patients with severe symptomatic middle cerebral artery stenosis.
The primary goal of the trial is to investigate whether the lipid lowering strategy using Alirocumab plus statin could cause more changes from baseline in intracranial atherosclerotic plaque and hemodynamic features during 6 months of follow-up, in patients with asymptomatic intracranial artery stenosis.
The purpose of this study is to verify the efficacy and safety of the Intracranial Stent (Tonbridge) in endovascular treatment of symptomatic intracranial atherosclerotic stenosis.
The primary goal of the clinical trial is to test the effect of oral rivaroxaban plus aspirin in patients with recent stroke/ transient ischemic attack (TIA) caused by intracranial artery stenosis. Participants will be divided into 2 groups to receive either oral rivaroxaban plus aspirin or oral clopidogrel plus aspirin. The main question it aims to answer is whether the experimental group (oral rivaroxaban plus aspirin) is superior to the control group ( oral clopidogrel plus aspirin) to lower recurrent stroke/TIA or death in these patients during 1 year of follow-up.
The purpose of this study is to verify the efficacy and safety of the Intracranial Stent (Tonbridge) in endovascular treatment of intracranial atherosclerotic stenosis.
Background: Effectiveness of Percutaneous transluminal angioplasty and stenting (PTAS) on prevention of events of stroke and death in patients with symptomatic intracranial atherosclerosis (ICAS) is controversial. Aim: to determine whether PTAS plus medical treatment (MT) are superior to MT alone in preventing events of stroke and death in patients with symptomatic ICAS. Methods: The investigators will carry out a randomized controlled trial in 3 hospitals in China. A total of 198 patients with ICAS will be randomized into 2 groups: PTAS+MT and MT group. All patients will receive aspirin (100 mg daily) and clopidogrel (75 mg daily) immediately after randomization, and patients in PTAS+MT group will receive surgery within 5 days after randomization. The patients will be followed up for 1 year after randomization and assessed for events of stroke and death at 30 days and 1 year after randomization, the incidence of recurrent ischaemic stroke in the stenting-involved vascular territory at 30 days and 1 year after randomization, incidence of in-stent restenosis at 1 year after randomization,etc.
