About this trial
To study the clinical outcomes after implantation of balloon-expandable drug-eluting stents in patients with symptomatic intracranial atherosclerotic stenosis in prevention of composite event of any stroke and death within 30 days and ischemic stroke in the territories of the responsible artery from 31 days to 1-year.
Eligibility criteria
Qualifiers
Age ≥ 18 years.
According to clinical and angiographic evidence, symptomatic intracranial arteries stenosis within 3 months include vertebral artery V4 segment or internal carotid artery C2-C7 segment, and the degree of diseased arterial stenosis is between 70%~99% (WASID method).
Patients have more than 1 episode of symptoms including stroke or transient ischemia attack (TIA) after intensive medical treatment (including antiplatelet therapy, antihypertensive, hypoglycemic and lipid-lowering treatments).
Patients have at least 1 risk factor for intracranial atherosclerosis, including previous or existing hypertension, hyperlipidemia, diabetes mellitus, smoking, alcohol consumption, obesity, underlying heart disease, family history of atherosclerotic vascular disease, hyperhomocysteinemia and so on.
Disqualifiers
Patients who cannot receive dual antiplatelet therapy due to existing diseases or with server coagulation dysfunction, uncontrolled serious infections, serious systemic diseases, uncontrollable hypertension and other conditions are not suitable for surgery.
Patients with aneurysm that cannot be treated in advance or at the same time or are not suitable for surgery.
Gastrointestinal disease with active bleeding.
Myocardial infarction or massive cerebral infarction within 2 weeks.
