Prospective, randomized, multi-center clinical trial.
Baseline angiography or MR angiography, CT and CT-perfusion and repeat at 6 months. NIHSS at 12 months. Participants will be randomized into the medical treatment group, or combined treatment group (medical therapy plus stent-assisted angioplasty) in the ratio of 1:2. All recruited patients will receive dual anti-platelets (aspirin and clopidogrel) and probucol. Modifiable risk factors will be controlled by life-style adjustment and/or pharmacological therapy according to major international guidelines. Participants in combined treatment group will additionally undergo stent- assisted angioplasty for the offending intracranial stenosis with Apollo stent. All patients will be scheduled clinical visits by the end of 1st, 3rd, 6th, 9th and 12th months.
|Type||Measure||Time Frame||Safety Issue|

|Secondary||Stroke and death unrelated to the target stenosis; acute myocardial infarction within 12 months; follow up cerebral angiography or MR angiography, CT and CT-perfusion at 6 month; NIHSS at 12 month.|
