ASSISTII
Study hypothesis
H0: Adjunctive stenting to optimal medical therapy is not superior to optimal medical therapy alone in reducing ipsilateral stroke risk in patients with symptomatic intracranial atherosclerotic stenoses.
H1: Adjunctive stenting to optimal medical therapy is superior to optimal medical therapy alone in reducing ipsilateral stroke risk in patients with symptomatic intracranial atherosclerotic stenoses.

Eligibility
Participant inclusion criteria
1. 18-75 years of age
2. ≥1 major atherosclerotic risk factors (arterial hypertension, hyperlipidemia, diabetes mellitus, hyperhomocystinemia and smoking)
3. Recurrent ischemic events (transient ischemic attack [TIA] and/or stroke) attributed to an intracranial stenosis ≥50% at digital subtraction angiography (DSA)
4. Evidence of perfusion deficit at the territory referable to the target stenosis in computed tomography (CT)-perfusion
5. The diameters of the parent arteries were between 2.0 to 4.0 mm, and length of stenoses <12 mm
6. Modified Rankin score ≤2 prior to last ischemic event

2. Intracranial hemorrhage and major ischemic stroke (National Institutes of Health-Stroke-Scale [NIHSS] ≥8) in the same hemisphere as the target lesion within 6 weeks
3. A potential source of cardiac embolism
4. Concurrent intracranial tumors, cerebral arteriovenous malformation (AVM) and aneurysms
5. Presence of a neurological illness that can confound the diagnosis of TIA or stroke
6. Known contraindication to aspirin, clopidogrel, probucol, heparin, stainless steel, anesthesia, or X-ray contrast
7. Uncorrectable bleeding diathesis; previous stenting of the target artery
8. A positive pregnancy test
