Magnetic resonance angiography (MRA) will be used to calculate the number and incidence of restenosis among all participants.
| 1 year after stenting |
| The degree of restenosis of the target vessel | The degree of restenosis will be assessed by performing magnetic resonance angiography (MRA) using the Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) trial method for the measurements of arterial stenosis. | 1 year after stenting |
| Change from baseline in The National Institutes of Health Stroke Scale (NIHSS) score | The National Institutes of Health Stroke Scale (NIHSS) score is a tool used to objectively quantify the impairment caused by a stroke and to evaluate stroke severity. It ranges from 0 to 42, with 42 being the highest and 0 being the lowest. The higher the NIHSS score, the worse the neurological function. | Baseline and 30 days after stenting |
| Change from baseline in modified Rankin Scale (mRS) score | The modified Rankin Scale (mRS) score is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke.it ranges from 0 to 6 .The higher the mRS score, the worse the prognosis. | Baseline and 30 days after stenting |
