Objectives
Narrative objectives1
This study is aimed to clarify the following issues:
1) pathophysiological mechanism of the onset of TIA/ischemic stroke in patients with mild (<50%) carotid stenosis.
2) the incidence of the patients refractory to the best medical treatment due to mild (<50%) carotid stenosis.
3) clinical and radiological characteristics of the patients refractory to the best medical treatment due to mild (<50%) carotid stenosis.
4) the benefits of carotid endarterectomy for the patients refractory to the best medical treatment due to mild (<50%) carotid stenosis.

Assessment
Primary outcomes
the incidence of recurrent ipsilateral ischemic stroke and the duration until recurrent ipsilateral ischemic stroke
Key secondary outcomes
1) the duration until all recurrent ischemic stroke
2) the duration until ipsilateral and all recurrent TIA
3) the duration until ipsilateral and all recurrent amaurosis fugax
4) the duration until ipsilateral and all retinal artery occlusion
5) the duration until all stroke
6) the duration until all death
7) the incidence of de novo silent cerebral infarct within one and two years
8) the incidence of the progression of carotid artery stenosis within one and two years
