Endovascular treatment for stenosis of intracranial and skullbase cerebral arteries is promising but still investigational strategy. Recent development of balloon catheters and application of coronary stents to these arteries has enabled revascularization in selected cases. Indication of this treatment should be strictly limited to elderly/poor risk patients contraindicated to surgical treatment, patients with probable severe cerebral infarction by occlusion, patients with crescendo TIA/progressive stroke refractory to best medical treatment. Result of initial experiences, tips and pitfalls, and present status and future perspective of the treatment are presented. Accumulation of more experiences, development of devices, and technical improvement are needed for further refinement of this treatment in the future.
