Intracranial cerebral stenosis, mainly atherosclerotic stenosis of intracranial arteries, is an important cause of stroke. Current treatment of intracranial artery stenosis includes not only medical options such as risk factor control, antiplatelet therapy (aspirin or clopidogrel), but also interventional treatment, i.e. intracranial angioplasty and stent placement. The procedure involves making a small puncture hole in the patient’s femoral artery, delivering a stent through a catheter to the stenosis site of the intracranial artery, and subsequently releasing the stent to open up the artery site that has shown sclerosis and stenosis, promote blood circulation, and improve the symptoms of cerebral ischemia caused by solid vessel stenosis. It has become an effective treatment option for symptomatic intracranial artery stenosis because of its comparative safety, short operation time, ease of use, minimal injury, certain efficacy and high success rate.
