While pharmacological treatment of ischemic cerebrovascular disease is part of the treatment, neurointerventional medicine provides a new method for the treatment of intracranial and extracranial arterial stenosis – stent placement angioplasty, a less invasive, safe and effective treatment. The treatment items mainly include: 1) stent angioplasty for internal carotid artery stenosis; 2) stent angioplasty for vertebral and basilar artery stenosis; 3) stent angioplasty for middle cerebral artery stenosis; 4) stent angioplasty for subclavian artery stenosis.
