The cerebral supply arteries include the carotid, vertebral, subclavian, and intracranial arteries. There are conditions, or indications, under which these vessels are recommended for stenting. The following are the current indications for interventional treatment of different vessels in clinical practice I. Carotid artery stenting: 1. stenosis ≥ 50% and ischemic symptoms or non-disabling stroke in the blood supply area of the stenosed vessel within six months; 2. asymptomatic stenosis ≥ 60%; 3. tandem lesions requiring endovascular treatment; 4. post-radiotherapy stenosis (symptomatic stenosis ≥ 50%, asymptomatic stenosis ≥ 60%) (60%); 5, restenosis after carotid endarterectomy (symptomatic stenosis ≥ 50%, asymptomatic stenosis ≥ 60%) 6, stenosis due to arterial entrapment (symptomatic stenosis ≥ 50%, asymptomatic stenosis ≥ 60%) 7, stenosis due to fibromuscular dysplasia or pseudoaneurysm; 8, stenosis due to arteritis (symptomatic stenosis ≥ 50%, asymptomatic stenosis ≥ 60%) Patients undergoing surgical procedures prior to general anesthesia. (symptomatic stenosis ≥ 50%, asymptomatic stenosis ≥ 60%). For patients with ≥50% stenosis and symptomatic stenosis, the risk of stroke is increasing as the degree of stenosis increases. At the same time, the benefit of stentoplasty treatment increases. The greatest benefit is seen in symptomatic patients with ≥70% stenosis. II. Vertebral artery stenting: 1. contralateral vertebral artery occlusion with ≥50% stenosis of the vertebral artery diameter and previous TIA or non-disabling ischemic stroke of the vertebrobasilar system within six months; 2. symptomatic dominant vertebral artery stenosis (≥50% stenosis); 3. symptomatic bilateral vertebral artery stenosis (≥50% stenosis); 4. symptomatic non-dominant vertebral artery stenosis with that directly with the continuation of the posterior inferior cerebellar artery, and the patient’s symptoms are related to insufficient blood supply to the ipsilateral posterior inferior cerebellar artery supply area (stenosis rate ≥50%); 5. asymptomatic, but the stenotic vessel (stenosis rate ≥50%) is involved in collateral compensatory blood supply. Subclavian artery stenting: 1.Vessel with stenosis rate ≥ 70% or complete occlusion (systolic pressure difference of 20 mmHg or more in bilateral upper limbs); 2.Inadequate supply of vertebrobasilar artery and/or symptoms of ischemia in the affected upper limbs had occurred within six months. IV. Intracranial artery stenting: 1. recurrent episodes of hypovolemic transient ischemic attack, or non-disabling stroke; 2. the site of intracranial artery stenosis corresponds clearly to the patient’s symptoms; 3. the nature of the lesion is atherosclerotic; 4. angiographically confirmed arterial stenosis ≥ 70% and lesions > 15 mm in length should be treated with caution. These indications are derived from today’s medical research, and physicians need to refer to these criteria to select which patients are suitable for stentoplasty treatment. However, they are not set in stone, and the indications are being adjusted as medical research progresses. At the same time, each patient is different and your doctor will need to make a final treatment recommendation based on your specific case, taking into account the above indications.
