Percutaneous transluminal angioplasty and stenting (PTAS) in patients with symptomatic intracranial vertebrobasilar artery stenosis (IVBS).

In certain individuals with medically unresolved, severe, symptomatic and non-acute IVBS, elective vertebrobasilar PTAS appears to be both safe and effective. Various stent designs and angioplasty-assisted techniques should be taken into consideration based on the specific clinical and radiological traits of the lesions. Future randomised controlled trials are required to verify these results.
