Endovascular Approaches to Vertebral Artery Stenosis
Summary
Vertebral artery stenosis, most often due to atherosclerotic narrowing at the ostium or along the extracranial segment, represents a significant contributor to posterior circulation ischaemic events. Endovascular management has emerged as a minimally invasive alternative to open surgery, encompassing balloon angioplasty, bare‐metal stenting and drug‐eluting stent deployment. Patient selection hinges on symptomatology, lesion morphology and cerebral perfusion studies, with digital subtraction angiography serving as the diagnostic gold standard and procedural guide. Technical refinements—such as low‐profile balloons, distal protection devices and optimised antiplatelet regimens—have reduced periprocedural risk and enhanced long‐term vessel patency. Current practice balances the need to restore luminal diameter and maintain flow with the avoidance of vessel dissection, embolic complications and in‐stent restenosis. As operators gain experience and devices evolve, these techniques have achieved high technical success rates, translating to improved prevention of recurrent transient ischaemic attacks and strokes in the vertebrobasilar territory.

Endovascular Approaches to Vertebral Artery Stenosis publication trend
The graph below shows the total number of articles in endovascular approaches to vertebral artery stenosis across all publications each year (not limited to Nature Index journals).
Technical terms
Angioplasty: Mechanical widening of a narrowed vessel segment using an inflatable balloon.
Bare‐metal stent: A mesh‐like metal scaffold placed to maintain vessel patency without a drug coating.
Drug‐eluting stent: A stent coated with antiproliferative medication to inhibit neointimal hyperplasia and restenosis.
Ostial stenosis: Narrowing occurring at the origin of the vertebral artery where it branches from the subclavian artery.
Restenosis: Re-narrowing of an artery after an initially successful angioplasty or stent placement.
Digital subtraction angiography (DSA): An imaging technique that visualises blood vessels by subtracting pre-contrast images from post-contrast images to enhance vascular contrast.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
