Summary
Transradial vertebral artery stenting offers a viable alternative for patients with severe supra-aortic ectasia. This minimally invasive technique provides effective treatment when traditional femoral access is challenging.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurology
Background:
- Severe supra-aortic ectasia can impede access to the vertebral artery origin, complicating endovascular procedures.
- Traditional femoral access may be unsuitable for stenting the vertebral artery in cases of significant ectasia.
Observation:
- A transradial approach was utilized for vertebral artery stenting in two patients.
- The procedure involved radial artery access, local anesthesia, and infusion of a spasm-alleviating cocktail.
- A microguidewire and balloon-expandable stent were used to treat the vertebral artery lesion.
Findings:
- Postprocedure angiography demonstrated improved flow within the vertebrobasilar system.
- No complications related to the radial artery access were observed.
- Patients experienced immediate ambulation and tolerated the procedure well.
Implications:
- Transradial vertebral artery stenting is a promising alternative for complex cases.
- This technique expands endovascular treatment options for vertebral artery stenosis.
- Consideration of the transradial route may improve outcomes in challenging anatomies.
