Figures
- Fig 1.
Representative images from patient 2.
A, Stenosis of the right vertebral artery origin visualized in anteroposterior projection with subclavian artery injection.
B, Occlusion of the left vertebral artery origin visualized in anteroposterior projection with subclavian artery injection.
C, Distal protection device deployed in the distal cervical right vertebral artery through the radial access and balloon-expandable stent traversing the lesion over the 0.014-inch microwire of the device.
D, Complete resolution of the right vertebral origin lesion after stent deployment.
- Fig 2.
A schematic representation of the retrieval process. Insets contain photographs of the distal portions of the 2 retrieval catheters.
A, Standard retrieval catheter is limited by sharp angulation and protruding struts of stent in the subclavian artery.
B, Angulated 4F angiographic catheter provides the advantage of navigating through the sharp angulation and protruding struts of stent.
