A, Lateral view of the right vertebral arteriogram before stenting reveals a high-grade eccentric stenosis (arrow) with 93% stenosis and 4.5-mm length. Scale bar: 10 mm.

B, Anteroposterior view of the right vertebral arteriogram before stenting.

C, Illustration shows the gfx stainless steel stent, which was implanted in the intracranial vertebral artery. This stent measures 12 mm in length and can be expanded to up to 4 mm in diameter.
