FIG 1. Case 6.
A and B, Anteroposterior (A) and lateral (B) views of the left vertebral arteriogram before stent placement reveal a tubular (9.3 mm in length) and moderately eccentric stenosis (62%) (arrow) of the BA and a tubular (8.3 mm in length) and moderately eccentric stenosis (77%) (arrowhead) of the left IVA. Scale (B): 10 mm.
C and D, Anteroposterior radiographs show the 3.0-mm gfx stent during deployment in the BA (C) and the 3.5-mm Ranger balloon further expanding the gfx stent in the left IVA (D).

FIG 2. Case 6.
A and B, Anteroposterior (A) and lateral (B) views of the left vertebral arteriogram immediately after CAS show sufficient and smooth dilatation of both lesions.
C and D, Anteroposterior (C) and lateral (D) views of the left vertebral arteriogram 3 months after CAS show no restenosis of either lesion.

FIG 3. Case 7.
A, Lateral view of the right carotid arteriogram before stent placement reveals a tubular (11.4 mm in length) and eccentric stenosis (82%) (arrow) of the distal ICA. Scale: 10 mm.
B, Lateral radiograph shows a 4.0-mm NC VIVA balloon catheter further expanding the 3.5-mm Multilink stent in the right distal ICA (arrow).
C, Lateral view of the right carotid arteriogram immediately after stent placement shows sufficient and smooth dilatation of the lesion.
D, Lateral view of the right carotid arteriogram 3 months after stent placement shows no restenosis.

FIG 4. Changes in the percentage of diameter stenosis on the angiograms obtained before (pre-CAS) and immediately after (post-CAS) treatment and at the 3-month follow-up. There is significant reduction of the stenosis rate between the pre-CAS and immediate post-CAS angiograms (P < .0001, paired Student's t-test)
