FIG 5. Stent implantation.
A, Stent implantation (gold and stainless steel stents) in a canine model. A gold stent (arrow) was placed in the right distal external carotid artery, and a stainless steel stent (arrowhead) was placed in the left proximal external carotid artery. The radiopacity of the gold stent is superior to that of the stainless steel stent.
B, Stent implantation (gold stents) in canine bilateral vertebral arteries. Gold stents (arrows) were placed in a row in the bilateral vertebral arteries.
