A less mon type of VA disease involves multiple tandem lesions with tortuosity and angulation. The stiff Palmaz stent is illequipped for this. ? Finally, for lesions in the V2 segment, where the vessel passes through the VA canal, the ordinary vessel overstretch mechanism of PTA is inefficient because of the bone surrounding the vessel. Here, we first used flexible balloonexpandable stents (that is, Multilink, GFX), but quickly switched to the selfexpandable type (Radius or Magic Wallstent) because of the theoretical risk of stent pression by the surrounding bone during neck movements.
