Stent grafts including Viabahn and VBX are available for lower limb arteries. Viabahn is a self-expandable stent graft that is applicable for superficial femoral artery occlusive disease, injured artery, and hemodialysis fistulas. Viabahn has a high flexibility and is suitable for even tortuous vessels. On the other hand, VBX is a balloon-expandable stent graft and used for aorto-iliac occlusive disease. VBX has stronger radial force and enables more accurate place-ment compared to Viabahn. Additionally, VBX can expand the stent beyond its nominal de-ployed diameter using a larger balloon. This article introduces Viabahn and VBX for lower limb arteries, and focuses on characteristics of the devices, basic procedures, technical tips, com-plications, and literature review.
