An example of the procedural steps. (Case 1), a. Curved multiplanar reconstruction of the CTA showed AAA, bilateral CIAA and right EIA occlusion. b. Angiogram showed CTO of the right EIA (dashed line) and right CIAA. c. Lesion was successfully crossed using bidirectional wiring (white arrow head). d. After predilation, a 14-Fr sheath was advanced along the wire (white arrow head). e. Completion angiogram showed residual stenosis at the right EIA despite placement of a self-expanding stent (black arrow head). f. Express LD stent was deployed to support the self-expanding stent (white arrow head). g. Successful dilation of the EIA was achieved. AAA: abdominal aortic aneurysm, CIAA: common iliac artery aneurysm, CTO: chronic total occlusion, EIA: external iliac artery.
