Figure

  • Figure 1 (A) CTA showed a total occlusion of the left proximal subclavian artery (arrowheads). (B, C) CTA showed a stent fracture of left subclavian artery (arrowheads). (D) Chest X-ray on the day of PTA showed continuity of left subclavian stent (arrowheads). (E) Chest X-ray 11th day after PTA showed a stent fracture of left subclavian artery at mid portion (arrowheads). (F, G) Chest X-ray on the day of and 6 months after re-PTA showed repaired continuity of left subclavian stent (arrowheads).CTA = computed tomographic angiography; PTA = percutaneous transluminal angioplasty.
