  • A 57-year-old male with severe intermittent claudication (Rutherford Category 3).
  • TASC II B lesion in the right common iliac artery (CIA) and focal iliac calcification.
  • Relevant patient history:
    • Current smoker with hypertension, hyperlipidemia and previous diagnosis of peripheral artery disease in the right limb that was treated with medication.
    • Baseline ankle-brachial index (ABI) = 0.76.

Focal calcification in the right CIA

Focal calcification in the right CIA


  • Started with bilateral access, identified focal lesion in the distal right CIA that was ~80% stenosed.
  • Angiography showed robust multi-vessel distal runoff down to the foot.
  • Predilated with a 5 × 20 mm ABBOTT® ARMADA PTA Balloon, observed presence of calcification nodule that prevented full dilatation of the percutaneous transluminal angioplasty (PTA) balloon.
  • Delivered and deployed an 8 mm × 39 mm GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis (VBX Stent Graft).
  • Slight residual stenosis observed following VBX Stent Graft deployment.
  • Post-dilatation performed using a 7 × 20 mm ABBOTT® ARMADA PTA Balloon inflated to 14 atm (near rated burst pressure).
  • Final angiogram showed complete restoration of patency in the right CIA with good distal outflow.

At discharge, the patient’s ABI was 1.0. At three-year follow-up, ABI was measured at 0.99 and patient was Rutherford 0 with no report of pain/discomfort or problems with mobility.

Complete restoration of patency

Case takeaways:

Calcified lesions present challenges in endovascular treatment of aortoiliac occlusive disease, including an increased risk of rupture. The VBX Stent Graft provides a barrier that mitigates concerns about neointimal hyperplasia and provides high radial strength to restore patency in even the most calcified lesions.1
