Complex iliac lesions

Consider the challenges of treating complex iliac lesions

  • Multicenter and prospective studies demonstrate suboptimal performance of bare metal stent (BMS) in complex iliac disease1-6 
    • In the COBEST Trial, the five-year primary patency of BMS in TASC II C&D lesions was approximately 25%1
  • Perforation / rupture of the iliac arteries and aortic bifurcation is not uncommon and can be life-threatening7,8
    • In the presence of severe calcification, surgery guidelines recommend stent graft placement for treatment of iliac occlusive disease (IOD)9

The GORE® VIABAHN® Endoprosthesis with PROPATEN Bioactive Surface* and the GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis have been proven to address the treatment challenges in complex IOD.

Demonstrated durability

  • Stent grafts have demonstrated superiority over BMS for treating complex iliac lesions5,6
    • Self-expanding stent grafts, at three years, have demonstrated improved patency over BMS when treating TASC D iliac lesions5 
    • Balloon expandable stent grafts, through five years, have demonstrated higher primary patency compared to BMS1

Proven patency

  • The GORE® VIABAHN® Endoprosthesis family has 12-month patency that approaches published surgical bypass 
    • The GORE® VIABAHN® Endoprosthesis has demonstrated 91% 12-month primary patency10
    • The GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis has demonstrated 97% 9-month primary patency11
    • Meta-analysis review of 3733 open bypass patients across 29 studies demonstrated pooled primary patency of 95%8

The breadth of the GORE® VIABAHN® Endoprosthesis self and balloon expandable configurations offers the widest range of lengths and diameters to treat complex iliac disease12,13
