PTA failures of AV graft lesions
Percutaneous transluminal angioplasty (PTA) has significant limitations when treating Arteriovenous (AV) access lesions1
- Patency rates diminish with each successive angioplasty procedure1,2
- In the REVISE Clinical Study, patients undergoing PTA who had a previous intervention at the target lesion had lower primary patency at 6 months when compared with patients with no prior interventions at the target lesion (29.2% vs. 43.9%)1
- The 2006 KDOQI guidelines acknowledge that alternatives to PTA should be considered when PTA fails twice within three months3

The GORE® VIABAHN® Endoprosthesis with PROPATEN Bioactive Surface* has proven patency independent of the number of prior interventions1
Proven patency
- Provided consistent patency independent of the number of times a lesion has previously been treated1
FEWER REINTERVENTIONS
- Reduced the average number of reinterventions by 27% over two years within the circuit compared to PTA4
Stent graft design provides unique benefits to the treatment of lesions refractory to PTA
- Expanded PTFE (ePTFE) flow lumen covers and seals off diseased tissue
