title: Innovative use of self-expanded polytetrafluoroethylene endoprosthesis for percutaneous endovascular interventions.
abstract: VIABAHN® endoprosthesis (Gore & Associates, Flagstaff, AZ), a nitinol self-expanding polytetrafluoroethylene (PTFE) lined stent, has demonstrated utility for percutaneous treatment of chronic occlusive disease involving the superficial femoral artery. In a case series communication we aimed to describe the feasibility of a PTFE-lined stent for percutaneous treatment of conditions other than chronic occlusive disease. We report the successful use of PTFE-endoprosthesis to percutaneously treat several vascular conditions, including arterio-venous fistula closure, reconstruction of a distal limb of an aorto-femoral endoprosthesis aneurysm, femoral artery perforation repair, and an exclusion of large saphenous vein graft aorto-coronary bypass aneurysm. This case series illustrates the feasibility of the "off-label" use of self-expanded PTFE endoprosthesis to percutaneously treat several conditions, which would otherwise require "open" surgical reconstructions.
