Treatment of post-stenotic saphenous vein graft aneurysm: special considerations with the polytetrafluoroethylene-covered stent.

The use of the polytetrafluoroethylene-covered stents is expanding and its full potential in percutaneous coronary intervention is still being defined. The synthetic covered stent has been used in the treatment of coronary as well as saphenous vein graft disease. In the treatment of relatively large aneurysms of saphenous vein grafts, however, the technical and anatomic aspects may be unusual and challenging. We present a case of an ostial saphenous vein graft lesion with a saccular post-stenotic aneurysm treated with a polytetrafluoroethylene-covered stent. Special consideration is made of the procedural technique and the unusual anatomic challenge.
