Long-term outcome of percutaneous exclusion of huge saphenous vein graft aneurysms using peripheral covered-stents as alternative to surgical repair.

Giant vein graft aneurysms occur infrequently after coronary artery bypass graft surgery and are most often detected incidentally during coronary angiography for suspected angina or as a mediastinal mass on chest radiographs. Hereby, we describe the percutaneous treatment of a huge right coronary artery saphenous vein bypass graft aneurysm by using peripheral stent-graft. Twelve months after the procedure, the aneurysm was completely sealed at computed tomographic angiography with a good distal run-off in the bypass graft. Different strategies adopted and the feasibility as well as the long-term outcomes of this technique are described thoroughly.
