[Saphenous vein to saphenous vein bypass grafting in four redo CABG patients].

In four redo CABG patients, new saphenous vein grafts were anastomosed to the angiographically normal part of the old, and partially narrowed or occluded saphenous vein grafts in an end-to-side fashion. Inner surface of the old saphenous vein was confirmed to be smooth and free of atherosclerotic change during anastomosis. Postoperative course was uneventful and angiography demonstrated the good patency of new saphenous vein grafts in all patients. Although this technique is not acceptable if the old saphenous vein graft shows extensive atherosclerotic change, this method may be a useful alternative in case of limited saphenous vein graft disease in terms of less difficulty and operation time.
