[Postoperative percutaneous coronary angioplasty for stenosed aortocoronary vein bypass]

This paper was presented to demonstrate the efficacy of postoperative PTCA for varying degree of stenosis aortocoronary bypass with saphenous vein grafts. The following conclusions were drown. 1. The success rate of postoperative PTCA for 15 grafts showed 88.8%. 2. The rate of success for PTCA was much more effective in patients within one year after bypass operations. The authors concluded that postoperative PTCA can be done with excellent rate of success. Therefore, postoperative cine-coronary angiography should be done to evaluate the state of the graft and to decide to perform possible postoperative PTCA in order to keep long time patency rate of saphenous vein grafts.
