A 66 year-old woman underwent coronary artery bypass grafting for postinfarction angina. A left internal mammary artery graft was joined to the left anterior descending artery. Coronary and graft angiography revealed a 90% stenosis in the anastomotic site of the left internal mammary artery. During PTCA with a 2.0 mm balloon catheter, acute occlusion of the graft body occurred. Intragraft injection of isosorbide dinitrate failed to dilate the graft. Thus, careful consideration should be given to several complications such as acute occlusion of the graft when PTCA for anastomotic site of the graft is performed.
