title: A case with spasm of a saphenous vein graft.
abstract: A 54-year-old man developed angina pectoris 18 months after a successful aortocoronary bypass graft. The angiogram demonstrated patent grafts and no significant changes in the native coronary vessels. However, ergonovine maleate provoked spasm in a saphenous vein graft.
