Coronary angiography was performed in three cases with recurrent angina pectoris who had undergone previous CABG operation. In three cases coronary angiography demonstrated retrograde filling of the LIMA toward its origin from subclavian artery. In two cases left subclavian artery was totally occluded, but in one case it was subtotally occluded. In two cases carotid-subclavian by-pass (with 6 mm Gore-Tex graft) and in one case subclavia-subclavian by-pass (with 7 mm Hemashield graft) was performed. Ischemic symptoms disappeared in two patients and became less severe in the other Coronary-subclavian steal syndrome should be taken in to consideration in recurrent ischemia after CABG when LIMA is used as a conduit.
