[Angina pectoris due to coronary-subclavian steal syndrome caused by the LIMA graft in the patient after CABG with the use of the right and left mammary artery].

We present a case of a patient with unstable angina pectoris two years after coronary artery by-pass graft surgery with the use of the right and left mammary artery. The symptoms were caused by the critical RIMA stenosis and coronary-subclavian steal syndrome through the LIMA graft. Unsuccessful attempt of percutaneous angioplasty of the closed left subclavian artery was made. The angioplasty of the proximal part of the RIMA with the implantation of a drug eluting stent followed by the angioplasty of both left circumflex artery and obtuse marginal artery with the implantation of bare metal stents was performed. These procedures resulted in disappearance of anginal symptoms. Neurological examination did not reveal any signs of vertebrobasilar steal.
