title: [Treatment of subclavian artery stenosis with stents in patients previously treated with internal mammary left anterior descending artery bypass surgery].
abstract: We reported two cases of patients that underwent left internal mammary (LIMA)-coronary bypass graft and developed recurrent myocardial ischemia in the follow-up period caused by stenosis in the subclavian artery. The angiography showed retrograde flow from the left anterior descending artery to subclavian artery. After initial dilatation with a conventional angioplasty balloon catheter, we implanted Palmaz-Schatz Stents, achieving an excellent final result. Our finding suggest that Stent implantation is a safe and effective procedure, and provides an alternative to other forms of revascularization for the treatment of this disorder.
