  • Title: Restenosis following subclavian artery angioplasty for treatment of coronary-subclavian steal syndrome: definitive treatment with Palmaz-stent placement.
    Author: Mufti SI, Young KR, Schulthesis T.
    Journal: Cathet Cardiovasc Diagn; 1994 Oct; 33(2):172-4. PubMed ID: 7834733.
    Abstract:
    We report a case of progressive angina pectoris 4 years post coronary bypass surgery, in which the left internal mammary artery (LIMA) was grafted to the native left anterior descending coronary artery. The coronary-subclavian steal phenomenon was proven angiographically with retrograde reflux through the LIMA graft into the distal subclavian vessel, downstream from a critical stenosis at the origin of the subclavian artery. After initially successful angioplasty of the ostial subclavian lesion, restenosis and return of angina prompted repeat dilatation and placement of a Palmaz 154-M stent. Follow-up catheterization has demonstrated persistent patency at the stented site and absence of coronary steal.
