Percutaneous angioplasty and stenting of left subclavian artery lesions for the treatment of patients with concomitant vertebral and coronary subclavian steal syndrome.
OBJECTIVE
To evaluate the efficacy of subclavian stenosis percutaneous transfemoral angioplasty (PTA)-treatment in patients with intermittent or complete subclavian steal syndrome (SSS), and coronary-subclavian steal syndrome (C-SSS) after left internal mammary artery-interventricular anterior artery (LIMA-IVA) by pass graft.


METHODS
We studied 42 patients with coronary subclavian steal syndrome subdivided in two groups; the first group consisted of 15 patients who presented an intermittent vertebral-subclavian steal, while the second group consisted of 27 patients with a complete vertebral-subclavian steal. All patients were treated with angioplasty and stent application and were followed up for a period of 5 years by echocolordoppler examination to evaluate any subclavian restenosis.


RESULTS
Subclavian restenosis was significantly increased in patients with a complete subclavian steal syndrome. The restenosis rate was 6.67% in the first group and 40.75% in the second group, These patients had 9.1 fold-increase risk (CI confidence interval 0.95-86.48) in restenosis.


CONCLUSIONS
Patients with a complete subclavian and coronary steal syndrome present a higher risk of subclavian restenosis.
