Axillo-axillary bypass with polytetrafluoroethylene graft for coronary subclavian steal syndrome.

The purpose of this study is to report the results of axillo-axillary bypass (AAB) for coronary subclavian steal syndrome due to proximal subclavian artery occlusion. From 2003 to 2010, AAB using a polytetrafluoroethylene (PTFE) graft was performed in 11 patients with coronary subclavian steal syndrome. There was no perioperative mortality, stroke or cardiac complications. Over a mean follow-up of 36 months (range: 6-81 months), all bypass grafts have remained patent. No patient developed recurrent symptoms of myocardial ischemia. One patient died from hemorrhagic stroke at 31 months. Our results showed that AAB using a PTFE graft provides an effective and durable treatment option for coronary subclavian steal syndrome when attempted endovascular therapy of the occluded proximal subclavian artery is unsuccessful.
