Percutaneous transluminal angioplasty for atherosclerotic stenosis of the subclavian or innominate artery: angiographic and clinical outcomes in 36 patients.
The purpose of the study was to evaluate stenting and percutaneous transluminal angioplasty (PTA) for the treatment of stenotic lesions of the subclavian or innominate artery based on surgical results and long-term follow-up with 36 patients. In particular, we evaluated the efficacy of self-expanding stents compared to balloon-expandable stents. Between February 2000 and March 2008 at the Kyoto Medical Center, 36 patients underwent both stenting and PTA of the subclavian or innominate artery. ⋯ Restenoses occurred in 4 of 20 individuals (20%) who received balloon-expandable stents but were not observed in those who received self-expanding stents. Endovascular therapy for the subclavian and innominate arteries is less invasive and safer than open surgery, making it the preferable option. In this clinical period, the rate of restenosis using self-expanding stents was lower than the rate using balloon-expandable stents.
