Methods: Percutaneous transluminal angioplasty was performed on six patients with severe left subclavian artery stenosis proximal to the origin of the vertebral artey for upper extremity claudication.
Results: In our cases , reversal of blood flow was caused through the left vertebral artery due to the lesion . In all six patients , selective left subclavian angiography showed stenosis proximal to the origin of the vertebral artey.
Conclusions: Percutaneous transluminal angioplasty of the subclavian artery is a safe and effective method in the treatment of subclavian steal syndromes and should be considered as the treatment of choice.
