Objective: We report two cases of atherosclerotic vertebral and subclavian stenosis presenting with subclavian steal syndrome.Case presentation: Two patients, who had symptoms of upper extremity weakness and vertebrobasilar insufficiency, underwent stent replacement for obstructive lesions of the subclavian and vertebral arteries. Stents were successfully placed in both, resulting in resolution of symptoms. Conclusion: Surgical revascularization techniques, bypass graft and endarterectomy, have been the mainstay treatment for vertebral and subclavian stenosis, but the morbidity rate associated with surgical treatment was relatively high. Recently, the endovascular treatment has been widely used for stenotic lesions and associated with a high rate of technical success. In two cases, we used new stents that did not require a system for remounting. These new devices solve the problem of balloon injury during catheter insertion, passage through the stenotic lesion, and stent placement except at the site of the target lesion. Endovascular treatment for obstructive lesions of the subclavian and vertebral arteries is considered to be a feasible and safe treatment and may be effective for stroke prevention.
