Subclavian arterial stent implantation is associated with better 1-year patency than PTA due to improved technical success, but intermediate and long-term outcomes are less favorable, as instent restenosis frequently occurs.

Endovascular revascularization improves the long-term hemodynamic outcome in patients with subclavian stenosis, but many conservatively treated patients become asymptomatic during follow-up. Interventional treatment may be considered primarily for patients with severe symptoms of vertebrobasilar insufficiency, critical ischemia, or peripheral emboli.
