Abstract:
Brachiocephalic and subclavian artery stenoses are less common manifestations of peripheral arterial disease (PAD) compared to lower extremity PAD. However, even among asymptomatic patients, a diagnosis of PAD portends worse long-term mortality. Symptoms may include subclavian steal syndrome and arm claudication. Among patients with internal mammary coronary bypass grafts, symptoms may include those of myocardial ischemia. Symptomatic subclavian stenosis can be readily treated using endovascular techniques with durable outcomes.
