Subclavian artery stenosis: A case series and review of the literature

Abstract

Subclavian artery stenosis (SAS) is a significant form of peripheral artery disease, which may be a marker of diffuse atherosclerosis and increased risk for cardiovascular events. SAS can lead to symptomatic ischemia affecting the upper extremities, the brain, and, in some cases, the heart. In general, asymptomatic subclavian artery disease is treated with medical therapy and invasive treatment is reserved for the more symptomatic patients. This article discusses the evaluation of four patients with varying presentations of subclavian artery disease. © 2014 MedReviews®, LLC.
