Introduction: Takayasu's arteritis (TA) is a chronic, idiopathic, inflammatory disease that affects large elastic arteries, including the aorta and its main branches. No consensus exists currently on the superiority of surgery over endovascular repair (angioplasty with or without stenting) for vascular lesions in TA. Case Presentation: A 54-year-old woman with an 11-year history of ankylosing spondylitis (AS) presented with left arm weakness and severe left arm claudication. Duplex ultrasonography of the left upper extremity showed vessel-wall edema of the subclavian, axillary, and brachial arteries. Aortic angiography demonstrated a 70 - 80% stenosis of the left subclavian artery and a long, high-grade stenotic segment of the axillary artery. Intravascular ultrasound (IVUS) of the stenotic subclavian segment showed extensive negative remodeling with minimal plaque formation. The patient responded well to balloon angioplasty on this segment with medical therapy for AS. Conclusions: Our case is the first report of IVUS imaging of subclavian stenosis resulting from Takayasu's arteritis and provides insight into the pathology behind such lesions.
