Abstract
- Aberrant right subclavian artery (ARSA) is an anomaly with a reported incidence of 0.5% to 2%. Most patients with an ARSA remain asymptomatic; however about 10% of adult patients have compressive symptoms. A case is reported of a 64-year old female patient who had a few years of history of dysphagia and recurrent pneumonia. Angiography was performed, which demonstrated an ARSA with common origin of the right and left carotid arteries. Surgical correction was performed via right thoracotomy. The proximal aberrant artery was mobilized behind the esophagus. The distal, right subclavian artery was exposed, transected, and transposed with reimplantation into the aortic root by graft bypass.
