title: Right aortic arch with aberrant left subclavian artery: aneurysmal dilatation causing symptomatic compression of the right main bronchus in an adult.
abstract: A 60-year-old woman presented with a cough, nocturnal stridor and dysphagia. Bronchoscopy showed tight compression of the right main bronchus. Digital subtraction angiography (DSA) and a computed tomographic (CT) scan showed the presence of a right-sided aortic arch with aberrant left subclavian artery. The distal right arch and proximal right-sided descending thoracic aorta were aneurysmal and were responsible for this compression. Surgical relief was accomplished by dividing the aberrant left subclavian artery and replacing the aneurysm with a vascular graft.
