Aberrant right subclavian artery or arteria lusoria: a rare cause of dyspnea in children

Abstract

Aberrant right subclavian artery or arteria lusoria (AL) is the most frequent anomaly of the aortic arch, secondary to abnormal embryogenesis. It is usually asymptomatic and fortuitously discovered. It can compress neighboring structures and cause dysphagia or, more rarely, dyspnea. In symptomatic cases or in the presence of an aneurysm of the AL origin, it should be surgically treated. The case herein reported concerns a child presenting with respiratory symptomatology related to an AL that was surgically treated by right supraclavicular approach.
