title: Symptomatic aberrant retro-esophageal subclavian artery: considerations about the surgical approach, management and results.
abstract: Ten case histories of patients with symptomatic aberrant retro-esophageal subclavian artery are presented. The diagnosis was made on a clinical basis in 8 cases because of symptoms of tracheo-esophageal obstruction, and confirmed by barium meal. All patients were investigated by angiography. Six patients with right abnormal retro-esophageal subclavian artery (arteria lusoria) and its mirror image were treated by transection of the aberrant subclavian artery and reimplantation into the common carotid artery through a single midline sternal splitting incision which gave ample access. Three patients with left abnormal subclavian artery (right aortic arch) were operated by transection of the patent ductus arteriosus or ligamentum arteriosum through a left lateral thoracotomy. After a follow-up of from one to 10 years (mean 6.4 years), 9 patients are free of symptoms like dysphagia, dyspnea or subclavian steal and normal pulses are present on both upper extremities in 8 cases.
