          Abstract

          Resumen Introducción: la arteria subclavia aberrante es la anomalía más común del arco aórtico, aunque la clínica de disfagia lusoria aparece tan solo en el 0,5-2 % de los pacientes. No existe ningún consenso sobre su tratamiento. Caso clínico: se presenta el caso de una paciente de 86 años con clínica de disfonía y disfagia de 1,5-2 años de evolución que asocia una pérdida de peso de 10 kg en los últimos 6 meses. En el escáner realizado durante el estudio se encuentra una arteria subclavia aberrante no dilatada que comprime el esófago a su paso retrocardial. Además, la paciente presentaba una estenosis del 60 % de la arteria carótida ipsilateral que le había ocasionado un ictus 5 meses antes. Se realiza un bypass carótido-subclavio derecho con prótesis PTFE de 6 mm y en la misma intervención, tras el procedimiento anterior, se realiza una endarterectomía carotìdea derecha y angioplastia quirúrgica. El posoperatorio transcurrió sin complicaciones. La paciente se mantuvo asintomática, sin eventos neurológicos; tampoco disfagia ni disfonía. Pudo retomar la ingesta normal de alimentos. En el CT de control a los 10 días se observó la arteria subclavia derecha trombosada sin compresión residual, por lo que no se consideró necesaria la exclusión de su origen con una endoprótesis torácica. Discusión: aunque en un primer momento se consideró la posibilidad de realizar un tratamiento en dos tiempos (cirugía abierta y, posteriormente, endovascular torácico), el tratamiento quirúrgico combinado permitió tratar la disfagia lusoria, así como la estenosis carotídea sintomática ipsilateral, durante la misma intervención para no tener que someter a una paciente mayor a una cirugía excepcionalmente larga, además de omitir el uso de una endoprótesis torácica complementaria que finalmente no fue necesaria.

          Abstract Introduction: the aberrant subclavian artery is the most common variation of the aortic arch but symptoms of dysphagia lusoria appear only in 0,5-2 % of the patients. There is no consensus on its treatment. Case report: we hereby present the case of an 86 year-old woman who had suffered dysphonia and dysphagia for 1.5-2 years associating a loss of 10 kg of weight in the last 6 months. An angioCT scan revealed a non-dilated aberrant right subclavian artery which compressed of the retrocardial esophagus, and a 60 % stenosis of the right carotid artery, which had caused an ipsilateral minor stroke 5 months before. We performed a right carotid-subclavian bypass using a 6 mm ePTFE graft, followed by a right carotid endarterectomy and Dacron patch angioplasty in the same procedure. The postoperative period was uneventful, the patient remained asymptomatic, with no neurological symptoms, dysphagia or dysphonia, and resumed normal oral intake. Ten days after the procedure the control CT revealed a thrombosed right subclavian artery with no residual esophageal compression, so an additional endovascular occlusion of the subclavian origin was deemed unnecessary. Discussion: although we first considered the possibility of performing a sequential hybrid treatment, with initial surgical bypass and secondary thoracic endovascular grafting, the combined open surgical technique allowed us to solve both the dysphagia lusoria and the symptomatic right carotid stenosis in one single procedure, and the complementary thoracic endografting was ultimately unnecessary.

          Aberrant subclavian artery: anatomical curiosity or clinical entity.

          Dysphagia lusoria, caused by aberrant subclavian artery, is an uncommon cause of dysphagia. When present it is mostly asymptomatic. Barium esophagogram may indicate the presence of this anomaly. Diagnosis needs to be confirmed by CT/MRI prior to any intervention. No treatment is required for asymptomatic patients. If causing significant symptoms, operative management offers definitive treatment. The choice of treatment depends on local expertise, equipment and experience of the surgical team. However, for those who are unfit or refuse operative intervention, there is a role for symptomatic and supportive treatment. Our cases demonstrate three different manifestations of this single entity.
