ABSTRACT

Introduction: dysphagia lusoria is an infrequent cause of mechanical dysphagia caused by extrinsic compression.
Clinical case: it was studied a patient admitted because a dysphagia with clinical suspect of esophageal neoplasm. An esophagogram was performed, patient was not collaborative, it was not possible to opacify esophagus in its whole extension, it was observed a defect of irregular fullness in its third superior suggesting esophageal neoplasm. It was decided to confirm diagnosis using endoscopy of high digestive way. There was no observation of lesions at esophagus level, but the presence of chronic gastroduodenitis signs and mild gastroesophagic reflux. Because of the controversial results in both studies and patient symptoms, a contrasted tomography of mediastinum was performed.
Discussion: the presence of an anomalous vessel at the level of the aortic arch measuring 17,89 mm in the right, posterior to esophagus compressed esophagus and moved it to the front and to the right. In multiplanar reconstruction corresponds to a right aberrant subclavian artery.
Conclusion: dysphagia lusoria is the most frequent anomaly in the development of the aortic arch. These aberrant arteries tend to dilate and can be complicate with thromboembolic phenomena in the right superior extremities or with rupture. Besides, it can be associated to other alterations of the development of the aortic arch or with the descendent aorta, as an aortic coarctation.
