Abstract
IntroductionAnatomically, the aberrant subclavian artery is the last branch of the aortic arch. On its way to the right upper limb it runs posterior to the esophagus. During this passage it can compress the esophagus, producing Lusoria Dysphagia.Materials and methodsDifferent databases were subjected to a systematized literature search, using the following criteria: articles published between 2000 and 2020, and articles that established a clinical correlation between an aberrant subclavian artery and Lusoria Dysphagia.ResultsAfter full text analysis of the articles that met the criteria, 48 articles were found in which three types of aberrant arteries were identified. These were associated with symptoms of Dysphagia Lusoria in the subjects of the analyzed studies. The most common type of variation in the origin of the aberrant artery was Type I, an aberrant right subclavian artery that arises as the last branch of the aortic arch, maintaining the origins of the other branches of this arch. The most common course was retroesophageal, which was most commonly associated with the symptoms of patients with Dysphagia Lusoria.ConclusionsThe knowledge of the variations and courses of these types of aberrant arteries and their clinical associations is relevant for specialist professionals who treat patients diagnosed with Dysphagia Lusoria.
