Introduction:

Anatomically, 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 methods:
Different 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. 

Results:
After 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.

Conclusions:
The 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.





Types of origin of AL. Type I corresponds to an aberrant right subclavian artery that arises as the last branch of the aortic arch, maintaining the origin of the other branches of this arch. Type II corresponds to an aberrant left subclavian artery associated with a bicarotid trunk, formed by both common carotid arteries. Type III is a mirror of the type I pattern: a right aortic arch from which a subclavian artery arises with a retroesophageal path; Fig. 3: Types of course of the AL. A. Retroesophageal course. B. Course between the trachea and the esophagus. C. Course anterior to the trachea.
