Aberrant right retroesophageal subclavian artery causing esophageal compression

Dysphagia lusoria is present in 0.2–2.5% of the population representing the most common anomaly of the aortic arch (De Araújo et al., 2015, Int. J. Surg. Case Rep., 7, 32). It usually presents in infants, but can present at any age. Symptoms include cough, dysphagia, thoracic pain, and pulmonary infection. Barium contrast studies, CT, and MR angiography are useful studies for evaluating the condition. Dietary modification and PPI therapy are the first-line treatments with surgical intervention reserved for those with ongoing symptoms (Janssen et al., 2000, Am. J. Gastroenterol., 95, 1411).
