Case Discussion
Aberrant right subclavian artery (with a normal left-sided aortic arch) is seen in 1% of patients.
The aberrant right subclavian artery travels posterior to the esophagus, which appears on an upper GI study as a posterior smooth esophageal indentation.
It is almost asymptomatic.
If there is an impairment of swallowing as a symptom, it is called dysphagia lusoria, and appears as a result of compression of aberrant right subclavian artery on esophagus.
