Abstract

Aberrant right subclavian artery (ARSA) is a congenital anomaly with a reported frequency of 0.5-1% and generally shows an asymptomatic clinical course. Being rare and usually asymptomatic complicates diagnosis and treatment. Although respiratory symptoms are rare in ARSA, chronic cough may be a symptom for diagnosis. Cases with chronic cough that persists despite treatment should be evaluated using posteroanterior chest X-ray and, if necessary, thorax computed tomography. In our article, we presented a case of a patient who applied to our family medicine outpatient clinic with a complaint of chronic cough and was diagnosed with ARSA.
