Aberrant right subclavian artery (ARSA) is the most common embryological abnormalities of the aortic arch. It is seen 0,5-1,8 per hundreds overall the population. Aberrant right subclavian artery can be seen asymptomatic in infants; whereas it can also occur severe symptoms such as respiratory distress, stridor, wheezing, dyspnea, dysphagia, recurrent lung infections due to compression on trachea, main bronchi and esophagus. We report a three month- old girl who received a long-term treatment due to recurrent pneumonia with atelectasis. Without any etiological abnormalities about recurrent pneumonia, aberrant right subclavian artery that was compressing right main bronchia, right upper bronchi, and right pulmonary artery was detected via cardiac catheterization. We aimed to emphasize the possibility of aberrant right subclavian artery in who have recurrent or non-healing pneumonia without any etiology despite receiving long-term treatment.
