In infants, the trachea is compressible; therefore, the typical signs and symptoms compression by arteria lusoria are respiratory, such as wheezing, stridor, recurrent pneumonia, and cyanosis.
However, Branscom and Austin  noted that abnormalities of the aortic arch in a chest X-ray picture were found in only 20% of cases with an arteria lusoria.
According to the literature, only 60% of procedures using a transradial approach were successful in the presence of an arteria lusoria .
It is important to remember that common conditions such as shortness of breath, retrosternal pain, cough, and weight loss may be symptoms of the compression of adjacent structures by the arteria lusoria. The presence of the ARSA, especially, should be taken into consideration to distinguish from other causes of dysphagia.
