[2][3] In addition to dysphagia, aberrant right subclavian artery may cause stridor, dyspnoea, chest pain, or fever.

[3] An aberrant subclavian artery (ASA) is commonly diagnosed through imaging studies that visualize the structure and origin of blood vessels.

Here are the primary diagnostic tools used: Echocardiography: Especially in infants, an echocardiogram may initially detect abnormal vessel placement.

Barium Swallow Study: If there are symptoms like dysphagia, this test can reveal if the esophagus is compressed by the aberrant artery, suggesting the presence of a vascular ring.

Each of these techniques provides unique insights into the vascular structure, helping determine the presence, orientation, and potential impact of an aberrant subclavian artery.
