The right subclavian artery vagus is a congenital developmental malformation of the artery with a prevalence of 1-2%, most patients have no obvious discomfort, and only about 10% have symptoms of esophageal compression. The right subclavian artery vagus is an artery that originates from the aortic arch and enters the right upper extremity around the back of the esophagus. The malformation usually has no obvious discomfort, and very few patients may have esophageal swallowing disorder, which is caused by the compression of the esophagus by the vagus artery. For asymptomatic vagus artery does not require any treatment, while for patients with obvious discomfort, no effective conservative treatment measures are available and surgical treatment is often required to relieve esophageal compression, which is a more mature treatment technique with little risk and better surgical results.
