The right subclavian artery originates from the innominate artery. The right subclavian artery arises from the unnamed artery that is partially divided into the cephaloarterial trunk and the aortic arch. The innominate artery descends and divides into the right subclavian artery and the right carotid artery. The right subclavian artery can continue to differentiate into the right common carotid artery, migratory axillary artery, brachial artery, radial artery, ulnar artery, and so on. The right subclavian artery is a very important blood vessel as it mainly supplies the blood supply to the right upper limb. The right subclavian artery emanates directly up to the neck area and the subclavian travels laterally. The “three highs” of high fat blood, high blood pressure, high blood sugar, smoking, obesity and other factors can lead to the formation of plaque in the right subclavian artery. Normally, we should pay attention to develop a good dietary habits, regular physical examination, exclude vascular lesions.
