This condition is usually asymptomatic. The<unk>  artery usually arises just distal to the left<unk>  artery and crosses in the posterior part of the mediastinum on its way to the right upper extremity. In 80% of individuals it crosses behind the esophagus. Such course of this<unk>  vessel may cause a vascular ring around the trachea and esophagus. Dysphagia due to an<unk>  right<unk>  artery is termed dysphagia lusoria, although this is a rare complication. In addition to dysphagia,<unk>  right<unk>  artery may cause stridor, dyspnoea, chest pain, or fever. An<unk>  right<unk>  artery may compress the recurrent laryngeal nerve causing a palsy of that nerve, which is termed Ortner's syndrome. The<unk>  right<unk>  artery frequently arises from a dilated segment of the proximal descending aorta, the so-called Diverticulum of Kommerell (which was named for the German radiologist Burkhard Friedrich Kommerell (1901–1990), who discovered it in 1936). It is alternatively known as a lusorian artery.
