Arteria lusoria

Arteria lusoria is the designation of aberrant distance of the right a. subclavian'. It departs as the last branch of the aortic arch behind the left a. subclavian, or from the descending part of the aorta. It passes through the posterior mediastinum usually behind the esophagus and its oppression causes dysphagic difficulties (so-called ''dysphagia lusoria') '), exceptionally it can also go between the esophagus and the trachea, thus oppressing the airways and causing a prolonged cough in infants. With its distance, it can also oppress the n. laryngeus recurrentens sinister' and lead to Ortner's syndrome. Aberrant spacing can also be associated with the so-called Kommerell's diverticulum.
