A case of aberrant right subclavian artery with the development of Bayford–Autenrieth dysphagia

Abstract

   Developmental anomalies of the aortic arch and its large vessels can be accompanied not only by hemodynamic disorders, but also affect the functions of internal organs. This report analyzes the case of an autopsy finding of the right aberrant subclavian artery in an 80-year-old patient, which was clinically manifested by the development of dysphagia and cachexia. An autopsy revealed the absence of the brachiocephalic trunk, which normally originates from the arch of the authors, as well as an abnormal origin of the right subclavian artery from the posterior surface of the aortic arch, 1,1 cm to the left and distal to the orifice of the left subclavian artery. The proximal segment of the abnormal vessel, up to 1,0 cm in diameter, was located between the spinal column and the esophagus, leading to its compression.
