Resumen de Retro-oesophageal right subclavian artery associated with a non-recurrent laryngeal nerve - case report
Chinnawut Suriyonplengsaeng, Krai Meemon
A retro-oesophageal right subclavian artery (RRSA) was detected in an 81-year-old Thai male cadaver. It originated from the proximal thoracic aorta and ascended posterior to the oesophagus continuing as the axillary artery beyond the level of the right first rib. Abnormal vascular branches and a right non-recurrent inferior laryngeal nerve were associated with the RRSA. Moreover, the ansa subclavia was prominently discernible to enclose the RRSA. The embryonic development and associated anatomical variations of the RRSA are discussed.
