Retroesophageal Right Subclavian Artery

Abstract

During routine dissection of head and neck region in a 65-year-old female cadaver variation in the origin of right subclavian artery was found. The right subclavian artery originated as a direct branch of arch of aorta distal to the origin of left subclavian artery and it was found passing behind esophagus (retroesophageal) and ascending upwards to the right side while the left subclavian artery originated normally from arch of aorta distal to the origin of left common carotid artery. Anomalous variations in the origin and course of arteries have serious implications in angiographic and surgical procedures; hence it is of great importance to be aware of such possibilities of variations.

“…6 This anomaly can also lead to ischaemia of the upper limb and about 5% of these patients will present with airway compression symptoms. 8 Prevalence of aberrant subclavian artery in right NRLNs is 89.3%. 2 Our patient did not show dysphagia lusoria or any other symptoms and therefore investigations to detect the vascular anomaly were not done.…”

A rare case of a blunt thoracic aortic injury in a patient with an aberrant right subclavian artery: A case report and literature review

“…She had an aberrant right subclavian artery in which the right subclavian artery originated from the aortic arch distal to the left subclavian artery and traveled in the retro-esophageal region towards the patient’s right side. While overall a rare entity, aberrant right subclavian artery is the most common abnormality of the aortic arch with a prevalence of 0.4%–2%, with 15% accounting for a retro-tracheal course and the rest of the aberrant right subclavian arteries taking the retro-esophageal course [ 9 , 14 ]. In addition, after her index operation, she required two further procedures to manage a type II endoleak.…”

“…Other symptoms can be asymmetric pulses and blood pressure in the upper limbs, trophic changes in the respective limb, and even acute ischemia of the right upper limb (16,20). Awareness of such variations has a significant role during angiography and Doppler scanning of blood vessels (16,(21)(22)(23).…”
