Arteria Lusoria: An Uncommon Cause of Dysphagia

Abstract

N/a.

Diagnostic Challenge in a Symptomatic Patient of Arteria Lusoria with Retro-esophageal Right Subclavian Artery and Absent Brachiocephalic Trunk

“…The presence of a retro-esophageal right subclavian artery arising from descending aorta in association with an anomalous right circumflex artery with absent innominate artery is an extremely rare finding when found as a combination [2][3][4]. This variant of aortic arch anomalies can pose a diagnostic challenge due to nonspecific symptom presentation leading to routine invasive procedure which may end up being technically difficult and risky intra-operatively [3][4][5][6][7]. Routine femoral catheterization may fail to depict this important anatomical variation.…”

“…Most of such patients do not have active symptoms. However depending on the anomaly, these anatomical variations can clinically manifest as gastrointestinal (GI) symptoms including episodic dysphagia and regurgitation, cardiac symptoms including atypical chest pain or angina, and respiratory symptoms like chronic cough, aspiration, and bronchiectasis [5][6][7][8].…”
