Conservative Management of Aberrant Right Subclavian Artery (Arteria Lusoria): A Case Report and Literature Review

The most common embryological aortic arch abnormality is the aberrant right subclavian artery (ARSA), also known as arteria lusoria or dysphagia lusoria. Arteria lusoria is commonly associated with vascular anomalies, including truncus bicaroticus, right-sided aortic arch, and Kommerell's diverticulum (KD), predisposing to complications like acute aortic syndrome. Surgical intervention is usually reserved for symptomatic patients with compressive and/or hemodynamic alterations. However, there is no consensus on its clinical management and subsequent follow-up. Here, we present the case of a 71-year-old symptomatic elderly female with arteria lusoria who was managed conservatively. We believe conservative management is a viable option, especially in elderly patients, which should be supported with regular surveillance to detect any complications that necessitate surgical intervention.
