A Case Report on Aneurysm of the Atypical Right Subclavian Artery: A Rare Embryological Aberration

Atypical or an aberrant right subclavian artery, is the most prevalent vascular anomaly of the aortic arch but a rare embryological aberration. It is typically discovered by accident during imaging tests or autopsy and is usually asymptomatic. Dysphagia and dyspnea are the most common symptoms, which arise when the abnormal artery compresses the surrounding structures. It could be linked to further cardiac or vascular anomalies. We are presenting an 86-year-old woman who has an aneurysm connected to her atypical right subclavian artery. In order to prevent surgical complications, clinicians who undertake thoracic diagnostic and surgical procedures in thorax should pay special attention to the unusual or aberrant right subclavian artery.
