Aberrant right subclavian artery intervention can provide relief of dysphagia.

Abstract

Background: An aberrant right subclavian artery represents the most common aortic arch vascular anomaly. Conventional wisdom states that these anomalies do not result in dysphagia, but rather serve as "red herrings". Clearly, in the vast majority of cases, this holds true. Nonetheless, one should never say never.

Methods: Herein, we present a cohort of four children with debilitating dysphagia resulting from an aberrant right subclavian artery. Subclavian reimplantation via a right posterolateral thoracotomy was performed successfully in all cases.

Results: Dysphagia resolved postoperatively, and all patients were able to advance to a normal diet. They were able to gain appropriate weight postoperatively and continue to do well at most recent clinical follow-up.

Conclusions: This case series suggests that aberrant right subclavian artery anatomy should be considered a potential aetiology of dysphagia, albeit rarely. Surgical intervention for select patients can provide dramatic resolution of symptoms.
