Dysphagia lusoria--report of 2 cases and a review of the literature.

140 Aberrant subclavian artery is the most frequent aortic arch anomaly and occurs in 0.5% of normal individuals. The majority of people with this anomaly are asymptomatic and nothing needs to be done. However, cervicomediastinal surgery for unrelated conditions predisposes patients to potential morbidity and even fatal outcomes. This paper describes the management of two symptomatic patients, with a literature review.
