Dysphagia associated with an aortic arch anomaly in adults.
Aortic arch anomalies typically become evident in early childhood with clinical manifestations such as cyanosis and feeding problems. Although uncommon and therefore not often considered, this developmental defect can cause dysphagia in the adult. The double aortic arch is the most common vascular ring in infants. Less well-known vascular rings in the adult are a right aortic arch with constricting left ligamentum arteriosum and an aberrant right subclavian artery. Dysphagia is common secondary to the constriction of the esophagus. Two patients recently presented to the Metropolitan Nashville General Hospital with prolonged history of dysphagia. Studies included barium swallow and aortogram, which showed right aortic arch in both patients with constricting left ligamentum arteriosum. The treatment for these symptomatic anomalies was division and excision of the ligamentum arteriosum and freeing of the esophagus. A right aortic arch on the chest roentgenogram in a patient with dysphagia should suggest a vascular ring as the etiology. If this is suspected, diagnosis is easily made and surgical treatment is effective. The relevant embryology will be discussed.
