Dysphagia secondary to aberrant right subclavian artery

Left aortic arch with aberrant right subclavian artery is the most frequent anomaly of the aortic arch. Prenatal diagnosis through echographic imaging has allowed early diagnosis, but the entity still remains mainly an incidental finding. Most cases are asymptomatic, but a subset of patients suffer from dysphagia with the intake of solid food. In a small percentage it can cause poor weight gain or respiratory symptoms secondary to extrinsic compression of the airway. Diagnosis relies usually in oesophagography with barium contrast, although computerized tomography and magnetic resonance with angiography have also shown to be useful, as well as echocardiogram with colour Doppler. Surgery is the preferred treatment option for symptomatic patients.
