Symptomatic vascular rings causing late-onset dysphagia (dysphagia lusoria) are quite unusual in adults. We present a 42-year-old woman with a 1-year history of dysphagia from a right-sided aortic arch with an aberrant left subclavian artery and left-sided ligamentum arteriosum. Using a helical CT scan of the chest and a three-dimensional reconstruction software, her anatomic abnormality was completely delineated. Arch aortogram confirmed the anomaly. The patient underwent a left posteriolateral thoracotomy. Intraoperative findings correlated precisely with the preoperative reconstruction data. Division of the ligamentum resulted in a complete decompression of the esophagus and resolution of the patient's symptoms.
