The left thoracotomy approach for excision of distal tracheal carcinoma in the presence of right-sided aorta.

Tracheal primary carcinoma is a rare malignancy, and we believe that its presence in a patient with a right-sided aorta has not been described before. We report a case of a primary tracheal squamous carcinoma in a patient with a four-branched right-sided aortic arch. The patient underwent a tracheal resection approached by a left thoracotomy. The surgical exposure was excellent once the ligamentum arteriosum had been divided. All the aortic arch branches and the phrenic, vagus and recurrent laryngeal nerves were identified and preserved.
