Surgical treatment for right aortic arch with Kommerell's diverticulum.

Kommerell's diverticulum causes compression of the esophagus between the aberrant origin of the left subclavian artery and ascending aorta, leading to dysphagia or dyspnea. We describe 3 cases of successful surgical treatment of right aortic arch with Kommerell's diverticulum and aberrant origin of the left subclavian artery, using a right anterolateral partial sternotomy. This allows both resection of the Kommerell's diverticulum as well as reconstruction of the aberrant origin of the left subclavian artery anatomically.
