Primary complete repair of partial double aortic arch and Kommerell diverticulum.

Abstract

Tracheal and esophageal stenosis caused by double aortic arch and Kommerell diverticulum is a rare but important pathologic entity in adult patients. Clinical symptoms are caused by esophageal or tracheal stenosis, or both. The present article describes a surgical method of complete repair with division of the rudimentary left arch, resection of the diverticulum, and transposition of the left subclavian artery. This method was transferred from pediatric patients and led to excellent clinical results in 2 consecutive adult patients compared with the previous technique with division of the left arch alone.
