Hybrid Procedure for a Kommerell's Diverticulum in a Right-Sided Aortic Arch

Abstract

A rare case of an aneurysmal Kommerell's diverticulum in a right-sided aortic arch was successfully treated using a hybrid procedure comprising total arch replacement and percutaneous stent grafting. A 65-year-old man with dysphagia was diagnosed with an ectatic right-sided aortic arch and a saccular aneurysm of the Kommerell's diverticulum. Since its radical resection during a single surgery was unfeasible because of its complex configuration, a 2-stage procedure was adopted.
