Frozen Elephant Trunk to Exclude the Kommerell Diverticulum Associated with Double Aortic Arch in Adult Redo Patient

Abstract

Kommerell diverticulum can be associated to several types of vascular rings, including double aortic arch. Surgical indications for vascular rings and Kommerell diverticulum include bulging symptoms onto trachea and esophagus too. Moreover, the aneurysmal enlargement over time can eventually cause acute aortic syndromes. Management of this pathology in adulthood is challenging and many techniques have been proposed, notably hybrid solutions. Herein, we report the case of a patient, who underwent redo surgery with frozen elephant trunk technique, caused by persisting symptoms after a previous operation of vascular ring interruption.
