Surgical Treatment for Kommerell's Diverticulum Associated with a Right-Sided Aortic Arch and an Aberrant Left Subclavian Artery: Endovascular or Hybrid.

Abstract

A right-sided aortic arch, associated with an aberrant left subclavian artery and a Kommerell’s diverticulum, is a rare congenital anomaly. Case 1: A 53-year-old man, complaining of dysphasia, underwent a two-stage hybrid operation. Total arch replacement with the reconstruction of supra-aortic vessels was performed via a median sternotomy. Thoracic endovascular aortic repair was subsequently completed with the femoral approach. Case 2: A 81-year-old man, complaining of syncope and dizziness, underwent thoracic endovascular aortic repair after endovascular aneurysm repair for a common iliac artery aneurysm. Treatment strategies for Kommerell’s diverticulum should be individually determined depending on the clinical situation and anatomical features.
