Two Cases of Thoracic Aortic Aneurysm with Right Aortic Arch: Comparison of Two Operative Strategies for Hybrid Thoracic Endovascular Repair

抄録

Hybrid TEVAR was performed in 2 patients with right aortic arch accompanied by Kommerell’s diverticulum and aortic aneurysm. In patient 1, total debranch + TEVAR was performed with 1-stage median sternotomy. In patient 2, total arch replacement and insertion of a peripheral elephant trunk were performed first, followed by TEVAR. No endoleaks or aortic events were observed in either case during the observation period, and both patients had good postoperative clinical courses. We report our experience with two such cases that were treated with two different methods of hybrid TEVAR, and discuss the merits and demerits of each treatment method.
