title: Endovascular repair of thoracic aortic aneurysm associated with right-sided aortic arch: report of two cases.
abstract: Right-sided aortic arch (RAA) is a rare congenital disorder. We describe herein two cases of thoracic aortic aneurysm with a right aortic arch and right-sided descending aorta treated with thoracic endovascular aortic repair (TEVAR). In one case, a 70-year-old man with Edwards type 1 RAA underwent TEVAR using a Relay stent-graft (Bolton Medical, Barcelona, Spain). In another case, a 72-year-old woman with Edwards type 3 RAA underwent TEVAR using a Kawasumi Najuta stent-graft (Kawasumi Laboratories, Inc., Tokyo, Japan) with the "buffalo horn chimney technique", our original method for left subclavian artery flow preservation. The postoperative courses were uneventful. Postoperative computed tomography showed complete exclusion of the aneurysm without endoleakage. Compared to conventional open surgical repair, TEVAR is challenging in patients with a RAA and right-sided descending aorta. However, our results showed that TEVAR might be feasible and a treatment option even in a patient with a RAA and right-sided descending aorta.
