Hybrid repair combined with open surgery and endografting for lesions in right aortic arch: report of three cases.

Three cases with lesions in the right aortic arch (RAA) are presented. For two patients, whose RAA contained a retroesophageal segment, the primary treatment was total arch replacement (TAR) for acute type A dissection or severe arch angulation with thoracic endovascular aneurysm repair (TEVAR) as second-stage surgery. The third patient, who had RAA with mirror image branching, underwent supra-aortic bypass followed by TEVAR. There was no operative mortality, but the condition of two patients who underwent TAR was complicated by bilateral recurrent nerve palsy, which can be critical. The combination of TEVAR and supra-aortic bypass might thus be preferable for patients with RAA.
