"First in Man" Total Percutaneous Aortic Arch Repair With 3-Inner-branch Endografts: A Report of Two Cases.

Abstract

Aneurysms of the arch are a complex clinical problem and a technical challenge. Currently, over 40% of patients are considered unfit for conventional open surgery, requiring a cardiopulmonary bypass and hypothermic circulatory arrest. In experienced hands and appropriate anatomic conditions, arch-branched graft technology has shown to be a safe and effective alternative to open conventional surgery to patients that historically have had no surgical options. This report summarizes the first in man implant of a three-vessel arch branch stent graft using a total percutaneous approach without the need for exposure of the cervical arteries-a surgical step with inherent problems and risks. This approach was performed in two consecutive patients, a 66-year-old woman with a chronic post type A dissection 60 mm diameter aneurysm of the aortic arch, and a 72-year-old man with a 70 mm saccular degenerative atheromatous aortic arch aneurysm. Technical success was obtained in both cases. The patients were extubated in the operating theatre. Neither suffered any pre- or postoperative neurological deficits. Both were discharged home after remarkably uneventful hospital stays. There were no access complications. Postoperative computerized tomography scans and ultra-sound confirmed patent supra-aortic branches and completely excluded aneurysms. Our new truly minimally invasive approach demonstrates that it is possible to manage one of the most challenging treatments of aortic pathologies without any surgical incision. Further, evaluation and experience are required to confirm these promising results.
