    Abstract:
    BACKGROUND: Hybrid aortic arch repair is an invasive approach to the surgical management of distal aortic arch aneurysm. The complications associated with hybrid aortic arch repair, such as stroke and endoleaks, are not uncommon and late reintervention is frequent. We retrospectively reviewed our experience of distal aortic arch aneurysm repair using the stented elephant trunk procedure with left subclavian artery (LSCA)-left common carotid artery (LCCA) transposition in the hybrid repair era. METHODS: Between May 2009 and September 2016, 19 patients with distal aortic arch aneurysm underwent LSCA-LCCA transposition with stented elephant trunk implantation under hypothermic cardiopulmonary bypass with selective antegrade cerebral perfusion. All patients were males with a median age of 51±14 (range 20-69) years. RESULTS: There were no in-hospital deaths. Continuous renal replacement therapy was not required in patients with preoperative renal dysfunction after surgery. No neurologic deficits were observed in any patients prior to hospital discharge. One patient underwent concomitant thoracic endovascular aortic repair after this technique. One case required reoperation due to bleeding. One patient required debridement due to poor wound healing. During a mean follow-up of 33±21months, one patient died. CONCLUSIONS: Satisfactory results were obtained in suitable patients undergoing surgery for distal aortic arch aneurysm using LSCA-LCCA transposition with stented elephant trunk implantation in the hybrid repair era. The straightforward nature of the surgical approach, with avoidance of the complications related to hybrid aortic arch repair and reduction of late re-intervention favours this technique for treating distal aortic arch aneurysm.
