Abstract

Objective: The therapeutic strategy for extended aortic arch aneurysms remains controversial and has changed substantially since thoracic endovascular aortic repair was introduced. We applied single-stage hybrid (s-hybrid) total arch replacement (TAR), which involved ascending aorta replacement and debranching of arch vessels, consecutively performed with thoracic endovascular aortic repair for extended arch aneurysms. The aim of this study was to investigate the short-term results of s-hybrid TAR and to clarify the benefit of this method. Methods: We reviewed the operative results of 62 patients who underwent elective s-hybrid TAR or conventional TAR (c-TAR) through the median approach from 2008 to 2017. We used the s-hybrid approach in 15 patients and the c-TAR approach in 47 patients. In both groups, axillary arterial perfusion and selective antegrade cerebral perfusion under moderate hypothermia were applied for brain protection. We compared the perioperative outcomes of the two groups. Results: We completed s-hybrid TAR in all 15 patients with extended aneurysms. The s-hybrid group required shorter times for myocardial ischemia, selective antegrade cerebral perfusion, and circulatory arrest of the lower body compared with the c-TAR group. The patients with complicated recurrent laryngeal nerve palsy and long ventilation support times were fewer in the s-hybrid group. No patient had substantial endoleaks or permanent paraplegia. The in-hospital mortality rates were 6.7% in the s-hybrid group and 0% in the c-TAR group. Conclusions: The s-hybrid TAR has the same or better perioperative outcomes compared with the c-TAR approach. For extended aneurysms, this technique could resolve the problem of respiratory failure induced by left thoracotomy and also resolve the problem of rupture during the waiting period in staged surgery.
