Simplified total arch reconstruction with a stented graft for extended aortic arch dilation

Abstract

Background: Reconstruction of the aortic arch and its three supra-aortic vessels remains a great surgical challenge with postoperative complications. We present a simplified total arch reconstruction with a modified stent graft (s-TAR) and compared its operative outcomes with conventional total arch replacement (c-TAR).Methods: This retrospective analysis of prospectively collected data from all consecutive patients who had ascending aortic aneurysm with extended aortic arch dilation and underwent simultaneous ascending aorta replacement and aortic arch reconstruction with the s-TAR or c-TAR between 2018 and 2021. The indication for intervention was maximum diameter of ascending aorta >55 mm and aortic arch in zone II >35 mm.Results: A total of 84 patients were analyzed: 43 in the s-TAR group and 41 in the c-TAR group. No inter-group differences were found for sex, age, comorbidities, or EuroSCORE II results. All patients were successfully treated with s-TAR or c-TAR, and none died intraoperatively. Cardiopulmonary bypass, selective cerebral perfusion, and lower-body circulatory arrest time were significantly shorter in the s-TAR group, which also had a lower incidence of prolonged ventilation and transient neurologic dysfunction. No patient in either group experienced permanent neurologic dysfunction. The incidence of recurrent laryngeal nerve injury and paraplegia was markedly increased in the c-TAR group; however, no such events were observed in the s-TAR group. Both perioperative blood loss and the incidence of reoperation for bleeding were significantly lower in the s-TAR group. The in-hospital mortality rate was 0% in the s-TAR group and 4.9% in the c-TAR group. The s-TAR group had significantly shorter ICU stay and lower total hospitalization costs. Conclusions:The s-TAR technique is a safe and effective alternative for total arch reconstruction with shorter operation time, lower rate of postoperative complications and lower total hospitalization costs compared with c-TAR.

A new minimal invasive technique with in-situ stent-graft fenestration for type A aortic dissection

“…However, the mainstream surgical approach for the three supra-aortic branches is hindered by complicated procedures, high time consumption, and significant surgical trauma [ 13 ]. Previously, our team introduced a simplified total arch reconstruction method for extended aortic arch dilation, which yielded satisfactory operative results [ 14 ]. To simplify the procedure and reduce the risk of serious complications associated with TAAD, we designed an innovative in-situ stent-graft fenestration (ISSF) technique for minimally invasive aortic arch reconstruction.…”

The evolution of open total arch replacement: a case of different strokes for different folks

“…Zheng et al recently reported on a simplified approach to open total arch replacement (s-TAR) using a physician-modified stent graft ( 1 ). In the s-TAR procedure, the authors replace the ascending aorta with a Dacron graft, and then perform antegrade deployment of a stent graft under circulatory arrest with antegrade selective cerebral protection.…”
