Objective: The objective of this study was to assess early and midterm results after endovascular aortic arch repair using a double inner branch stent graft (DIBSG) in patients with aortic arch aneurysm or dissection unfit for open surgery. Methods: Between 2012 and 2018, there were 24 patients with aortic arch disease who were treated with a single model of a DIBSG (Terumo Aortic, Glasgow, United Kingdom) in nine Italian cardiovascular centers. We investigated technical success, mortality, occurrence of major complications, and need for reintervention in a multicenter, nonrandomized, retrospective fashion. Results: The in-hospital mortality rate was 16.7%. Cerebrovascular events occurred in 25% of patients and major strokes in 12.5%. Two patients experienced a retrograde dissection (8.3%), whereas none reported any type I or type III endoleak. During a mean follow-up of 18 months (range, 1-60 months), one patient died of a nonaortic cause and one reported a nonarch-related major stroke. No late secondary intervention was needed during the follow-up. Excluding from the analysis the first six patients treated until 2014 as part of the learning curve, in-hospital mortality, major stroke, and retrograde dissection rates were 11.1%, 11.1%, and 5.6%, respectively. Conclusions: Endovascular aortic arch repair using this model of DIBSG is feasible, and results are acceptable for a new technique in a high-risk subset of patients. Operative mortality suffers the effect of a learning curve, whereas midterm aorta-related survival is promising. Endovascular repair of aortic arch disease with a DIBSG should always be considered to give high-risk patients a chance of repair. Large-scale studies are needed to assess the long-term durability of this technique.

Abstract

Objective: The objective of this study was to assess early and midterm results after endovascular aortic arch repair using a double inner branch stent graft (DIBSG) in patients with aortic arch aneurysm or dissection unfit for open surgery. Methods: Between 2012 and 2018, there were 24 patients with aortic arch disease who were treated with a single model of a DIBSG (Terumo Aortic, Glasgow, United Kingdom) in nine Italian cardiovascular centers. We investigated technical success, mortality, occurrence of major complications, and need for reintervention in a multicenter, nonrandomized, retrospective fashion. Results: The in-hospital mortality rate was 16.7%. Cerebrovascular events occurred in 25% of patients and major strokes in 12.5%. Two patients experienced a retrograde dissection (8.3%), whereas none reported any type I or type III endoleak. During a mean follow-up of 18 months (range, 1-60 months), one patient died of a nonaortic cause and one reported a nonarch-related major stroke. No late secondary intervention was needed during the follow-up. Excluding from the analysis the first six patients treated until 2014 as part of the learning curve, in-hospital mortality, major stroke, and retrograde dissection rates were 11.1%, 11.1%, and 5.6%, respectively. Conclusions: Endovascular aortic arch repair using this model of DIBSG is feasible, and results are acceptable for a new technique in a high-risk subset of patients. Operative mortality suffers the effect of a learning curve, whereas midterm aorta-related survival is promising. Endovascular repair of aortic arch disease with a DIBSG should always be considered to give high-risk patients a chance of repair.
