Comparison of endovascular repair with branched stent graft and open repair for aortic arch aneurysm. | LitMetric

AI Article Synopsis

  • The study compares the outcomes of two surgical methods for treating aortic arch aneurysms: traditional open repair (OPEN) and thoracic endovascular aneurysm repair with a handmade branched stent graft (bTEVAR).
  • A total of 129 patients were treated, with similar midterm mortality rates observed in both groups, but the bTEVAR group had a higher incidence of late additional procedures needed.
  • While bTEVAR showed low early mortality rates comparable to open repair, it required more follow-up interventions, suggesting a trade-off in technique choice for high-risk patients.

Article Abstract

Objectives: Although conventional open repair is our preference for patients with aortic arch aneurysms, we have often chosen thoracic endovascular aneurysm repair (TEVAR) with a handmade branched stent graft (bTEVAR) in high-risk patients. The aim of this study was to compare the midterm clinical outcomes of our bTEVAR technique to those of the open repair.

Methods: Between January 2007 and December 2014, we treated 129 patients with aortic arch aneurysm by means of either conventional open repair (OPEN, n = 61) or bTEVAR (n = 68) at our institution.

Results: The mean ages were 70.5 ± 12.7 years in the OPEN group and 72.7 ± 12.5 years in the bTEVAR group (P = 0.32). The aetiologies included true aneurysm in 101 patients (78.3%) and chronic dissection in 26 (20.1%). There were 2 (3.3%) in-hospital deaths in the OPEN group and 3 (4.4%) in the bTEVAR group. The mean follow-up duration was 3.0 ± 2.1 years (2.4 ± 1.9 years in the OPEN group and 3.6 ± 2.3 years in the bTEVAR group). There was no difference in 5-year aneurysm-related mortality between groups (10.7% in OPEN vs 12.8% in bTEVAR, P = 0.50). In terms of late additional procedures, however, none were required in the OPEN group, whereas 10 (15.4%) additional endovascular repairs and 4 (6.2%) open repairs were required in the bTEVAR group.

Conclusions: Our bTEVAR could be performed with low early mortality, and it yielded similar midterm aneurysm-related mortality to that of conventional open repair. However, these patients undergoing this technique required more late additional procedures than those undergoing conventional open repair.
